PTFE (Teflon) is chemically inert to almost everything, with a huge temperature range and a naturally low-friction, non-stick surface. It is the go-to for the most corrosive chemical service and for food and pharmaceutical equipment. We laser-cut custom PTFE gaskets to your exact dimensions with no minimum order and ship within 24 hours.

- Acid and solvent process piping
- Semiconductor and lab equipment
- Non-stick and low-friction sealing surfaces
- Cryogenic and high-purity systems
When to Choose PTFE
Choose PTFE for the most aggressive chemicals or for food and pharmaceutical service where nothing may leach or react. It is not elastomeric and can cold-flow under constant load, so for flexible or vibration sealing choose an elastomer such as Viton or EPDM.
PTFE Gasket FAQs
What is PTFE (Teflon) gasket material?
PTFE is a rigid fluoropolymer that is chemically inert to nearly every substance, non-stick, and stable across an extremely wide temperature range — ideal for corrosive and high-purity service.
Is PTFE food-safe?
Yes — FDA-compliant PTFE grades are available for food, dairy, and pharmaceutical equipment because the material does not leach or react.
What is the downside of PTFE gaskets?
PTFE can cold-flow (creep) under sustained bolt load and is not elastic. For flexible or vibration-damping seals, choose an elastomer such as Viton or EPDM.
