FluidCompatibility

Fluid compatibility

This chart indicates the suit-ability of various elastomersand metals for use with flu-ids to be conveyed. It isintended as a guide onlyand is not a guarantee.Final selection of the properhose style, seal, or materialof metal components is fur-ther dependent on manyfactors including pressure,fluid and ambient tempera-ture, concentration, dura-tion of exposure, etc.

How to use the chart

1. The chart has separatesections for rating elas-tomers for use as hoseinner tubes and as seals.Ratings for a given elas-tomer may not always bethe same in both sections.

2. Both the elastomer andthe metal must be consid-ered when determiningsuitability of a combinationfor a hose assembly,adapter with o-ring, swiveljoint or coupling.

3. Locate the fluid to beconveyed and determinethe suitability of the elas-tomeric and metal compo-nents according to theresistance ratings shownfor each.

4. Specific hose part num-bers can be found underthe inner tube materialgroupings in the Hose TubeIdentification Chart below.

5. Dimensional and operat-ing specifications for eachhose can be found on thecatalog pages shown witheach hose part number.

6. Information on o-ringsand seal options for swiveljoints and couplings, andhow to specify them, areshown in the respectivesections of this catalog.

7. For further details on theproducts shown in this cat-alog, and their applications,contact:

Resistance key rating

E = Excellent – Fluid haslittle or no effect.

G = Good – Fluid hasminor to moderateeffect.

C = Conditional – Serviceconditions should bedescribed to EatonAeroquip for determi-nation of suitability forapplication.

U = UNSATISFACTORY

The differences betweenratings “E” and “G” are rel-ative. Both indicate satisfac-tory service. Where there isa choice, the materials rated“E” may be expected togive better or longer servicethan those rated “G”.

NOTE: Special precautionsare necessary in gaseousapplications due to thepotential volume ofgaseous fluid in the sys-tem. Unless the cover isperforated, hose styleswith rubber or thermoplas-tic covers are not suitablefor gases above 250 psi.Hose styles with perforatedcovers are so noted in theirconstruction descriptions.

WARNINGCompatibility of hose

fittings with conveyed fluid isan essential factor in avoidingchemical reactions that mayresult in release of fluids orfailure of the connection withthe potential of causingsevere personal injury orproperty damage.

Hydraulic fluids & lubricating oils

The following is a represen-tative list of fluids and man-ufacturers. The fluids aregrouped under generic“family” heads andarranged alphabetically. Foreach generic “family” listingwe have included maximumfluid temperature recom-mendations for the fourhose classifications on page400 (1 through 4). Two maxi-mum fluid temperature rat-ings are listed under desig-nations of “H” and “LP”.

The “H” designation is forhydraulic service up to themaximum rated operatingpressure of any particularhose in the classification.The “LP” designation is forlow-pressure service suchas lubricating oil systems orlow-pressure hydraulicreturn lines.

The letter “U” in the boxindicates unsatisfactoryresistance to the fluid type.

Fluid temperature ratingsare predicated on maximumallowable ambient tempera-tures as follows:

Classifications 1 and 3(Synthetic Rubber andThermoplastic Elastomer)

“H” fluid temp. ratings:+140°F ambient

“LP” fluid temp. ratings:+180°F ambient

Classification 2 (PTFE)


“LP” fluid temp ratings:+400°F ambient

Classification 4 (AQP)


“LP” fluid temp. ratings:+250°F ambient

(If “H” fluid temperature is+225°F or less, allowableambient temperature maybe increased to +200°F)

Ambient temperatures inexcess of those recom-mended, in conjunctionwith maximum fluid tem-peratures, can materiallyshorten the service life ofthe hose.

CAUTION: The fluid manu-facturer’s recommendedmaximum operating tem-perature for any specificnamebrand fluid should bescrupulously observed bythe user. These recom-mended temperatures canvary widely between namebrands of different fluidcompositions, even thoughthey fall into the samegeneric “family” of fluids.

Exceeding the manufactur-er’s recommended maxi-mum temperature canresult in fluid breakdown,producing by-products thatare harmful to elastomericproducts, as well as othermaterials in the system. If amanufacturer's recommend-ed maximum temperaturefor his specific fluid is lowerthan that for the hose rat-ing, it should take prece-dence over the hose ratingfor service usage.

SAE Recomended PracticesSelection, installation and maintenance of hose andassemblies — SAE J1273 October 1996The following recommendationson selection, installation andmaintenance of hose assemblieswas established by the S.A.E. in1991. Please read these generalinstructions carefully. Moredetailed information on many ofthese subjects is covered in thiscatalog.

1. Scope—Hose (also includes hoseassemblies) has a finite life and thereare a number of factors which willreduce its life.

