## Long description

Press-fit elbow SiGMA-Li SIGMA LI Kolano zgrzewane GW 25x1/2 PE-RT is a right-angle molded fitting engineered for PE-RT piping systems. It combines a 25 mm press-fit connection for polymer tubing with a 1/2" female threaded outlet, enabling secure transition between PE-RT supply lines and threaded fixtures or valves. The fitting is suitable for potable water and heating circuits where a compact, reliable elbow with a female thread is required.
Advantages
The fitting offers a press-fit connection that reduces installation time compared with traditional soldered or glued joints and ensures a consistent mechanical seal when installed with compatible tools. Its molded design minimizes potential leak paths and provides dimensional stability under typical service temperatures for PE-RT systems.

How to use
Prepare the PE-RT pipe by cutting squarely and deburring the end. Verify the pipe insertion depth marked for the fitting and insert the tube fully into the press-fit socket.
