The PVC-U backing ring with a diameter of 200 mm is used to create demountable flanged connections in larger pool and process installations. The design allows safe sealing without the need for permanent bonding.
The material resists water treatment chemicals, including chlorine and pH correction products. The flange withstands operating pressures corresponding to the PN10 class typical for PVC-U fittings.
Dimensional compatibility with the DIN standard ensures trouble-free pairing with counterparts from various manufacturers. Suitable uses include the flanged connection of filters, pumps and manifolds of pool circuits.
