Designed for restoring Enerpac RCH-series hydraulic cylinders to factory performance, this Hydraulic Cylinder Repair Kit includes the seals, o-rings, and wear components needed to service the cylinder rather than replace it. Keeping a repair kit on hand reduces downtime during maintenance cycles on hydraulic pressing, lifting, and pushing applications.
Manufactured by Enerpac, this kit is engineered to match the original tolerances and material specifications of the target cylinder model, supporting a reliable and lasting repair. It is compatible with the RCH121 single-acting hollow-plunger cylinder and is the correct service kit for that unit.
