Various applications of O-rings

The o-ring is suitable for being installed on various mechanical equipment, under the specified temperature, pressure, and in different liquid and gas media, it plays a sealing role in static or moving state. Various types of Seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. . Silicone Rubber O-Ring Silicone O-ring has excellent heat resistance, low temperature elasticity and particularly excellent resistance to oxidation and ozone. Good electrical insulation properties (volume resistance greater than 1016 ohm.cm, breakdown voltage above 30kv/mm), corona resistance and arc resistance. The sealing ring manufacturers add conductive carbon black, nickel powder, aluminum powder, and silver powder O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion seals, it is limited to low-speed rotary seals. The O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role.
