## Long description

SiGMA-Li wall elbow KWW2012 is a 90° polypropylene (PP) connecting fitting designed for 20 mm (1/2") pipe connections. It provides a compact right-angle transition at wall penetrations for domestic plumbing systems and concealed installations. The fitting is intended to maintain flow direction while keeping a low profile at mounting points such as radiator inlets and supply lines.
Advantages
The polypropylene construction ensures chemical and corrosion resistance suitable for typical potable water and heating systems. Its 90° geometry offers a stable, predictable directional change while minimizing space requirements at the wall. As a purpose-made wall elbow, it helps create neat, concealed connections that simplify installation and reduce visible pipework.
Suitable for
 Domestic cold and hot water distribution

 Angle: 90°

How to use
Install the wall elbow by preparing compatible 20 mm (1/2") pipes according to the chosen joining method (socket fusion, push-fit, or adhesive/primer appropriate for PP, depending on the system). Position the elbow at the wall opening so the outlet aligns with the fixture or radiator connection. Secure the elbow and connected pipe per standard plumbing practice, observing required clearances and supports to prevent stress on the joint.
Usage recommendations
Verify compatibility of joining method and system materials before installation. Avoid excessive mechanical load or bending at the connection, and follow local plumbing codes and manufacturer guidance for temperature and pressure limits applicable to polypropylene fittings.
