PPR Wall Plate Elbow with Female Thread

PPR Wall Plate Elbow with Female Thread is a variation on the standard brass insert elbow, built specifically for fixtures that mount directly onto a wall — such as wall-mounted taps, shower mixers, or hose bibs. In addition to the 90° turn and the female-threaded outlet, this fitting includes a flat mounting plate with screw holes, allowing it to be fixed securely to a wall stud or backing board before the wall finish is completed.
This extra fixing point matters because wall-mounted fixtures place more mechanical load on the connection than an in-line fitting does — turning a tap handle or connecting a hose applies torque and pulling force directly to the fitting. Without a secure mounting point, that load would be carried entirely by the fused pipe joint behind the wall, which is not ideal over the long term. The mounting plate lets the fitting be anchored to the structure itself, taking that mechanical load off the plumbing joint.

Application Scenarios & Installation

This fitting is used specifically at wall-mounted fixture locations — a garden tap on an exterior wall, a wall-mounted basin or bath mixer, or a hose bib in a utility area — where the fixture will be screwed directly onto the fitting once the wall finish is complete. It is typically installed during the rough-in stage, well before the wall surface (tile, render or cladding) is applied.
Installers generally fix the mounting plate to a solid backing point — a stud, noggin or blocking — behind the finished wall line, then fuse the PPR socket to the supply pipe before the wall is closed in. Getting the positioning and depth right at this stage matters, since the fitting needs to end up flush with the finished wall surface, ready for the visible fixture to be threaded on once construction is complete.
