SEAL by KSD


Seal Materials (We Use)


  1. BUNA-N (NBR, Acrylnitrile butadiene india rubber)
    The material is for general use. It is widely used in air, water, oil (w/o additives). The service temperature range is from -10℃ ∼ +90℃.
  2. FKM (VITON, Fluoride india rubber)
    It is used in hydrocarbon liquids such as gasoline, solvents, etc. Please confirm the availability before the usage. The service temperature range is from - 20℃ ∼ +180℃ (The steam is not recommended.)
  3. EPDM (Ethylane propylene india rubber)
    It is used in hot water and low pressure steam. The service temperature range is from - 20℃ ∼ +130℃.
  4. H-NBR ( Hydrogenated nitrile rubber )
    The material is widely used in R-134a and also used in high temperature applications. The service temperature range is from - 20 ℃ ∼ +150℃.
  5. PTFE (TEFLON, Polytetrafluoroethene)
    The chemical resistance is excellent and is stable in low and high temperatures. The material is not flexible, therefore it is hard to make seal. The material is used in steam and corrosive media. The service temperature range is from -20 ℃ ∼ +200℃.
We provide the technique problem consulting and offer special designs for special purposes in different environment conditions.
