Servicing Enerpac hydraulic pumps? The Enerpac 440Z009S7 O-Ring is the genuine replacement part. The O-ring seals the joint between two mating parts, keeping hydraulic oil in and dirt and moisture out. A nicked, flattened or hardened O-ring causes slow leaks and loss of pressure.
When to replace the 440Z009S7
Replace it any time the joint is opened for service, or at the first sign of oil seeping from that joint. Reusing an old O-ring is one of the most common causes of repeat leaks.
