What is the scope of application of rubber O-ring?

Rubber O-rings are suitable for mounting on various types of machinery and equipment, in the specified temperature, pressure, as well as different liquid and gas media, sealing effect at rest or movement.


In the sanitary ware, ships, automobiles, hardware, electronics, toys, appliances, aerospace equipment, machinery, and various types of instruments and meters, a large number of various types of sealing elements are applied. Rubber O-rings are mainly used for static sealing and reciprocating sealing. For rotary motion seals, it is limited to low-speed rotary seals.


Rubber O-rings are generally installed in grooves with a rectangular cross-section on the outer or inner circle to function as a seal. Rubber O-rings still play a good role in sealing, shock absorption in environments such as oil, acid and alkali, abrasion and chemical attack. Therefore, rubber O-rings are the most widely used seals in hydraulic and pneumatic transmission systems.
