  5. Piston
    The piston is of fine grained alloy iron, incorporating a combination of u-cup seals and cast iron rings, ensuring non-leak Hi-Lo pressure performance. The piston is pilot fitted and threaded to the rod.
  6. Cylinder Barrel and Seals
    The barrel is of steel tubing, honed to a fine finish to assure superior sealing, minimum friction and maximum seal life. It is step cut on the O.D. of both ends for an O-Ring and molded back-up washer. Milwaukee Cylinder’s unique non-extrusion barrel seal design provides a positive leak tight seal.

  9. Cushions
    Cushion are machined to close tolerance to provide positive, smooth deceleration at the end of stoke. on all bore sizes, we provide the longest cushion possible based on the rod size and blind end cpas. Longer cushions are available; for further information, consult factory.
  10. Cushion Needle Adjustment and Ball Check
    The cushion needle adjustment valve and cushion-check ball retainer screw are specifically designed to provide full cushion adjustment.
