??Rubber seals due to its low manufacturing cost and easy to use, and therefore is widely used in all kinds of dynamic and static seal.

??Standard; Most of the countries to develop series product standards for rubber seals,

??Which American standard (AS 568),

??The Japanese standard (JIS B 2401),

??3601/1 international standard (ISO) is more general.

??Rubber seal sealing mechanism: rubber seal is a kind of automatic two-way sealing element. When installation, the radial and axial precompression and the initial seal ability of the rubber seal. It increases with the increase of system pressure.

??Work performance parameters: static sealing dynamic sealing pressure without retaining ring, up to 20 mpa; Have a collar, up to 40 mpa; When using a special ring, up to 200 mpa. Without retaining ring, up to 5 mpa; Have a retaining ring, high pressure. Biggest reciprocating movement speed can reach 0.5 m/s, maximum rotational speed can reach 2.0 m/s. Temperature: general occasions - 30 °C ~ + 110 °C; Special rubber: 60 °C ~ + 250 °C; Rotating occasions: - 30 °C ~ + 80°C
