Fitting elbow SiGMA-Li PERTKW2012 – welded GW 20x1/2 for PE-RT piping

Welded elbow SiGMA-Li PERTKW2012 is a pipe fitting designed for PE-RT piping systems. It provides a welded connection to PE-RT pipes and features a female threaded connection sized 20x1/2 to accept standard 1/2" male threaded components. The fitting is intended for redirecting flow and creating compact angled transitions between PE-RT lines and threaded devices in heating and plumbing installations. The construction is suitable for both professional installers and experienced DIY users who require a reliable threaded interface to PE-RT systems.

Advantages

This welded elbow combines a secure welded joint for PE-RT piping with a standardized female thread, enabling a tight mechanical connection to valves, radiators, manifolds or other threaded components. The design minimizes the need for additional adapters, reduces potential leak points compared with multiple joint assemblies, and allows a compact installation in confined spaces. Materials and welding method are chosen to maintain long-term sealing and dimensional stability under typical service temperatures for PE-RT systems.

Suitable for

• Connecting PE-RT pipes to 1/2" male threaded fittings
• Redirecting flow in heating circuits and potable water installations
• Compact installations where an angled transition to a threaded device is required
• Professional plumbing and heating contractors as well as competent DIY installations

Key specifications

• Connection type: welded joint for PE-RT on one end and female thread on the other
• Thread size: 20x1/2 (female)
• Application: heating systems, plumbing and potable water circuits using PE-RT pipe
• Function: 90-degree elbow for redirecting flow
• Compatibility: designed to interface with PE-RT piping materials

How to use

Prepare the PE-RT pipe end according to the welding procedure recommended for the piping system, ensuring a clean, square cut and proper insertion depth. Perform the welding process with the appropriate butt or socket welding equipment specified for PE-RT materials to form a durable joint. After the welded connection has cooled and been inspected, screw the male threaded component into the female 20x1/2 thread using suitable sealing method for the mating part if required (for example, PTFE tape on the male thread where allowed). Check the assembly for alignment and pressure integrity before placing the section into service.
