Pure PTFE (Polytetrafluoroethylene) from Carlock Sealing is the gold standard for sealing in extreme chemical and thermal environments. Our Virgin PTFE seals offer near-universal chemical resistance and the lowest coefficient of friction of any solid material. Precision-machined by Carlock Sealing, these seals are ideal for high-purity applications where contamination-free performance is critical.
- Universal Chemical Resistance: Immune to almost all known chemicals, solvents, and corrosive media.
- Extreme Temperature Stability: Maintains sealing integrity from -200°C (-328°F) up to +260°C (+500°F).
- Ultra-Low Friction: Self-lubricating surface prevents "stick-slip" and reduces energy loss in dynamic systems.
- High Purity: Non-toxic and FDA-compliant material, ideal for food, pharmaceutical, and semiconductor use.

While PTFE is universally resistant, it is not suitable for molten alkali metals or high-temperature fluorine gas. Performance data is provided for technical guidance only.
FAQ:
Q: Is Carlock Sealing’s PTFE FDA compliant?
A: Yes, our Virgin PTFE is naturally inert and meets FDA requirements for food contact and pharmaceutical applications.
Q: How does Pure PTFE handle pressure?
A: While Pure PTFE has excellent chemical properties, it can "cold flow" under high pressure. For high-pressure applications, Carlock Sealing recommends PEEK back-up rings or filled PTFE grades.
Q: Why choose machined PTFE from Carlock Sealing over molded seals?
A: Our CNC machining ensures a superior surface finish and tighter tolerances, which are essential for the perfect sealing of volatile fluids.
