## Summary description

SiGMA-Li PERTM20T is a compression-style sleeve fitting (tuleja) designed for 20 mm PE-RT piping systems. Manufactured as a pipe connector, it provides a mechanical joint for thermal-plastic PE-RT tubing in heating and potable water installations. Use for connecting, extending or repairing 20 mm PE-RT lines where a secure, compact sleeve connection is required.

## Long description

SiGMA-Li PERTM20T is a compression-style sleeve fitting designed for secure connections in 20 mm PE-RT piping systems. As a compact pipe connector (tuleja), it creates a mechanical joint suitable for heating and potable water installations where a reliable, space-saving sleeve connection is required. The fitting is intended for connecting, extending or repairing 20 mm PE-RT lines and is compatible with standard PE-RT tubing of the same nominal diameter.
Advantages
The fitting provides a mechanical, non-soldered connection method that simplifies installation and reduces the need for specialized tools. Its compression sleeve design ensures a tight seal around 20 mm PE-RT pipe, offering resistance to axial pull-out and minimizing the risk of leaks when installed correctly. The compact form factor allows use in confined spaces and facilitates quick repairs or system modifications without replacing long segments of piping.
Suitable for
Connecting two sections of 20 mm PE-RT tubing
Extending existing 20 mm PE-RT pipe runs
Repairing damaged or leaking segments of 20 mm PE-RT lines
Space-constrained installations where a compact sleeve connector is required
Key specifications
Connection type: compression-style sleeve fitting for PE-RT pipes
Compatible pipe outer diameter: intended for 20 mm PE-RT tubing
Application: suitable for potable water and heating systems using PE-RT
Material: thermoplastic components designed for mechanical pipe joining
Design: compact, inline sleeve (tuleja) connector for straight joints
How to use
Prepare the 20 mm PE-RT pipe ends by cutting them squarely and removing any burrs or debris. Slide the compression sleeve components onto the pipe as specified by the manufacturer's assembly sequence and fully insert the pipe ends into the fitting until they reach the internal stop. Tighten the compression nut or sleeve according to recommended torque or hand-tightening procedure for this type of connector, ensuring an even compressive seal around the pipe. Verify the joint by performing a pressure test or visual inspection to confirm there are no visible leaks before putting the system into regular operation.
Usage recommendations
Use this compression sleeve fitting only with 20 mm PE-RT tubing and follow applicable local codes and standards for potable water and heating installations. Ensure pipe ends are clean and cut square to achieve proper sealing. When in doubt, consult manufacturer installation instructions or a qualified installer to confirm compatibility and to verify torque and testing procedures.
