One New Aftermarket Replacement Back-Up Ring for Komatsu Construction Equipment
This aftermarket replacement back-up ring is a Komatsu Engineering Standard (KES) seal component used in hydraulic systems across a wide range of Komatsu construction equipment. Back-up rings work alongside O-ring seals to prevent extrusion under high-pressure hydraulic conditions, maintaining a reliable seal in cylinders, valves, and other hydraulic assemblies. Keeping these seals in good condition is critical to preventing hydraulic fluid loss and costly downtime on the job site.
