GORE® GR Sheet Gasketing

Get the benefits of using PTFE Gasketing without having to worry about creep or cold flow. The GORE GR Sheet gasketing is unmatched in sealing reliability and provides a superior level of high temperature and blow-out resistance.

Since it is constructed of 100% proprietary expanded PTFE and has multi-directional strength, the GORE GR Sheet gasketing is excellent for real-world flange conditions. It is dimensionally stable, yet conformable which makes it a dependable sealing solution.

GORE GR Sheet Gasketing prior to installation.

Although it offers the standard benefits that are expected from conventional PTFE Sheet gasketing, the GORE GR Sheet gasketing eliminates cold flow and creep relaxation, which is commonly associated with that type of material. It can compress into an extremely tough and durable gasket that makes a long-lasting and tight seal that conforms to rough sealing surfaces. This makes it the ideal application for sealing equipment flanges and steel pipes that transport aggressive chemicals.
