O-ring specification design determines the use of the product
O-type sealing ring is suitable for installation on various mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, in the static or moving state of the 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 all kinds of instruments and meters, a large number of various types of sealing components. Silicone O-ring Silicone O-ring has excellent heat resistance, low temperature elasticity and particularly excellent oxidation and ozone resistance, with high permeability and selectivity for gas transmission. Good electrical insulation performance (volume resistance greater than 1016 eur.cm, breakdown voltage above 30kv/mm), corona resistance and arc resistance. However, the O-type sealing ring with conductive carbon black, nickel powder, aluminum powder and silver powder is mainly used for static sealing and reciprocating sealing. When used for rotary operating seals, only low speed rotary sealing devices. The O-ring is generally installed in the groove of the outer circle or the inner circle with a rectangular cross section.
