Chesterton 7K Rod and Piston Seal

The Chesterton 7K Rod and Piston Seal is a single-acting piston cup with a positive flared lip design to optimize dynamic sealing forces. Reduced frictional force and low heat generation result in low wear, which prolongs seal and cylinder service life and reliability. The seal is responsive to low-pressure fluctuations, thus optimizing the sealing effect in most operating conditions. The rugged construction is the ideal replacement to upgrade from traditional rubber-based seals for use in light- to medium-duty
hydraulic or pneumatic applications. High performance thermoset polyurethane materials provide superior wear resistance
and excellent memory retaining lip flare.
