O-ring is a kind of rubber sealing ring with a round section, because its cross-section is O-type, it is called O-type rubber sealing ring, also known as O-ring.
O-ring scope of application
O-ring is suitable for installation on a variety of mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, in the state of rest or motion to seal. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various types of instrumentation, a large number of various types of sealing components are used. O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion seals, it is limited to low-speed rotary seals. O-type sealing rings are generally installed in grooves with rectangular sections on the outer or inner circles to seal the role. O-rings still play a good sealing and shock absorption role in oil, acid and alkali, wear, chemical attack and other environments. Therefore, the O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.
