Product Description:
The AN6226-22 U-Cup is a precision-molded hydraulic seal made from 70 durometer Nitrile, specifically designed to meet the demands of pneumatic and low-pressure hydraulic applications. Engineered to conform with the Army-Navy AN6226 specification, this U-Cup provides excellent sealing performance in dynamic applications by increasing sealing force as internal pressure rises. With a profile that minimizes friction and maintains fluid retention under pressure, it’s ideal for cylinders, actuators, and a wide range of fluid power systems operating up to 500 PSI.
