- F.A.Q: PTFE Seals
- PTFE seals are assembled, made-to-order radial shaft seals based on PTFE (polytetrafluroethylene or Teflon. Teflon is a registered trademark of E.I. DuPont).

- 6. How are they installed? - Top
- PTFE lip seals do not have the elastic properties that rubber lip seals possess; therefore, installation
and handling are crucial elements in their successful operation and function. Shaft keyways and
splines, as well as drill holes, ports, and shaft steps (sharp-edges), have the potential to tear PTFE lip seals. If the hardware permits, these obstructions can be covered and accounted for by using thin walled, nylon installation tools. Installation is more difficult when the shaft is being installed from the oil side of the seal. In any case, when the shaft is being installed in this manner an installation cone or bullet is recommended.
