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



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


    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

    Hollow Silicone Rubber:  75-80A

    Water absorption: <0.01 


    1.Excellent chemical resistance, is suitable for almost all chemical medium (strong oxidation, reducing solvent);

    2.Good corrosion resistance ( Strong acid and alkali solvent );

    3.Wide temperature range -200°C~260°C; 

    4.Good compression resistance ≥30%;

    5.Low Coefficient of Friction (only 0.1 ~ 0.2);

    6.Good resistance to dissolve (≤0.1%) ;

    7.High pressure resistantance(up to 60Mpa );

    8.Excellent sealing persistence , increase 500% life time.
