O-rings FEP

FEP O-rings for DIN 11864 couplings and other components
W0B

O-rings FEP

These O-rings consist of a seamless and uniform FEP jacket which completely encloses a core material of FKM (viton) or Silicone. The combination of these components creates an O-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments.

features

  • DN10 to DN100 sizes always in stock for the FEP-FKM combination
  • High Chemical Resistance
  • Economical and effective replacement for Kalrez (FFKM)
  • Non Stick Surface: provides easy cleanup of viscous materials
  • Low Coefficient of Friction, self lubricating surface
  • Sterilizable with SIP and autoclavable
  • Low Compression Set:  these o-rings consist of either a solid silicone or Viton core encapsulated in FEP resin (with .010 to .045 wall depending cross section) which meets or exceeds requirements of L-P389A and ASTM-D-2166
