Rubber O-ring is a device used for piston sealing in reciprocating hydraulic cylinder, which is made of polyurethane TPU, CPU and rubber. Excellent sealing performance and high working life. The working life of dynamic pressure seal is 5-10 times higher than that of conventional rubber seal products, up to tens of times. Under some conditions, it can have the same life as the sealing matrix.
It is mainly used in the occasions requiring sealing. Classification of rubber O-rings
It mainly includes uhso ring, uhpo ring, uno ring, DHO ring, piston rod O ring, high temperature resistant O ring, high pressure resistant O ring, corrosion resistant O ring and wear-resistant O ring. The rubber O-ring still plays a good role in sealing and damping in the environment of oil resistance, acid and alkali resistance, abrasion resistance, chemical erosion, etc. Rubber O-ring is one of the most widely used seals in hydraulic and pneumatic transmission systems.
