Description
This backing ring flange set provides a strong, reliable bolted connection for PVC pipe systems where durability and ease of assembly are required. The PVC stub flange is supported by a steel backing ring, delivering added mechanical strength while maintaining the corrosion resistance benefits of PVCu.
The design allows the backing ring to rotate independently of the PVC flange, making bolt alignment quicker and easier during installation. Supplied as a complete set including gasket and backing ring, it offers a dependable sealing solution when connecting pipework to valves, pumps, or other flanged equipment. Commonly used across water treatment, chemical handling, manufacturing, and general industrial applications, backing ring flange sets are ideal where repeated assembly or disassembly may be needed without compromising joint integrity.
