HERCULES CTC BUFFER SEAL

    CTC DYR Buffer Seal

    These lip-type buffer seals are designed for replacement in Caterpillar® cylinders. The hinged-lip design reduces friction, heat, and wear under low-pressure conditions and acts as a check valve allowing back-pressure relief. Seals for rod sizes 2-1/8″ and under do not have a back-up ring.
