Backup Ring Assembly 302244 Abrasive WaterJet Pump Parts

The Backup Ring Assembly 302244 is a precision-engineered sealing support component designed for use in high-pressure Waterjet Cutting Systems, intensifier pumps, and on/off valve assemblies. This assembly provides critical structural support to O-rings and primary seals, preventing extrusion and deformation under extreme water pressure conditions. By maintaining correct seal positioning and compression, the 302244 backup ring assembly ensures consistent, leak-free performance during continuous high-pressure operation.

Constructed from high-performance polymer materials with outstanding resistance to compression set, heat, and chemical degradation, the Backup Ring Assembly 302244 is built to withstand pressures up to 60,000 psi (4,137 bar). The assembly features precision-machined surfaces and optimized tolerances to guarantee smooth installation, superior sealing alignment, and long-term reliability.

Fully OEM-compatible with major waterjet brands such as KMT, FLOW, BFT, and WSI, the 302244 backup ring assembly is commonly used in valve and pump maintenance kits to enhance sealing performance and extend the service life of critical waterjet components.
