Wall Elbow SiGMA-Li KZW2012 90° 20 mm (1/2") PP for Plumbing Connections

SiGMA-Li KZW2012 90° wall elbow is a polypropylene (PP) fitting designed for 20 mm (1/2") plumbing connections. It creates a compact right-angle junction between horizontal pipe runs and wall fixtures, suitable for potable water and standard domestic plumbing systems. The elbow's plastic construction offers chemical resistance and low weight, making it practical for recessed or surface-mounted installations where corrosion resistance and ease of handling are required.

Advantages

The polypropylene body provides resistance to corrosion and common household water chemicals while keeping the fitting lightweight. Its 90° angle ensures a predictable change of direction with minimal flow disruption in small-diameter pipework. The compact form factor allows installation within confined spaces behind fixtures or in surface-mounted runs, and the material properties reduce the risk of galvanic interactions compared with metal fittings.

Suitable for

• Potable water supply lines with 20 mm (1/2") pipe diameter
• Domestic and light commercial plumbing systems
• Recessed wall fittings behind sinks, faucets, or fixtures
• Surface-mounted installations where a plastic elbow is preferred

Key specifications

• Angle: 90° elbow
• Material: polypropylene (PP)
• Connection size: 20 mm (1/2")
• Application: potable water and standard plumbing systems
• Design: compact form suitable for recessed or surface-mounted fittings

How to use

Prepare compatible 20 mm pipe ends by cutting squarely and deburring. Fit the elbow according to the chosen joining method for polypropylene pipe systems (for example, push-fit, solvent welding, or fusion if applicable to the system in use) and ensure connections are secure and leak-free. Position the elbow so the 90° turn aligns with the wall fixture and verify clearances for nearby fixtures or mounting surfaces. After installation, perform a pressure test in line with local plumbing standards before restoring full service.

Usage recommendations

Use this polypropylene wall elbow only with pipes and joining methods compatible with PP fittings and rated for potable water if used on drinking water systems. Avoid exposure to prolonged direct sunlight and excessive temperatures beyond the material's rating. Follow local plumbing codes for installation and pressure testing.
