It has a wide range of applications and different materials can be selected to meet the requirements of various media and various motion conditions.

    O-ring is a kind of squeeze type seal. The basic working principle of squeeze type seal is to rely on the elastic deformation of the seal to cause contact pressure on the sealing contact surface. If the contact pressure is greater than the internal pressure of the sealed medium, it will not occur. Leakage, otherwise, leakage occurs.

      The commonly used materials are: NBR nitrile rubber, SIL silicone, EPDM, FKM fluorine rubber, CR neoprene, HNBR hydrogenated nitrile rubber, NR natural rubber.
