GORE-TEX GR®

Sheet Gasketing

Key Features• Chemically inert• Soft & conformable• Dimensionally stable• High tensile strength• Resistant to creep & cold flow

Key Benefits• Seals irregular flanges• Retains stress; minimum retorque• Sealing reliability

Ideal For Practically AllGasketing ApplicationsGORE–TEX GR® sheet gasketing ismade from 100% expanded PTFE.Because it is dimensionally stable, yetconformable, it is ideal for real–worldflange conditions.

GORE–TEX GR® sheet gasketing hasthe benefits of conventional PTFEsheet with significantly less creep andcold flow that is commonly associatedwith that material. It conforms to roughsealing surfaces, yet compresses intoan extremely tough gasket that makesa tight, long lasting seal.

GORE–TEX GR® Style R sheetgasketing is a more rigid version, witha six–fold increase in bend resistance.This makes gasket positioning easier inlarge flanged openings or wheregaskets must be positioned inhard–to–reach places.

The Most Dependable Joint SealantGORE-TEX® joint sealant, the originalform-in-place gasketing, is engineeredfor the reliable sealing of large, complexor damaged flanges. Made from 100%expanded PTFE, this gasketing material,when compressed, forms a thin yetstrong, durable gasket that is highlyresistant to creep and cold flow. Theseal remains tight and rarely needsretorquing. And, installation is easy —just peel off the adhesive backing,apply to surface, and overlap the ends.

GORE-TEX® joint sealant minimizesthe potential for leaks, process disrup-tion, and lost production. It reducesmaintenance time, safety risks, andthe possibility of catastrophic failure.It is the most reliable means of opti-mizing long-term system performance.

From the inventors of expandedPTFE, GORE-TEX® joint sealant isbacked by thirty years of industrysuccess, ongoing improvements, andtechnical support.

Low Stress to SealSince GORE-TEX® joint sealant has a very low stress-to-sealrequirement, it makes an effective gasket on more delicateassemblies such as plastic, FRP or graphite. And, GORE-TEX®

joint sealant requires less stress to seal on rough flangesurfaces.

Tight SealSoft and conformable, GORE-TEX® joint sealant forms a thin,wide seal when compressed in the flange. The conform-ability of the material allows the gasket to easily fill in allthe areas of micro-deviation across the flange surface, foran incredibly tight seal.

Installation is simpleCompletely clean the sealing surfaces to remove any dirt,corrosion, oil, or leftover gasket material. Cut one end ofthe gasketing using the skiving technique shown in FigureA. Remove the adhesive backing and position the tape atthe center of the effective sealing width, placing the skivejust inside a bolt hole. Fit the gasket tape around the entireflange circumference. Lay the tape across the skive, com-pleting with a second cut as shown in Figure B, allowing 1"of overlap. Horizontally cut off the excess, leaving a totalthickness of approximately 120% of the original. At least 3progressive torque sequences in a star or 180º methodshould be used. Lastly, perform a circular torque check toensure a tight, long-lasting seal.

Installation Guidelines- Tape Width = Approx. 75% of effective sealing surface.

- Thickness = 1/8" for most flanges (up to 0.040” flangedeviation). 1/16" for equipment with tight tolerances. Forgreater flange deviation, please contact Gore for a recom-mendation.

Easy to Install and RemoveMaintenance time is kept to a minimum during bothinstallation and replacement. The self-adhesive backingmakes GORE-TEX® gasket tape quick and easy to apply,even on irregular surfaces and those that are slightly oily orwet. To make a gasket, simply remove the backing, apply toflange, cut to length and cross over the ends — there’s neverany wasteful scrap. For full-face gasketing, the bolt holes canbe punched out after application with a hole punch or anysharp object. When it’s time to remove, it usually peelscleanly off the flange with no scraping required.

Outstanding VersatilityGORE-TEX® gasket tape is effective at temperatures rangingfrom -450°F to +600°F and is compatible with all chemicalsin the 0-14 pH range (except for elemental fluorine andmolten alkali metals). Its high tensile strength allows it towithstand internal pressures up to 3,000 psig (1,800,000 P xT factor). The material is non-contaminating and non-aging.It is perfectly suited for cryogenic applications and isFDA/USDA accepted for use in the food and pharmaceuticalindustries.

The lower bolt loads needed to seal with the GORETM UniversalPipe Gasket will support standardization of non-metallic gasketmaterials in steel, FRP, and glass-lined steel flanges.

Blowout SafetyThe GORETM Universal Pipe Gasket (Style 800) delivers improved creep relaxation and higher tensile strength, whichmakes the gaskets more resistant to blowout. In Hot Blowouttesting (HOBT), when compared to a leading filled PTFEmaterial, the GORETM Universal Pipe Gasket showed superiorresults. Tested in accordance with HOBT1 and HOBT2procedures, blowout of the filled PTFE material occured whenthe internal pressure reached 1900 psi at 450°F. Style 800 didnot experience blowout at 450°F and 2900 psi during the tests;thus the temperature was increased with pressure maintaineduntil blowout did occur at 682°F. The significantly higherblowout resistance of the Style 800 gasket is a result of theimproved tensile and mechanical properties achieved with thenew technology.
