The O-ring is the most widely used seal in the industry. It is easy to install, may be used as a double-acting seal and can seal pressures of up to 800 PSI. With pressures over 800 to 2,000 PSI, backup rings should be considered for higher pressures. The o-ring is typically used as a reciprocating seal, not for rotating shaft applications (Lip seals should be used for rotating shafts). READ MORE
