GORE™ GR Sheet Gasketing

Gasket Tape

Gain the benefits of PTFE gasketing without the problems of creep and cold flow. Unmatched in sealing reliability, GORE™ GR Sheet Gasketing provides high temperature and blowout resistant sealing that's superior to any other PTFE sheet gasket.


This sheet gasketing is made from 100% expanded PTFE. Because it is dimensionally stable, yet conformable, it is ideal for real world flange conditions. It conforms to rough surfaces, yet compresses into a very tough gasket that makes a tight, long lasting seal.

GORE™ GR Sheet Gasketing is ideal for sealing steel flanges for many aggressive chemicals.


Key Features

  • Increased resistance to creep and cold flow
