Gore GR Sheet Gasketing is designed to outperform both conventional (filled and skived) PTFE and other ePTFE gasketing in steel piping and equipment. It has the chemical resistance of conventional PTFE sheet gasketing without the creek and cold flow commonly associated with that material. Gore GR Sheet Gasketing is stronger and has more dimensional stability than other ePTFE gaskets. It is highly conformable to rough or irregular sealing surfaces and compresses into an extremely tough gasket that creates a tight, long-lasting seal.
