PTFE & PCTFE Seals and Components for Chemical Processing
Few materials survive concentrated acids, solvents and reactive gases. PTFE resists almost every industrial chemical, which is why it lines valves and pumps across the process industry.
Centroid supplies PTFE and filled PTFE gaskets, seals and valve seats, PTFE-metal bonded seats and bearings, and PCTFE components for low-permeability, high-purity systems.
We machine parts to drawing, and help choose between virgin, filled and PCTFE grades based on media, pressure and temperature.
What Chemical Processing buyers need
- Resistance to acids, alkalis, solvents and oxidisers
- Low permeability for high-purity and hazardous media
- Creep resistance for bolted gaskets and valve seats
- Wide service temperature range
- Non-contaminating materials for high-purity lines
Standards commonly specified
- FDA 21 CFR 177.1550
- ASTM D4894
- ASTM D1430
Compliance varies by product and compound. Ask us for the certificates and test reports for your part.

Frequently asked questions
Which chemicals can PTFE handle?
PTFE resists nearly all industrial chemicals, including strong acids, alkalis and solvents. Exceptions include molten alkali metals and some fluorinating agents.
How do I reduce cold flow in PTFE gaskets?
Filled PTFE grades or PCTFE reduce creep and cold flow under bolt load. We can recommend a grade for your flange and media.
Do you supply PTFE valve seats?
Yes. We machine PTFE and PCTFE valve seats and PTFE-metal bonded seats to your dimensions.
Need a custom part for chemical processing?
Send a drawing or sample and our engineers will recommend a compound and quote.
