PTFE Gaskets

PTFE

One of the most chemically-resistant materials available, PTFE can fit the bill for extreme sealing with sheet gasketing, gasket tape, joint sealant, and universal gasket configurations. In addition to resisting most chemicals, the expanded PTFE gaskets are outstanding at resisting creep and cold flow. There are also gaskets created specifically for low bolt load, or for use in sealing fragile pipe flanges.

Sealing Devices offers a complete line of Gore PTFE gasketing materials and joint sealants.
