Description
CAT 312-4320 is a genuine backup ring used with a compatible O-ring or sealing element in a pressurized CAT system. The ring supports the primary elastomer seal and helps prevent it from extruding into the clearance gap during high-pressure operation. Exact material, split or solid design, dimensions and installation orientation depend on the seal groove and component group. A complete public CAT record with confirmed specifications was not located. Verify the hydraulic-cylinder or valve group, seal groove, mating O-ring, serial number and CAT SIS before installation.
