Wall-mounted compression elbow, polyethylene, PN 6 bar, d. 20 x 1/2" (female)

The wall-mounted compression elbow (bend) for HDPE/polyethylene pipes Ø 20 mm with a 1/2″ female thread is a practical solution for reliable water supply connections to draw-off points and valves. The fitting is designed to connect a polyethylene pipe to components with a male thread (tap, adapter, metal pipe, water inlet/outlet assemblies). Thanks to the wall-mount design, the joint can be securely fixed to a wall, resulting in a neat, straight run that is less exposed to accidental loads and pipe kinking.

The compression (clamp) design provides a leak-tight, stable joint without welding and without specialized tools. This is especially useful when installing outdoor water supply systems, seasonal lines, house/bathhouse/summer-kitchen connections, and irrigation points. The PN 6 bar rating matches typical water supply applications where dependable operation under working pressure and system fluctuations is required.

Why this compression elbow is chosen

Fast installation: typically only a wrench is needed—no soldering, glue, or special equipment.

Reliable sealing: the pipe is seated in the body and firmly clamped by the nut.

Convenient wall outlet: easier to create a “clean” wall outlet and connect plumbing/equipment.

Versatile use: enables different line and transition configurations to suit the site.

Compatibility and applications

The fitting is intended for Ø 20 mm polyethylene pipe/hose—a popular size for connecting to take-off points, flexible plumbing runs, and shower systems (including “rain shower” setups—follow your mixer’s requirements).

Quick installation guide

Shut off the main valve and relieve pressure by opening the lowest outlet point.

Measure accurately and cut the pipe square.

Insert the pipe fully into the fitting until it bottoms out.

Tighten the nut: in most cases, about one full turn after initial engagement is enough. Do not overtighten—this can worsen the result.

You get a tidy wall outlet and a leak-tight threaded connection 20 mm → 1/2″ (female) that is easy to service and, if needed, quick to disassemble and reassemble.
