One New Aftermarket Replacement Back-Up Ring for Komatsu Equipment
This aftermarket replacement back-up ring replaces Komatsu OEM part number 07001-02021. Part of Komatsu's standardized KES (Komatsu Engineering Standard) seal series, back-up rings in this family are used throughout Komatsu hydraulic systems to prevent O-ring extrusion under pressure in cylinders, valves, and other hydraulic components across a wide range of Komatsu construction, excavation, and material-handling equipment. Because this seal series is used as a component in many different hydraulic seal kits and assemblies, specific machine fitment varies. Verify fitment using your equipment's model number and serial number before ordering.
Compatible Models
Komatsu: This back-up ring is used across multiple Komatsu equipment lines including excavators, forklifts, bulldozers, wheel loaders, and motor graders. Consult your Komatsu parts manual or seal kit breakdown using your model and serial number to confirm application.
