## Summary description

Fitting for PE-RT piping: SiGMA-Li SIGMA LI Kolano wieszak GW 20x1/2 PE-RT (tuleja) is an elbow connector designed to join PE-RT pipe to a 1/2" female thread. Supplied as a tuleja (sleeve) style component, it facilitates secure transitions between polymer tubing and threaded fittings, suitable for heating and potable water installations where PE-RT pipe systems are used.

## Long description

SiGMA-Li SIGMA LI Kolano wieszak GW 20x1/2 PE-RT (tuleja) is an elbow fitting designed to connect PE-RT polymer pipe to a 1/2" female threaded fitting. Supplied in a sleeve (tuleja) configuration, this plumbing elbow enables a secure mechanical transition between PE-RT tubing and conventional threaded components used in heating and potable water systems. The fitting is intended for use where a 90° change of direction is required and where a reliable joint between polymer piping and metal-threaded fixtures is needed.
Advantages
The sleeve-style elbow provides a compact and robust connection method for PE-RT pipe, reducing the need for additional adapters. It ensures a tight interface to threaded fittings while maintaining the corrosion resistance and flexibility advantages of PE-RT systems. The design supports straightforward assembly and integration into existing heating and potable water networks where threaded components are present.
Suitable for
 Connections between PE-RT pipe and 1/2" female threaded valves or fixtures
 Domestic and commercial heating circuits using PE-RT tubing
 Potable water installations requiring reliable polymer-to-thread transitions
 Tight spaces where a 90° elbow is required to change pipe direction
Key specifications
 Pipe compatibility: PE-RT (polyethylene of raised temperature resistance)
 Connection type: sleeve-to-female thread elbow
 Thread size: 1/2" female
 Nominal pipe size: 20 mm external diameter
 Configuration: 90° elbow
 Application: heating systems and potable water networks
How to use
Prepare the PE-RT pipe by cutting squarely and deburring the end. Insert the prepared pipe into the sleeve until it seats fully according to the sleeve depth, then secure the sleeve connection following the manufacturer's recommended method for mechanical fastening or crimping. Thread the 1/2" female end onto the corresponding male threaded fitting and tighten to the required torque, taking care not to over-tighten polymer components. After assembly, perform a pressure test of the system to verify leak-free performance before commissioning.
Usage recommendations
Use appropriate pipe preparation tools and follow local plumbing regulations. Avoid excessive bending near the elbow; observe the minimum bend radius for PE-RT pipe. Where required, apply suitable sealing material on metal threads and verify compatibility with potable water use. Regularly inspect joints after installation, especially after thermal cycling in heating systems.
