Backup Ring Chamfered 301961 Good Quality WaterJet Cutter Parts

The Backup Ring Chamfered 301961 is a precision-engineered sealing support component designed for high-pressure Waterjet Cutting Systems, intensifier pumps, and on/off valve assemblies. Its main function is to support O-rings or primary seals under extreme pressure conditions, preventing extrusion, deformation, or premature wear during continuous high-pressure operation.

This 301961 chamfered backup ring is manufactured from high-strength polymer material with excellent resistance to compression, chemical exposure, and temperature variations. The chamfered edge design ensures easier installation, smoother seal transitions, and improved alignment within the sealing groove — all contributing to a secure, leak-free system even when operating at pressures exceeding 60,000 psi (4,137 bar).

Fully OEM-compatible with major waterjet brands such as KMT, FLOW, BFT, and WSI, the Backup Ring Chamfered 301961 is an essential part of valve and pump maintenance kits, helping extend the life of primary seals and maintaining stable pressure performance over long service cycles.
