PPR Adjustable wallplate mixer connection
The outlet thread is a parallel BSP (G) female thread, so the 1/2" male connectors of a wall-mounted mixer, or other male G fittings, screw straight into it. Because a parallel thread does not seal on its taper, the joint is sealed with a washer or a suitable thread sealant.

Description and application
The PPR adjustable wallplate mixer connection is a PP-R wall fitting with a CW617N brass female thread that connects the hot and cold PPR supply lines to a wall-mounted bath, shower or basin mixer. It is socket-fused to Ø20 or Ø25 PPR pipe on one side and takes the mixer on a 1/2" BSP parallel (G) thread on the other, rated PN25 to EN ISO 15874-3.
The PPR adjustable wallplate mixer connection is the point where a concealed PPR hot and cold water installation meets a wall-mounted mixer. Its wallplate design gives the mixer outlets a fixed position in the wall, and its adjustable construction lets the installer set the outlets to suit the mixer being fitted. The body is PP-R, moulded from prime-grade polypropylene random copolymer (type 3) for reliable fusion with THERMALINO PPR pipe and a long service life. The threaded outlet is a brass insert of CW617N, a grade with a lead content below 2.2%, in line with European norms. The fitting is rated PN25 and conforms to EN ISO 15874-3, with an operating temperature of 70 °C and a maximum temperature of 95 °C, so it carries both the hot and the cold supply. It is available in Ø20 x 1/2" and Ø25 x 1/2", in white, grey and green. This fitting is used in the first-fix pipework of bathrooms, shower rooms and kitchens in houses, apartments and commercial buildings, wherever a mixer is mounted on the wall rather than on the basin or bath. On the pipe side, the connection is joined to PPR pipe by socket fusion, with the welding tool and fusion times used for the matching pipe diameter. On the mixer side, the female 1/2" BSP parallel (G) thread accepts the mixer's male connectors after the wall is tiled. The adjustment range and dimensions are given in the technical data sheet.

Questions
- Can the PPR adjustable wallplate mixer connection carry the hot water supply to a wall-mounted shower mixer in an apartment?
- Yes, the PPR adjustable wallplate mixer connection is designed for both the hot and the cold supply of a wall-mounted mixer. It is rated PN25 to EN ISO 15874-3, with an operating temperature of 70 °C and a maximum temperature of 95 °C. Permissible pressures at specific temperatures and service lives are listed in the technical data sheet.
- How is the PPR adjustable wallplate mixer connection joined to Ø20 or Ø25 PPR pipe during first-fix bathroom pipework?
- The PPR adjustable wallplate mixer connection is joined to the PPR pipe by socket fusion, using a welding tool and fusion times suited to the pipe diameter. It is available in Ø20 x 1/2" and Ø25 x 1/2". The body is PP-R type 3 and fuses reliably with THERMALINO PPR pipe. The mixer is screwed into the brass thread later, after tiling.
- Which thread does the PPR wallplate mixer connection have, and how should the joint to the mixer be sealed?
- The PPR wallplate mixer connection has a 1/2" BSP parallel (G) female thread in a CW617N brass insert, which accepts the mixer's 1/2" male connectors. A parallel thread does not seal on its taper, so the joint is sealed with the mixer's washer or a suitable thread sealant. Overtightening can damage the thread or the fitting.
- Will a wallplate mixer connection hold a wall-mounted bar mixer firmly, rather than leaving it supported only by the pipework?
- Yes, a wallplate mixer connection gives the mixer a fixed anchor point in the wall, so the mixer is not held up by the supply pipes alone. The wallplate is fixed in the wall during first fix, and the outlets are set to suit the mixer. The fixing method and adjustment range are given in the technical data sheet.
- Is the brass insert in the PPR adjustable wallplate mixer connection suitable for drinking water lines in homes?
- The PPR adjustable wallplate mixer connection uses CW617N brass for its threaded insert, a grade with a lead content below 2.2%, in line with European norms. The PP-R body conforms to EN ISO 15874-3, the standard for PP plastic piping systems in hot and cold water installations. Approval for drinking water depends on the national rules where the fitting is installed.
