HERCULES DRTU ROD U-SEAL

    DRTU Rod U-seal

    These seals are specifically designed with a second lip on their inside diameter and engineered to attain maximum
    life and reliability in dynamic rod sealing. This feature results in reduced leakage, less friction, increased stability, and
    prevents air and contaminants from entering the cylinder.
