Product Overview

The OEM Bosch Rexroth R902602322 Backup Ring is a genuine factory-certified anti-extrusion element designed to protect elastomeric seals in heavy-duty hydraulic valves, pumps, and high-pressure components. Precision-molded from a premium, high-hardness material (indicated by the PT/PTFE design series), this structural ring is installed directly into the sealing gland adjacent to an O-ring on its low-pressure side. By filling the clearance gap, it prevents the primary seal from extruding or tearing under intense cyclic pressure spikes, ensuring absolute fluid retention and dramatically extending the service life of internal hydraulic rotating groups and control sub-assemblies.
