O-RING SEALS IN THE DESIGN OF HYDRAULIC MECHANISMS

N O-ring seal is a synthetic-rubber torus fitting in a groove in the piston surface and sealing against the cylinder wall of an hydraulic mechanism.

O-ring seals have been found to be effective, dependable, and economical for both static and moving seal applications. If molded of super synthetic rubbers, they may be successfully used with fluid pressures up to 3000 psi.
