FEP Encapsulated O-Rings

FEP Encapsulated O-Rings Description:

FEP Encapsulated O-rings | Ever wanted to make Viton or silicone more chemical resistant? When you order PTFE encapsulated materials you can have the best of both worlds. PTFE Encapsulated materials are ideal for when you need the versatility of Viton® but need it to be chemically inert, or if you need the high temperature properties of silicone but also need it to be more wear resistant.
By combining the energizing properties of Silicone or Viton® with the chemical resistance of FEP / PFA Teflon® flouropolymers, you get an o-ring capable of handling extreme applications without the extreme price of Kalrez®.

Properties:

Excellent heat resistance with continuous service temperature capability of 446°F, chemical resistance including resistance to strong acids and bases, high electrical resistivity, excellent oil resistance.

Temperature Range:

-20E F to +400EF+

Uses:

Inorganic acids, alkalis, high temperature steam, polar solvents, organic bases, hydrocarbon oils, amines and amine corrosion inhibitor systems, and hydrogen sulfide bearing fluids Viton® is a registered trademark of DuPont Performance Elastomers. All rights reserved.
