PARKER PP PNEUMATIC SEAL

    Pneumatic Seal PP

    The profile PP pneumatic cushioning seal is specially designed for cushioning pistons in pneumatic cylinders.

    • No mechanical check valves required since their function is performed by the cushioning rings.
    • High cushioning consistency due to automatic centering, even in the case of misalignment of the cushioning spear and the cylinder head.
    • Optimum use of design-related cushion travel.
    • Robust seal profile for harshest operating conditions.
    • Immediate response to reversed direction thanks to incorporated venting channels.
    • Extreme wear resistance.
    • Easier installation.
    • Excellent media resistance in case of suitable compound selection.
    • Installation in closed housings.

    Range of application
    For pneumatic cylinders with end-position cushioning.
