One New Aftermarket Replacement Ring Backup for Caterpillar (Cat) Excavators, Track-Type Tractors, and Pipelayers
This backup ring (part number 964275, also referenced as 0964275) is used in high-pressure sealing applications on Caterpillar equipment. Backup rings prevent seal extrusion under high-pressure conditions and help protect the overall sealing system from pressure surges, making them a critical component in hydraulic and drivetrain assemblies including the undercarriage track adjuster and recoil group.
