Product Description

  O ring is a common seal in our daily life. O Ring has excellent pressure resistance, wear resistance, and has a
strong applicability to temperature and environment, so it is widely used, especially in industrial equipment and
daily appliances. For example, it is used for sealing diesel locomotives, automobiles, tractors, engineering machinery,
machine tools and various hydraulic and pneumatic components, and can bear fixed, reciprocating and rotary motion.
It has good sealing performance and is not easy to deform.

--Nitrile rubber (NBR)
  This kind of rubber NBR is mainly used to make oil resistant rubber products with excellent oil resistance and wear
resistance. It can be used in air at 120 ºC or oil at 150 ºC for a long time.

--Ethylene propylene diene monomer (EPDM)
  EPDM is widely used in housing construction, wire and cable, automobile industry and other fields. It has excellent
oxidation resistance, ozone resistance, corrosion resistance and excellent aging resistance.

--Silicone rubber (SIR)
  Silicone rubber is not only resistant to cold and heat, but also resistant to ozone and atmospheric aging. However,
its tensile strength is poor, and it does not have oil resistance. Therefore, silicone rubber seal ring is mostly used in
household appliances, such as microwave oven, water heater, electric iron, etc., and also can be used in articles
indirectly in contact with human body, such as drinking machine, kettle, etc.

--Fluororubber (FKM)
  Fluorine rubber has good ozone resistance, chemical resistance and weather resistance, and its high temperature
resistance is better than silicone rubber, but its disadvantage is poor cold resistance. It is generally used in the sealing
of fuel system and chemical plant. It is essential in aviation, aerospace, automobile, petroleum, petrochemical and
industrial pollution control.
