O rings are generally divided into two main group. Static seals in which there is little or no relative motion between the mating surfaces and dynamic seals which function between surfaces with definite relative motion such as the seal on the piston of hydraulic cylinder. Also used in vacuum sealing
O rings are manufactured as per AS 568, BS, R, ISO 3601, GR, SW, JAP std. – G, P, S, V series with tolerances as per DIN 3771/1, ISO 3601/1, NFT-47- 501 G , IS 9975
