Envelope Gasket

PTFE Envelope Gasket
Tri Clamp Envelope Gaskets are specialty tri-clamp seals featuring a PTFE (Teflon®) outer envelope over an EPDM or Viton core insert —providing exceptional chemical resistance and sealing flexibility.

Designed for demanding sanitary applications such as brewery racking arms, these envelope gaskets offer the chemical inertness of PTFE combined with the memory and resilience of elastomeric materials.
