Parkrimp crimpers and 71 Series fittingsParker’s 721TC hose is compatible with our one-piece 71 Series Monoblok™fittings. Manufactured from a single piece of steel, 71 Series fittings eliminate potential leak paths.

Parker 721TC and 71 Series fittings can be crimped with several of Parker’sParkrimp crimpers. So leak-free assemblies are just 1-2-3 easy steps away.

71 Series fittings feature a corrosion-resistant zinc dichromate coating and areavailable in the end connections you need,including SAE code 62 flange and Seal-Lok®.

Parker 721TC Extreme hose pushes the envelope in high-pressure applications where space is tight.Critical high-pressure applications in limited spaces call for extreme measures. That’s the time to measure off a few lengths of Parker’s new 721TC Extreme hose. With its one-half SAE 100R12 minimum bend radius and abrasion-resistant Tough Cover, 721TC Extreme hose allows you to use less hose while it guards against hose-to-hose and hose-to-object abrasion. No matter how demanding the environment – construction, forestry, agriculture, mining, you name it – 721TC Extreme hose is the one that keeps your equipment working hard.

Features• One-half SAE 100R12 minimum bend

radius means you use less hose

• Specially engineered Tough Cover compound resists abrasion in aggressive environments

• Up to 4000 psi working pressure

• No-Skive design eliminates the need to remove the cover before crimping

• Unique three-color layline makes hose easy to identify

ConstructionOil-resistant synthetic rubber inner tube;four spirals of high-tensile steel wire

reinforcement; oil-, weather-, and abrasion-resistant black synthetic MSHA-accepted rubber cover.

Application and temperature range• Petroleum-base hydraulic fluids and

lubricating oils within a temperature range of -40°F to +257°F (-40°C to +125°C)

• Water, water/oil emulsion andwater/glycol hydraulic fluids up to +185°F (+85°C)

• Air up to +158°F (+70°C); for air above 250 psi (1,7 MPa), the cover should be pin pricked
