Parker RG04MAH105 Rod Gland Kit 1 in Rod Hydraulic Cylinder

Product Description

The PARKER RG04MAH105 is a rod gland kit designed for hydraulic cylinder repair and seal replacement. It provides the sealing components necessary to restore proper gland function at the rod end of a cylinder, preventing fluid bypass and maintaining system pressure integrity. This kit is sized for a 1 inch rod diameter and is compatible with bore sizes of 3-1/4 inches, 4 inches, and 5 inches. It is typically installed by hydraulic technicians and industrial maintenance professionals during cylinder rebuild or field repair operations where gland seals have worn, extruded, or failed.

This rod gland kit is suited for hydraulic cylinder repair applications across industrial, mobile, and fluid power systems. The multi-bore compatibility — 3-1/4 inches, 4 inches, and 5 inches — makes it applicable to a range of Parker cylinder configurations using a 1 inch rod. It is appropriate for both shop rebuilds and field service where the cylinder must be disassembled, the gland removed, and sealing elements replaced to bring the unit back to working condition.

Installation Notes

Installation is performed by qualified hydraulic technicians. Before disassembly, fully depressurize and isolate the hydraulic circuit and relieve any residual stored energy in the cylinder. Remove the gland carefully to avoid scoring the rod or bore surface, and inspect both for wear or damage before installing new sealing components. Follow the cylinder manufacturer's service documentation for proper gland torque and reassembly sequence.