This recommended practice isintended as a guide to assist systemdesigners and/or users in the selec-tion, installation, and maintenance ofhose. The designers and users mustmake a systematic review of eachapplication and then select, install,and maintain the hose to fulfill therequirements of the application. Thefollowing are general guidelines andare not necessarily a complete list.

WARNING: IMPROPER SELECTION,INSTALLATION, OR MAINTENANCEMAY RESULT IN PREMATURE FAIL-URES, BODILY INJURY, OR PROP-ERTY DAMAGE.

2. References

2.1 Applicable Documents—The fol-lowing publications form a part ofthis specification to the extent speci-fied herein. The latest issue of SAEpublications shall apply.

2.1.1 SAE PUBLICATIONS—Availablefrom SAE, 400 CommonwealthDrive, Warrendale, PA 15096-0001.

J516—Hydraulic Hose Fittings

J517—Hydraulic Hose

3. Selection—The following is a listof factors which must be consideredbefore final hose selection can bemade.

3.1 Pressure—After determining thesystem pressure, hose selectionmust be made so that the recom-mended maximum operating pres-sure is equal to or greater than thesystem pressure. Surge pressureshigher than the maximum operatingpressure will shorten hose life andmust be taken into account by thehydraulic designer.

3.2 Suction—Hoses used for suctionapplications must be selected toinsure the hose will withstand thenegative pressure of the system.

3.3 Temperature—Care must betaken to insure that fluid and ambienttemperatures, both static and tran-sient, do not exceed the limitations ofthe hose. Special care must be takenwhen routing near hot manifolds.

3.4 Fluid Compatibility—Hoseselection must assure compatibilityof the hose tube, cover and fittingswith the fluid used. Additional cautionmust be observed in hose selectionfor gaseous applications.

3.5 Size—Transmission of power bymeans of pressurized fluid varieswith pressure and rate of flow. Thesize of the components must be ade-quate to keep pressure losses to a

minimum and avoid damage to thehose due to heat generation orexcessive turbulence.

3.6 Routing—Attention must begiven to optimum routing to minimizeinherent problems.

3.7 Environment—Care must betaken to insure that the hose and fit-tings are either compatible with orprotected from the environment towhich they are exposed.Environmental conditions such asultraviolet light, ozone, salt water,chemicals, and air pollutants cancause degradation and premature fail-ure and, therefore, must be considered.

3.8 Mechanical Loads—Externalforces can significantly reduce hoselife. Mechanical loads which must beconsidered include excessive flexing,twist, kinking, tensile or side loads,bend radius, and vibration. Use ofswivel-type fittings or adapters maybe required to insure no twist is putinto the hose. Unusual applicationsmay require special testing prior tohose selection.

3.9 Abrasion—While hose isdesigned with a reasonable level ofabrasion resistance, care must betaken to protect the hose fromexcessive abrasion which can resultin erosion, snagging and cutting ofthe hose cover. Exposure of the rein-forcement will significantly acceleratehose failure.

3.10 Proper End Fitting—Care mustbe taken to insure proper compatibili-ty exists between the hose and cou-pling selected based on the manufac-turer’s recommendations substantiat-ed by testing to industry standardssuch as SAE J517. End fitting compo-nents from one manufacturer areusually not compatible with end fit-ting components supplied by anothermanufacturer (i.e., using a hose fit-ting nipple from one manufacturerwith a hose socket from anothermanufacturer). It is the responsibilityof the fabricator to consult the manu-facturer’s written instructions or themanufacturer directly for proper endfitting componentry.

3.11 Length—When establishingproper hose length, motion absorp-tion, hose length changes due to pres-sure, as well as hose and machine tol-erances must be considered.

3.12 Specifications andStandards—When selecting hose,government, industry and manufac-turers’ specifications and recommen-dations must be reviewed as applicable.

3.13 Hose Cleanliness—Hose com-ponents vary in cleanliness levels.Care must be taken to insure that theassemblies selected have an adequatelevel of cleanliness for the application.

3.14 Electrical Conductivity—Certainapplications require that hose be non-conductive to prevent electrical cur-rent flow. Other applications requirethe hose to be sufficiently conductiveto drain off static electricity. Hoseand fittings must be chosen with these needs in mind.

4. Installation—After selection ofproper hose, the following factorsmust be considered by the installer.

4.1 Pre-Installation Inspection—Prior to installation, a careful exami-nation of the hose must be per-formed. All components must bechecked for correct style, size andlength. In addition, the hose must beexamined for cleanliness, I.D.obstructions, blisters, loose cover, orany other visible defects.

