Compression Elbow SiGMA-Li GZ 20x1/2 for PE-RT pipes (PERTKZ2012)

The SiGMA-Li Compression Elbow GZ 20x1/2 for PE-RT pipes is a 90° fitting designed to connect 20 mm PE-RT piping to a GZ 1/2 threaded outlet. Intended for plumbing and heating systems, this elbow facilitates a secure directional change while maintaining flow integrity in potable water and underfloor heating circuits. The compression connection for PE-RT ensures a mechanical seal without the need for heat fusion at the joint, simplifying installation and future maintenance.

Advantages

This compression elbow provides a compact 90° turn with a threaded GZ 1/2 male connection and a 20 mm interface suitable for PE-RT pipes. The design supports reliable sealing under typical domestic water and heating pressures and reduces risk of leaks when fitted according to manufacturer guidelines. Its construction is compatible with potable water systems and with common underfloor heating applications that use PE-RT pipework, offering a balance of ease of installation and durable performance.

Suitable for (tasks / use cases)

• Connecting 20 mm PE-RT pipe to a GZ 1/2 threaded fixture or valve
• Changing flow direction by 90° in domestic plumbing systems
• Underfloor heating manifolds and branch connections using PE-RT pipe
• Potable water distribution where mechanical compression fittings are specified

Key specifications

• Elbow angle: 90°
• Pipe connection: compression for 20 mm PE-RT pipe
• Threaded connection: GZ 1/2 (male)
• Intended media: potable water and heating fluids compatible with PE-RT
• Connection type: mechanical compression (no fusion required at the joint)

How to use

Prepare the PE-RT pipe by cutting squarely and deburring the end. Slide the compression nut and insert any supplied ferrule or sleeve onto the pipe as specified by the fitting manufacturer. Push the pipe fully into the compression port until it seats against the stop, then hand-tighten the compression nut onto the elbow body. Use suitable wrenches to tighten to the torque recommended by the fitting maker, taking care not to overtighten metal components. Thread the GZ 1/2 male end into the mating female thread using appropriate thread sealant or tape if required by local codes, then check the assembly for leaks under pressure.

Usage recommendations

Verify compatibility of the fitting with the specific PE-RT pipe brand and wall thickness in use. Follow local plumbing codes for thread sealing and testing; perform a pressure test after installation and inspect for any signs of movement or leakage. When installing in underfloor heating systems, ensure the elbow is positioned to minimize stress on the pipe and allow access for future maintenance.
