Pack of 3 HydroSure WRAS Approved Compression Nut Ring 20mm

To install a replacement clinching ring, simply unscrew the nut and remove the pipe from the body of the fitting. The old clinching ring will remain on the pipe but, can be prised off and the new clinching ring installed. Before pushing the pipe back into the main body of the compression fitting, make sure the ‘O’-ring is still in place and free from any twists. Continue to install the pipe as normal.

HydroSure compression fittings feature an internal thrust ring that applies pressure to the clinching ring when the nut is sufficiently tightened. As this pressure between the nut and thrust ring is applied, the clinching ring with sharp teeth like edges lock themselves securely into the pipe wall. This combined action is expertly constructed for maximum security and reliability against pipe dislocation from the fitting.  

Each part is manufactured from high-grade polypropylene polymers mechanically tested to conform to standards EN12201-2 for use in potable water systems and in systems that require components to be WRAS approved. The non-metallic construction of materials is suitable for contact with drinking water having met the requirements of BS 6920-1 :2000.