4.2 Follow Manufacturers’Assembly Instructions—Hoseassemblies may be fabricated by themanufacturer, an agent for or cus-tomer of the manufacturer, or by theuser. Fabrication of permanentlyattached fittings to hydraulic hoserequires specialized assembly equip-ment. Field-attachable fittings (screwstyle and segment clamp style) canusually be assembled without spe-cialized equipment although manymanufacturers provide equipment toassist in the operation.

SAE J517 hose from one manufactur-er is usually not compatible with SAEJ516 fittings supplied by anothermanufacturer. It is the responsibilityof the fabricator to consult the manu-facturer’s written assembly instruc-tions or the manufacturers directlybefore intermixing hose and fittingsfrom two manufacturers. Similarly,assembly equipment from one man-ufacturer is usually not interchange-able with that of another manufactur-er. It is the responsibility of the fabri-cator to consult the manufacturer’swritten instructions or the manufac-turer directly for proper assemblyequipment. Always follow the manu-facturer’s instructions for properpreparation and fabrication of hoseassemblies.

4.3 Minimum Bend Radius—Installation at less than minimumbend radius may significantly reducehose life. Particular attention must begiven to preclude sharp bending atthe hose/fitting juncture.

4.4 Twist Angle and Orientation—Hose installations must be such thatrelative motion of machine compo-nents produces bending of the hoserather than twisting.

4.5 Securement—In many applica-tions, it may be necessary torestrain, protect, or guide the hose toprotect it from damage by unneces-sary flexing, pressure surges, andcontact with other

mechanical components. Care mustbe taken to insure such restraints donot introduce additional stress orwear points.

4.6 Proper Connection of Ports—Proper physical installation of thehose requires a correctly installedport connection while insuring thatno twist or torque is put into the hose.

4.7 Avoid External Damage—Properinstallation is not complete withoutinsuring that tensile loads, side loads,kinking, flattening, potential abrasion,thread damage, or damage to sealingsurfaces are corrected or eliminated.

4.8 System Check Out—After com-pleting the installation, all air entrap-ment must be eliminated and the sys-tem pressurized to the maximum sys-tem pressure and checked for properfunction and freedom from leaks.

NOTE: Avoid potential hazardousareas while testing.

5. Maintenance—Even with properselection and installation, hose lifemay be significantly reduced withouta continuing maintenance program.Frequency should be determined bythe severity of the application andrisk potential. A maintenance pro-gram should include the following asa minimum.

5.1 Hose Storage—Hose products instorage can be affected adversely bytemperature, humidity, ozone, sunlight,oils, solvents, corrosive liquids andfumes, insects, rodents and radioac-tive materials. Storage areas should berelatively cool and dark and free ofdust, dirt, dampness and mildew.

5.2 Visual Inspection—Any of thefollowing conditions requires replace-ment of the hose:

(a) Leaks at fitting or in hose (leakingfluid is a fire hazard)

(b) Damaged, cut, or abraded cover(any reinforcement exposed)

(c) Kinked, crushed, flattened, ortwisted hose

(d) Hard, stiff, heat cracked orcharred hose

(e) Blistered, soft, degraded, or loosecover

(f) Cracked, damaged, or badly cor-roded fittings

(g) Fitting slippage on hose

5.3 Visual Inspection—The followingitems must be tightened, repaired, orreplaced as required:

(a) Leaking port conditions

(b) Clamps, guards, shields

(c) Remove excessive dirt buildup

(d) System fluid level, fluid type, andany air entrapment

5.4 Functional Test—Operate thesystem at maximum operating pres-sure and check for possible malfunc-tions and freedom from leaks.

NOTE: Avoid potential hazardousareas while testing.

5.5 Replacement Intervals—Specificreplacement intervals must be con-sidered based on previous servicelife, government or industry recom-mendations, or when failures couldresult in unacceptable down time,damage, or injury risk.

Flow Capacities

For suction hose, follow the same procedure except usesuggested velocity range for pump inlet lines in the righthand column.

Based on Formula

G.P.M. x 0.3208AREA (SQ. IN.) =

VELOCITY (FT./SEC.)

*Suggestions are for oils having a maximum viscosity of315 S.S.U. at +100°F (+38°C) and operating at tempera-tures between +65°F and +155°F (+54°C to +69°C).Under certain conditions, velocities in pressure lines canbe increased up to 25 feet per second. Contact Aeroquipwith specific information on your application.

To convert U.S. gallons into Imperial gallons multiply U.S.gallons by 0.83267. Imperial gallons into U.S. gallons multi-ply Imperial gallons by 1.20095. U.S. gallons to litres multi-ply by 3.785. Litres to U.S. gallons, multiply by 0.2642.

