Static Backup Ring 300727 Good Price Waterjet Parts Supplier

The Static Backup Ring 300727 is a critical support component used alongside O-rings and static seals in ultra-high-pressure waterJet Pump and manifold assemblies. Its main function is to prevent seal extrusion and deformation under extreme pressure, ensuring long-term sealing integrity and system reliability in operations up to 60,000 psi (4,100 bar).

Manufactured from high-strength PTFE (Teflon) or reinforced polymer materials, the 300727 backup ring provides excellent mechanical stability, chemical resistance, and low friction performance. Installed behind an O-ring in a static sealing groove, it supports the seal during pressure cycles, maintaining its correct shape and position—especially under pulsating hydraulic loads common in Waterjet Intensifier Pumps, manifolds, and check valve housings.

The Static Backup Ring 300727 is fully compatible with KMT, FLOW, OMAX, WSI, and BFT waterjet systems, serving as an OEM-equivalent part for both intensifier hydraulic sections and high-pressure water circuits.
