    My customer, the biggest valve company general manager, said this ring made very beautifully.


    Encapsulation:

    FEP

    The most versatile when considering overall corrosion resistance, sealing capability and temperature.Temperature range -450 to + 400 degrees F. (-267 to 205 degrees C)

    PFA

    A fluorocarbon copolymer similar to FEP but it also offers greatly improved mechanical and creep properties at elevated operating temperatures. Temperature range -450 to +500 degrees F. (-267 to +260 degrees C).

    Physical Properties of Encapsulated O-rings:

    Core material:    

    Silicon rubber: 85-90A

    Viton elastomers: 90-95A