Flow capacities of hose assemblies at suggested flow velocities

The chart below is designed and provided as an aid in thedetermination of the correct hose size.

Example: At 13 U.S. gallons per minute, what is proper hosesize within the suggested velocity range for pressure lines?

Solution: Locate 13 U.S. gallons per minute in the left handcolumn and 10 feet per second in the right hand column(the center of the suggested velocity range for pressurelines). Lay a straightedge across the two points. The insidediameter is shown in the center column nearest thestraight edge.

Hose Routingand Installation

Under pressure, a hosemay change in length.Always provide some slackin the hose to allow for thisshortening or elongation.

(However, excessive slackin hose lines may causepoor appearance.)

When 90° adapters wereused, this assembly becameneater-looking and easier to

inspect and maintain. It usesless hose, too!

At bends, provide sufficienthose so that it does nothave a bend radius less thanits recommended minimumbend radius. Too tight a bendmay kink the hose and

restrict or stop the fluidflow. In many cases theproper use of adapters andhose fittings can eliminatetight bends or kinks.

In applications where thereis considerable vibration orflexing, allow additional hoselength. The metal hose fit-tings, of course, are not flex-

ible, and proper installationprotects metal parts fromundue stress, and avoidskinks in the hose.

If a hose is installed with atwist in it, operating pres-sures tend to force itstraight. This can loosen the

fitting nut. Twisting cancause reinforcement sepa-ration and the hose couldburst at the point of strain.

When hose lines pass nearan exhaust manifold orother heat source, theyshould be insulated by aheat resistant boot,firesleeve or a metal baffle.In any application, bracketsand clamps keep hoses inplace and reduce abrasion.

For installations whereabrasion to hose cover can-not be prevented with theuse of clamps or brackets,a steel protective coil orabrasion resistant sleeveshould be placed over thehose.

Analyzing Failures

Everyone in maintenanceencounters hose failures.Normally, there is no prob-lem. The hose is replacedand the equipment goesback in operation.Occasionally the failurescome too frequently – thesame equipment with thesame problems keep pop-ping up. At this point thetask is to determine andcorrect the cause of theserepeated failures.

Improper application

Beginning with the mostobvious, the most commoncause of hose failures –Improper Application –compare the hose specifi-cations with the require-ments of the application.

Pay particular attention tothe following areas:

1. The maximum operatingpressure of the hose.

2. The recommended tem-perature range of thehose.

3. Whether the hose israted for vacuum service.

4. The fluid compatibility ofthe hose.

Check all of these areasagainst the requirements ofthe application. If they don’tmatch up, you need toselect another hose. It’s agood idea at this point tocall on your local hose dis-tributor for assistance inselecting the proper hose.Eaton’s distributors, forexample, are well equippedto perform this service foryou. Distributor personnelattend special trainingcourses in hydraulics andhose application conductedby the company. Or, if yourproblem is particularly diffi-cult, the distributor can callon the services of Eaton’s

Field Engineering Staff. Thecompany will send in ahose and hydraulic special-ist to study the problemand come up with a solution.

Improper assembly andinstallation

The second major cause ofpremature hose failure isimproper assembly andinstallation procedures. Thiscan involve anything fromusing the wrong fitting on ahose, to poor routing of the hose.

Eaton provides excellenttraining material that youcan use to combat thisproblem. A little time spentin training your mainte-nance people could pay big dividends in reduceddowntime.

You can make use of thematerial available fromEaton to improve your hoseassembly and installationtechniques.

This material is availablefree from Eaton Corporation14615 Lone Oak Road,Eden Prairie, MN 55344USA, 952/937-9800.

External damage

External damage can rangefrom abrasion and corro-sion, to hose that iscrushed by a lift truck.These are problems thatcan normally be solved sim-ply once the cause is identi-fied. The hose can be re-routed or clamped, or a firesleeve or abrasion guardcan be used.

In the case of corrosion,the answer may be as sim-ple as changing to a hosewith a more corrosionresistant cover or re-routingthe hose to avoid the corro-sive element.

Faulty equipment

Too frequent or prematurehose failure can be thesymptom of a malfunctionin your equipment. This is afactor that should be con-sidered since prompt cor-rective action can some-times avoid serious andcostly equipment break-down. Reprints of an articleon “TroubleshootingHydraulic Systems,” whichtells you how to spot prob-lems in a hydraulic systemare available from Eaton.

Faulty hose

Occasionally a failure prob-lem will lie in the hoseitself. The most likely causeof a faulty rubber hose isold age. Check the lay lineon the hose to determinethe date of manufacture.(2Q99 means second quar-ter 1999.) The hose mayhave exceeded its recom-mended shelf life. If yoususpect that the problemlies in the manufacture ofthe hose (and don’t jump tothis conclusion until youhave exhausted the otherpossibilities) contact yourdistributor. Given effectivequality control methods,the odds of a faulty batchof hose being released forsale are extremely small.So make sure that youhaven’t overlooked someother problem area.

