One New Aftermarket Replacement Backup Ring for Caterpillar (Cat) Construction Equipment
This aftermarket replacement backup ring replaces Caterpillar (Cat) OEM part number 1476604. Backup rings are used in hydraulic cylinder and valve sealing systems to prevent primary seals from extruding into the clearance gap between mating components under high-pressure conditions. By supporting the primary seal, the backup ring extends seal service life and helps maintain hydraulic system integrity across a wide range of Cat construction equipment applications.
