One New Aftermarket Replacement Backup Ring for Caterpillar (Cat) Wheeled Excavators
This aftermarket replacement backup ring (replaces OEM part number 1259695) is a hydraulic sealing component used in the hydraulic cylinders of Caterpillar wheeled excavators. Backup rings work in conjunction with primary O-ring seals to prevent seal extrusion and deformation under high-pressure hydraulic conditions, helping maintain fluid integrity, prevent leaks, and extend the life of the overall sealing system. Common replacement applications include boom, stabilizer, and blade cylinder assemblies.