Analyzing failures

A physical examination ofthe failed hose can oftenoffer a clue to the cause ofthe failure. Following are 22symptoms to look for alongwith the conditions thatcould cause them:

1. Symptom: The hosetube is very hard and hascracked.

Cause: Heat has a tenden-cy to leach the plasticizersout of the tube. This is amaterial that gives the hoseits flexibility or plasticity.

Aerated oil causes oxida-tion to occur in the tube.This reaction of oxygen ona rubber product will causeit to harden. Any combina-tion of oxygen and heat willgreatly accelerate the hard-ening of the hose tube.Cavitation occurring insidethe tube would have thesame effect.

2. Symptom: The hose iscracked both externally andinternally but the elas-tomeric materials are softand flexible at room tem-perature.

Cause: The probable rea-son is intense cold ambientconditions while the hosewas flexed. Most standardhoses are rated to –40°F(–40°C). Some AQP hosesare rated at –55°F (–49°C).Military specified hoses aregenerally rated to –65°F(–54°C). PTFE hose is ratedto –100°F (–73°C). SomeEverflex Polyon thermoplas-tic hoses are rated at –65°F(–54°C).

3. Symptom: The hosehas burst and examinationof the wire reinforcementafter stripping back thecover reveals random bro-ken wires the entire lengthof the hose.

Cause: This would indicatea high frequency pressureimpulse condition. SAE impulse test requirementsfor a double wire braid rein-forcement are 200,000cycles at 133% of recom-mended working pressure.The SAE impulse testrequirements for a four spi-ral wrapped reinforcement(100R12) are 500,000cycles at 133% maximumoperating and at +250°F(121°C). If the extrapolatedimpulses in a systemamount to over a million ina relatively short time a spi-ral reinforced hose wouldbe the better choice.

4. Symptom: The hosehas burst, but there is noindication of multiple bro-ken wires the entire lengthof the hose. The hose may

have burst in more thanone place.

Cause: This would indicatethat the pressure hasexceeded the minimumburst strength of the hose.Either a stronger hose isneeded or the hydraulic cir-cuit has a malfunctionwhich is causing unusuallyhigh pressure conditions.

5. Symptom: Hose hasburst. An exam-ination indi-cates the the wire braid isrusted and the cover hasbeen cut, abraded or deteri-orated badly.

Cause: The primary func-tion of the cover is to pro-tect the reinforcement.Elements that may destroyor remove the hose coversare:

1. Abrasion

2. Cutting

3. Battery Acid

4. Steam Cleaners

5. Chemical CleaningSolutions

6. Muriatic Acid (for cementclean-up)

7. Salt Water

8. Heat

9. Extreme Cold

Once the cover protectionis gone the wire reinforce-ment is susceptible toattack from moisture orother corrosive matter.

6. Symptom: Hose hasburst on the outside bendand appears to be ellipticalin the bent section. In thecase of a pump supply line,the pump is noisy and veryhot. The exhaust line on thepump is hard and brittle.

Cause: Violation of the min-imum bend radius is mostlikely the problem in bothcases. Check the minimumbend radius and make surethat the application is withinspecifications. In the caseof the pump supply line par-tial collapse of the hose iscausing the pump to cavi-tate creating both noise andheat. This is a most serioussituation and will result incatastrophic pump failure ifnot corrected.

7. Symptom: Hoseappears to be flattened outin one or two areas andappears to be kinked. It hasburst in this area and alsoappears to be twisted.

Cause: Torquing of ahydraulic control hose willtear loose the reinforce-ment layers and allow thehose to burst through theenlarged gaps between thebraided plaits of wirestrands. Use swivel fittingsor joints to be sure there isno twisting force on ahydraulic hose.

8. Symptom: Hose type hasbroken loose from the rein-forcement and piled up atthe end of the hose. In somecases it may protrude fromthe end of the hose fitting.

Cause: The probable causeis high vacuum or thewrong hose for vacuumservice. No vacuum is rec-ommended for double wirebraid, 4 and 6 spiral wirehose unless some sort ofinternal coil support isused. Even though a hoseis rated for vacuum service,if it is kinked, flattened outor bent too sharply thistype of failure may occur.

9. Symptom: Hose hasburst about six to eight inch-es away from the end fit-ting. The wire braid is rust-ed. There are no cuts orabrasions of the outer cover.

