Teflon™ (PTFE) Envelope Gasket

Type III PTFE Envelope gaskets are a good option when your process demands TeflonTM but you have temperature cycling that can cause cold flow, creep and leaking with traditional solid TeflonTM Tri-Clamp gaskets.

Teflon & PTFE Envelope Gaskets are made from a genuine TeflonTM outer shell with a choice of EPDM or Viton filler.  They are available in designs to fit Standard, Schedule 5, and ISO ferrules and come with FDA, 3A and USP Class VI certifications. Contact us to learn more about our TeflonTM envelope gaskets and other sanitary gaskets today!
