Question 1

Can PTFE O-Rings be used in food and medical applications?

Accepted Answer

Yes! Virgin PTFE O-rings are FDA-approved and safe for food processing, pharmaceuticals, and medical equipment due to their non-toxic and non-reactive nature.

Question 2

Are PTFE O-rings suitable for dynamic sealing applications?

Accepted Answer

While PTFE has a low coefficient of friction, its lower elasticity and tendency for cold flow can limit its use in dynamic applications. Filled PTFE compounds or spring-energized PTFE seals are often preferred for more demanding dynamic sealing.

Question 3

What is the typical lifespan of a PTFE O-ring?

Accepted Answer

The lifespan depends heavily on the operating conditions (temperature, pressure, chemical exposure, compression). In static applications with benign conditions, PTFE O-rings can last for a very long time. However, in demanding environments, periodic replacement may be necessary.
