ESP International is your source for a wide range of Parker piston seals to meet the broad demands of the fluid power industry. Parker’s piston seal profiles are available for both uni-directional and bi-directional applications. When combined with wear rings, Parker piston seals have proven to provide long life and leak free performance.
Piston profiles are fluid seals specifically designed to function in pneumatic and hydraulic cylinder applications. The outside diameter lip is designed to seal against the cylinder bore while the inside diameter lip is designed to seal the gland. For most non-symmetrical piston profiles, the size of the seal is slightly smaller in diameter than the gland diameter. When installed, the seal stretches into the gland to ensure a tight seal with the gland and improved stability in application.
