This kit includes all necessary dynamic and static seals required to rebuild the hydraulic cylinder to original equipment specifications. Components typically consist of piston seals, rod seals, wiper rings, wear rings, and O-rings manufactured from high-grade nitrile rubber (NBR), polyurethane (PU), and PTFE materials compatible with mineral-based hydraulic fluids. The kit restores cylinder sealing integrity, preventing internal bypass and external leakage under operating pressures up to 35 MPa. Direct OEM replacement for Genie part number 56757GT.
