HERCULES PSM-DPAC PISTON SEAL

    PSM-DPAC Piston Seal

    This style of seal provides effective static and dynamic sealing while the groove on the sealing surface acts as a lubrication reservoir to reduce friction. Grooves on both sides prevent blow by during sudden pressure changes and a premium NBR square energizer prevents twisting. This product is molded from premium urethane which provides excellent extrusion and wear resistance.
