Static Backup Ring | Check Valve | 0.8125" OD X 0.563" ID | HJ-300735
The HJ-300735 Static Backup Ring is a precision-engineered high-pressure sealing static back up ring designed to protect O-rings and seals from extrusion and deformation in ultra-high-pressure waterjet pump systems operating up to 60,000 PSI (60K).
Installed alongside elastomeric seals, the HJ-300735 Static Backup Ring provides critical reinforcement, ensuring seal stability, pressure containment, and long-term reliability in demanding industrial environments.
Manufactured from high-performance polymer materials (such as PTFE or engineered thermoplastics), the HJ-300735 Static Backup Ring delivers excellent wear resistance, low friction, and superior chemical compatibility, making it ideal for continuous high-pressure waterjet operation.
