U.S.AUrethane Piston

Product Description

 This piston is constructed of oil-resistant polyurethane bonded to a solid metal hub. As fluid pressure increases, the urethane surface of the piston expands against the liner to complete the seal, even in the enlarged diameter of a worn liner bore. This piston has longer life than replacement rubber pistons.
