One New Aftermarket Replacement Backup Ring for Caterpillar (Cat) Backhoe Loaders
This backup ring is a hydraulic sealing component used in the lift cylinder group (CYLINDER GP-LIFT) on Caterpillar 400-series backhoe loaders. Positioned alongside O-rings in the cylinder gland groove, it prevents seal extrusion under high hydraulic pressure, extending seal life and maintaining reliable fluid containment during loader and backhoe operation.
