PTFE (polytetrafluoroethylene) Tri-Clamp Gaskets offer outstanding chemical inertness and thermal stability, making them ideal for harsh or aggressive process fluids. Because PTFE is highly non-reactive, these gaskets are often used in chemical processing, pharmaceutical, and specialty food applications. Some designs use an envelope configuration (PTFE shell over an elastomer core) to combine flexibility with chemical resistance
Key Features
- Compatible with USP Class VI / FDA sanitary standards in many variants
- Exceptional chemical resistance — inert to most acids, bases, solvents, and process media
- Wide temperature tolerance (e.g. –100 °F to +450 °F)
- Low friction, non-stick surface that minimizes residue adhesion
- Long service life under harsh conditions
- Available in full PTFE or PTFE-envelope/insert (hybrid) styles to balance sealability and performance
- Standard sizes to match tri-clamp flange OD ranges (½”, ¾”, 1″, 1½”, 2″, 2½”, 3″, 4″, 6″, 8″, 10″, 12″)
We use 24 hours’ service with carriers in most cases so that you can get your order delivered on time.
Rush orders will be delivered by our special carrier service on your own charge.

Chemically inert PTFE for aggressive process media
Meets many USP Class VI / FDA sanitary requirements
Wide temperature range: approx. –100 °F to +450 °F
Low-friction, non-stick surface minimizes residue buildup
Full PTFE or PTFE-envelope (elastomer-core) styles for sealability vs. resistance
Long service life in harsh, CIP/SIP and chemical environments
Standard tri-clamp sizes: 1/2″–12″ (matches sanitary flange ODs)