Cause: Improper assemblyof the hose end fittingallowing moisture to enteraround the edge of the fit-ting socket. The moisturewill wick through the rein-forcement. The heat gener-ated by the system willdrive it out around the fit-ting area but six to eightinches away it will beentrapped between theinner line and outer covercausing corrosion of thewire reinforcement.

10. Symptom:There are blis-ters in the cover of the hose.If one pricks the blisters, oilwill be found in them.

Cause: A minute pin hole inthe hose tube is allowing thehigh pressure oil to seep be-tween it and the cover.Eventually it will form a blis-ter wherever the cover adhe-sion is weakest. In the caseof a screw together reusablefitting insufficient lubricationof the hose and fitting cancause this condition becausethe dry tube will adhere tothe rotating nipple and tearenough to allow seepage.Faulty hose can also causethis condition.11.Symptom: Blistering ofthe hose cover where agaseous fluid is being used.

Cause:The high pressuregas is effusing through thehose tube, gathering underthe cover and eventuallyforming a blister whereverthe adhesion is weakest.Specially constructed hosesare available for high pres-sure gaseous applications.Your supplier can adviseyou on the proper hose touse in these cases.12. Symptom: Fitting blewoff of the end of the hose.

Cause: It may be that thewrong fitting has been puton the hose. Recheck man-ufacturer’s specificationsand part numbers.In the case of a crimped fit-ting the wrong machinesetting may have beenused resulting in over orundercrimping. The socketof a screw together fittingfor multiple wire braidedhose may be worn beyondits tolerance. The swagingdies in a swaged hoseassembly may be wornbeyond the manufacturer’stolerances.The fitting may have beenapplied improperly to thehose. Check manufacturer’sinstructions. The hose mayhave been installed withoutleaving enough slack tocompensate for the possi-ble 4% shortening thatmay occur when the hoseis pressurized. This willimpose a great force on thefitting. The hose itself maybe out of tolerance.

13. Symptom: The tube ofthe hose is badly deteriorat-ed with evidences of ex-treme swelling. In somecases the hose tube maybe partially “washed out.”

Cause: Indications are thatthe hose tube is not com-patible with the agent beingcarried. Even though theagent is normally compati-ble, the addition of heat canbe the catalyst that cancause inner liner deteriora-tion. Consult your hosesupplier for a compatibilitylist or present him with asample of the fluid beingconducted by the hose foranalysis. Make sure thatthe operating temperaturesboth internal and externaldo not exceedrecommendations.

14. Symptom: Hose hasburst. The hose cover isbadly deteriorated and thesurface of the rubber iscrazed.

Cause: This could be simplyold age. The crazed appear-ance is the effect of weather-ing and ozone over a periodof time. Try to determine theage of the hose. Some man-ufacturers print or embossthe cure date on the outsideof the hose. As an example,Aeroquip hose would show“4Q01” which would meanthat the hose was manufac-tured during the fourth quar-ter (October, November orDecember) of 2001.

15. Symptom: Hose isleaking at the fittingbecause of a crack in themetal tube adjacent to thebraze on a split flange head.

Cause: Because the crackis adjacent to the braze andnot in the braze this is astress failure brought on bya hose that is trying toshorten under pressure andhas insufficient slack in it todo so.

We have cured dozens ofthese problems by lengthen-ing the hose assembly orchanging the routing to relievethe forces on the fitting.

16. Symptom: A spiral rein-forced hose has burst andliterally split open with thewire exploded out and badlyentangled.

Cause: The hose is tooshort to accommodate thechange in length occurringwhile it is pressured.

17.Symptom: Hose is badlyflattened out in the burstarea. The tube is very harddown stream of the burstbut appears normal upstream of the burst.

Cause: The hose has beenkinked either by bending ittoo sharply or by squashingit in some way so that amajor restriction was creat-ed. As the velocity of thefluid increases through therestriction the pressuredecreases to the vaporiza-tion point of the fluid beingconveyed. This is commonlycalled cavitation, and caus-es heat and rapid oxidationto take place which hardensthe tube of the hose downstream of the restriction.

18.Symptom: Hose has notburst but it is leaking pro-fusely. A bisection of thehose reveals that the tubehas been gouged throughto the wire braid for a dis-tance of approximately twoinches.

Cause: This failure wouldindicate that erosion of thehose tube has taken place. Ahigh velocity needle like fluidstream being emitted froman orifice and impinging at asingle point on the hose tubewill hydraulically remove asection of it. Be sure that thehose is not bent close to aport that is orificed.

In some cases where highvelocities are encounteredparticles in the fluid cancause considerable erosionin bent sections of the hoseassembly.

