GORE® GR Gaskets

Exceptionally resistant to creep, cold flow and aggressive media, this 100 % ePTFE gasket sheet reliably seals steel piping and equipment.

Unmatched in sealing reliability, this unique product is ideal for sealing steel pipe and equipment flanges across a range of aggressive fluids. Gain the benefits of PTFE gasketing without the problems of creep and cold flow – along with a level of high-temperature and blowout resistance that is superior to any other PTFE sheet gasket. Highly conformable, it compresses into an extremely tough gasket that seals tight, even on irregular flanges.

SPECIFICATIONS

Material	100% expanded PTFE (polytetrafluoroethylene), with multidirectional strength
Chemical Resistance	Chemical resistance to all media pH 0-14, except molten alkali metals and elemental fluorine.
Operating Range	The maximum applicable pressure and temperature depend mainly on the equipment and installation. Typical use: -60 °C to 230 °C (-76 °F to 445 °F); industrial full vacuum⁽¹⁾ to 40 bar (580 psi) Maximum use: -269 °C to 315 °C (-452 °F to 600 °F); full vacuum to 210 bar (3000 psi) For applications outside the typical use range, Gore recommends an application specific engineering design calculation and extra care during installation. Also, consider retorquing after a thermal cycle when the equipment has returned to an ambient temperature condition. Please contact Gore if further guidance is required.
Shelf Life	Expanded PTFE is not subject to aging and can be stored indefinitely.
