Envelope Seal Type III PTFE Gasket With Fillers

The PTFE Envelope Type III Tri-Clamp Gaskets offer two different inserts for your applications

A PTFE envelope gasket has the chemical resistance of PTFE and the elastomeric characteristics of EPDM or FKM Fluoroelastomer. The PTFE envelope gasket meets FDA and USP Class VI standards.

We suggest using the temperature range of the insert which would be
EPDM: -30ºF to 300ºF (-34ºC to 149ºC)
FKM: -30ºF to 400ºF (-34ºC to 204ºC)
