The PVC backing ring d125 is a robust fitting for demountable flanged connection of pipework with a diameter of 125 mm. The rotating PVC-U collar slides onto the socket or pipe and allows tightening with bolts to any d125 flange counterpart.
The d125 size is typical for the trunk distribution of aquaparks, swimming baths or industrial circulation systems with high flows. The PVC-U material is chemically resistant to chlorine, acids and disinfection products in pool water.
The backing ring allows easy replacement of components without the need to intervene in the pipe route. The standard bolt circle drilling ensures compatibility with the flange sockets of pumps, filters and valves of dimension d125.
