RubberFab PTFE Enveloppe Tri-Clamp Pakking

Has the same chemical resistance as PTFE, beter resistance to temperature fluctations.
WNL

PTFE Enveloppe gaskets have the same chemical resistance as normal PTFE gaskets.  Envelope gaskets are sanitary clamp gaskets with a PTFE outer shell, and your choice of EPDM or FKM inserts

They have almost no extractables, low absorption and excellent resistance to process liquids. They can be used for longer periods in both water and continuous steam. The torque for tightening is lower than for the normal PTFE gaskets and leakage is less likely.
