PPR Wallplate mixer connection strenght

The PPR wallplate mixer connection is a double PP-R fitting that brings the hot and cold water supplies to a wall-mounted bath or shower mixer. Each outlet is socket-fused to PP-R pipe and ends in a 1/2" BSP female brass thread, and a fixed plastic bridge between them keeps the outlets at a set distance so the mixer sits level on the finished wall.

The PPR wallplate mixer connection is a double fitting for the hot and cold supply of a wall-mounted mixer. It has two PP-R bodies, each with a socket-fusion end and a 1/2" BSP parallel (G) female thread, joined by a plastic bridge of standard length. The bridge fixes the distance and height of the two outlets, so the mixer's connectors meet the threads square and the tap sits level on the tiled wall. The body is made from prime-grade polypropylene random copolymer (PP-R, type 3). The threaded inserts are CW617N brass with a lead content below 2.2%, in line with European norms. The fitting is made to EN ISO 15874-3 and rated PN25, with an operating temperature of 70 °C and a maximum of 95 °C, so it carries both the hot and the cold feed. It is available for Ø20 and Ø25 pipe, both with a 1/2" thread, in white, grey and green. On site, the wallplate is socket-fused to the hot and cold PP-R branches at first fix, with the same welding tools used for the rest of the line. It forms full fusion joints with THERMALINO PP-R pipes of matching size. It is set in the wall before plastering or tiling. Once the wall is finished, the mixer's connectors screw into the brass threads. Its usual place is the bath or shower, and it serves any standard mixer that takes separate hot and cold inlets.
