Product Overview

The 569-50-85120 PACKING is a genuine Komatsu OEM replacement packing from the 569 prefix series. Packings are sealing components used in hydraulic cylinders, pumps, valves, and other pressurized assemblies — they prevent internal and external fluid leaks while withstanding the pressure, temperature, and speed conditions of hydraulic system operation.

When to Replace

Replace the 569-50-85120 when fluid is leaking at the sealed interface; when the packing material is hard, cracked, or has taken a permanent set; when cuts, nicks, or extrusion damage are visible on the packing lips or body; or whenever the hydraulic component is disassembled for any service — packings must always be replaced during overhaul.

Installation

3. Lubricate the packing with clean hydraulic oil before installation
4. Seat to correct depth and in correct orientation — packings often have directional lips