19. Symptom: The hose fit-ting has been pulled out ofthe hose. The hose has beenconsiderably stretched out inlength. This may not be ahigh pressure application.

Cause: Insufficient supportof the hose. It is very neces-sary to support very longlengths of hose, especially ifthey are vertical. The weightof the hose along with theweight of the fluid inside thehose in these cases is beingimposed on the hose fitting.This force can be transmittedto a wire rope or chain byclamping the hose to it muchlike the utilities support bun-dles of wire from pole topole. Be sure to leave suffi-cient slack in the hosebetween clamps to make upfor the possible 4% shorten-ing that could take placewhen the hose is pressur-ized.

20. Symptom: The hose hasnot burst but it is leaking pro-fusely. An examination of thebisected hose reveals thatthe tube has burst inwardly.

Cause: This type of failure iscommonly referred to ashose tube blow down. It isusually associated with verylow viscosity fluids such asair, nitrogen, freon and othergases. What happens is thatunder high pressure condi-tions the gases will effuseinto the pores of the hosetube charging them up likeminiature accumulators. Ifthe pressure is very sudden-ly reduced to zero theentrapped gases literallyexplode out of the tube oftentearing holes in it. In somehose constructions a second

hose tube made from aplastic such as nylon, isinserted into the hose.A small leak will allow thegaseous fluid to seepbetween the two inner lin-ers and when the pressureis reduced to zero the inner-most liner will collapsebecause of the entrappedpressure around its outerdiameter.21. Symptom: PTFE hoseassembly has collapsed inter-nally in one or more places.

Cause: One of the mostcommon causes for this isimproper handling of thePTFE assembly. PTFE is athermoplastic material whichis not rubber-like. When bentsharply it simply collapses.This type of collapse is local-ized in one area and is radial.When the PTFE tube is fold-ed longitudinally in one ormore places this could bethe result of heat (which soft-ens the hose tube) alongwith vacuum conditionsinside of it. Because of theadditional tension of the wirebraid reinforcement inherentwith this type of hose, thereis always a radial tension onthe tube trying to push it in.Rapid cycling from a very hotagent in the hose to a verycold agent in the hose canproduce the same type offailure. Eaton offers an inter-nal support coil that will elim-inate this problem. 22. Symptom: A PTFE hoseassembly has developed apin hole leak or several pinhole leaks.

Cause:This situation occurswhen a petroleum base fluid,with a low viscosity, is flow-ing at a high velocity. Thiscondition can generate highvoltage due to static electric-ity. The high voltage is seek-ing a ground connection andthe only ground connectionavailable is the braided stain-less steel reinforcement. Thiscauses an electric arc, whichpenetrates through the PTFEtube as it travels to the rein-forcement. Specially con-structed PTFE tubes areavailable that have enoughcarbon black in them so as tobe conductive. They will“drain off” the static electrici-ty and preclude this problem.

This connection is commonlyused in refrigeration, automotiveand truck piping systems. Theconnector is frequently made ofbrass. Both the male and femaleconnectors have 45° seats. Theseal takes place between themale flare the female cone seat.

The threads hold the connectionmechanically. CAUTION: In the–02, –03, –04, –05, –08 and –10sizes, the threads of the SAE45° flare and the SAE 37° flareare the same. However, thesealing surface angles are notthe same.

This is a radial O-Ring sealconnection developed inGermany and commonlyused for hydraulic applicationin underground mines. Themale contains an exterior O-Ring and backup ring, plus agroove to accept the “sta-ple”. The female has asmooth bore with two holes

for the stable. A “U” shapedretaining clip or staple isinserted through the twoholes, passing through thegroove in the male to lockthe connection together. Theseal takes place by contactbetween the O-Ring in themale and the smooth bore ofthe female.

†Measure to the closest 1/64-inch.

SAE J518 4-Bolt Flange*

This connection is commonlyused in fluid power systems.There are two pressure rat-ings. Code 61 is referred to asthe “standard” series andCode 62 is the “6000 psi”series. The design concept forboth series is the same, butthe bolt hole spacing andflanged head diameters arelarger for the higher pressure,Code 62 connection.The female (port) is anunthreaded hole with four boltholes in a rectangular patternaround the port. The male con-

sists of a flanged head,grooved for an O-Ring, andeither a captive flange or splitflange halves with bolt holes tomatch the port. The seal takesplace on the O-Ring, which iscompressed between theflanged head and the flat sur-face surrounding the port. Thethreaded bolts hold the con-nection together.

*SAE J518, JIS B 8363,ISO/DIS 6162 and DIN 20066are interchangeable, exceptfor bolt sizes.

How to Measure

Four Bolt Flange—Firstmeasure the port hole diam-eter using the caliper. Next,measure the longest bolthole spacing from center-to-center (Dimension “A”) ormeasure the flanged headdiameter.

