Milwaukee Cylinder LH00522-7-70 Rod Seal Kit LH Series

The Milwaukee Cylinder LH00522-7-70 Rod Seal Kit is a field-serviceable replacement that restores rod sealing in Milwaukee LH Series hydraulic cylinders and prevents hydraulic fluid leakage during operation. Designed for industrial and mobile hydraulics, it is commonly installed on hydraulic presses, lifting systems, manufacturing machinery, agricultural equipment, and material handling systems that rely on LH Series cylinders for reliable pressure retention and long service life. Kit contents include rod seals, wipers, O-rings, and backup rings, with seal materials varying by cylinder configuration (Nitrile/NBR, polyurethane, or PTFE), and it uses hydraulic oil as the operating medium. As an OEM replacement maintenance component, it supports cylinder rebuilds, preventive maintenance, and leak repairs across Milwaukee LH Series hydraulic cylinders.
