FAQ

01.When should I choose a PTFE seal over a rubber seal?

Choose PTFE seals when:

Temperature is very high or very low

Chemicals are aggressive

High speed or dry running is involved

02.Can PTFE seals run without lubrication?

Yes, PTFE has self-lubricating properties, making it suitable for dry running applications.

03.Are PTFE seals suitable for high-speed applications?

Yes, PTFE seals perform exceptionally well at high speeds due to their low friction coefficient.

04.What shaft surface is recommended?

A hardened and polished shaft surface (≥ 55 HRC) is recommended to ensure optimal sealing performance and lifespan.

05.Can PTFE seals be customized?

Absolutely. PTFE seals can be customized in terms of size, material filling, and lip design to meet specific application needs.