This BSPT (tapered) connec-tion is similar to the NPT,except that the thread pitchesare different in most sizes, andthe thread form and O.D.s are

close but not the same.Sealing is accomplished bythread distortion. A threadsealant is recommended.

*Frequently, the thread size is expressed as a fractional dimension preceded by the letter“G” or the letter “R”. The “G” represents a parallel thread and the “R” indicates a taperedthread. For example, BSPP 3/8–19 may be expressed as G 3/8, and BSPT 3/8–19 may beexpressed as R3/8.

The BSP (parallel) male is similar to the NPSM maleexcept the thread pitches aredifferent in most sizes.

The female swivel BSPP has atapered nose/Globeseal flare-less swivel which seals on thecone seat of the male.

This connection consists of acommon male and two differ-ent females. The MillimetriqueSeries is used with whole

number metric O.D. tubingand the GAZ Series is usedwith fractional number metricO.D. pipe size tubing.

JIS B 8363 4-BoltFlange*

This connection is commonlyused in fluid power systems.There are two pressure rat-ings. Type I (Code 61) isreferred to as the “standard”series and Type II (Code 62) isthe “6000 psi” series. Thedesign concept for both seriesis the same, but the bolt holespacing and flanged headdiameters are larger for thehigher pressure, Type II con-nection. Both metric and inchbolts are used.

The female (port) is anunthreaded hole with four boltholes in a rectangular patternaround the port. The male con-sists of a flanged head,grooved for an O-Ring, andeither a captive flange or splitflange halves with bolt holesto match the port. The sealtakes place on the O-Ring,which is compressed betweenthe flanged head and the flatsurface surrounding the port.The threaded bolts hold theconnection together.*JIS B 8363, ISO/DIS 6162, DIN 20066,and SAE J518 are interchangeable, exceptfor bolt sizes.

How to Identify O-Ring Pilot Thread Sizes

This connection is common toair conditioning systems, bothin vehicle and commercialapplications. Both the male andfemale halves of the connec-tions have a pilot, either long orshort. The seal takes place bycompressing an O-ring adjacentto the bead of the tube. Thethreads hold the connectiontogether mechanically.

When compared to rigidpipe, hydraulic tubing offersthe following advantages:

1. Size for size, tubing islighter in weight, easierto handle and can bebent more easily thaniron pipe.

2 Bent tubing reduces pres-sure drop and turbulencein the system because iteliminates sudden changein the direction of thefluid flow.

3.Hydraulic tubing reducesthe number of connec-tions required, thus reducing material andlabor costs.

4.Fewer joints means lowercosts and fewer points ofpotential leakage.

5.The use of tube fittingsmakes every joint a unionwhich permits easier,faster maintenance andrepair work.

6.The ORS-TF Tube Fittingeliminates the need forthreading, brazing orwelding.

Tube bending

To reduce the number offittings in a tube assembly,bend the tubing wheneverpossible.

Steel tubing can be bent inmany sizes by using a handbender designed for steeltubing. For production quan-tities, or for larger sizes, apower bending tool is gen-erally used. Contact Eatonfor additional tube bendinginformation.

Tube routing and installation

Tubing manufacturers willadvise the correct radii forvarious types and wallthicknesses of tubing.Kinks, flattened bends,wrinkles and tube breakagecan be avoided by the useof proper tube bendingequipment.

Avoid straight line connec-tions whenever possible,especially in short runs.

Fluid conveying systems(see figures 2, 3 and 4)should be designed to fol-low the contour of theequipment. They are easierto install and present aneater appearance. Longruns should be supported bybrackets or clamps. Allheavy systems componentsshould be bolted or clampedto eliminate tubing fatigue.

Inspect the tubing to seethat it conforms to therequired specificationsbefore installation.

Tubes should align with thecenter line of the fittings,without distortion or ten-sion. Tubing should not besprung into position (seefigure 1) to be assembledto the fitting. If this occursthe tubing has not beenproperly fabricated, andwhen installed and con-nected, places the tubingunder stress.

A new method for calculat-ing the equivalent metricconversion to Mpa from psiwas utilized. This methodprovides an extremely easyand consistent method ofconversion to arrive at arounded metric units using

7 Mpa for each 1000 psi.The resulting Mpa pressurein never more than 1.7%higher that the mathemati-cally correct Mpa unit whenthe pressure in higher than250 psi. All operating pres-sures of SAE J517 hoses

are above 250 psi exceptfor most of 100R4 and the76mm (-48) and larger sizesof 100R5. Therefore allfiles of previous test resultsshould not be compro-mised.
