Rubber Fab PTFE Envelope Tri-Clamp Gaskets

Same resistances as PTFE, beter resistance against temperature differences

PTFE Envelope gaskets has the same resistance to chemicals as solid PTFE.

It has almost no extractables, has a low absorption rate and excellent resistance to process fluids. It can remain in service for longer periods of time in both water and steam for continuous use. The fastening torque is less than with PTFE and leakage will not occur very fast.
