Compared With The Alternatives

FKM O-ringsFKM handles most industrial chemistry at far lower cost; FFKM is for media and temperatures that go beyond FKM's range.
FFKM sealsThe same material in a different form. O-rings fit standard circular grooves; moulded seal profiles are used where the equipment needs a specific shape.

Use Guide

  • Reserve FFKM for the seals whose failure is genuinely expensive
  • Provide the full chemical list including cleaning and purge media
  • Give both normal and peak temperatures
  • Record the compound grade so repeat orders match

Questions

Questions Buyers Ask About This Product

What makes FFKM different from other elastomers?

Its resistance to a vast range of aggressive chemicals, solvents and corrosive agents, combined with the ability to keep sealing at extreme temperatures.

Which applications use FFKM O-rings?

Aerospace, biotechnology, automotive fuel systems and high temperature engine components, petrochemical work and semiconductor manufacturing.

Are custom sizes available?

Yes, alongside standard sizes. Send the groove dimensions and operating conditions.

Is FFKM suitable for purity critical processes?

Yes, it is used in biotechnology to ensure purity and prevent contamination in processes.

How do I decide between FKM and FFKM?

By the chemistry, the temperature and what a failure costs. If FKM's range covers the application, it is the more economical choice.
