This is the genuine Enerpac Piston, part number M45051, used in Enerpac hydraulic cylinders. The piston moves inside a bore under hydraulic pressure, either pumping oil or driving the tool. A scored or worn piston lets oil bypass and reduces output pressure.
When to replace the M45051
Replace it if the piston or its bore is scored, or if the tool loses pressure after the seals have been replaced.
