## Long description

SiGMA-Li PERTK9020T — PE-RT 20 mm x 90° elbow with sleeve is a compact fitting designed for use in PE-RT piping systems. It provides a right-angle change of direction for 20 mm polyethylene of raised temperature (PE-RT) tubing and includes a sleeve to enable a secure mechanical or thermal joint. The fitting is intended for plumbing and underfloor heating applications where a reliable, space-efficient elbow connection is required.
Advantages
This 90° elbow offers a compact footprint and predictable flow characteristics appropriate for low- to medium-pressure domestic and light commercial systems. The included sleeve simplifies joint assembly and improves connection security, reducing the risk of leaks when installed according to recommended procedures. The product is compatible with standard 20 mm PE-RT pipe, allowing straightforward integration into existing PE-RT layouts for potable water and heating circuits.
Suitable for
Connecting and redirecting 20 mm PE-RT piping in underfloor heating systems
Domestic potable water supply lines where a compact elbow is required
Light commercial plumbing installations with PE-RT tubing
Key specifications
Material type: PE-RT compatible fitting
Pipe diameter compatibility: 20 mm
Angle: 90° elbow
Includes: assembly sleeve for secure jointing
Application: heating and potable water systems
How to use
Prepare the PE-RT pipe by cutting squarely and deburring the end to ensure a smooth insertion. Slide the supplied sleeve onto the pipe if required by the chosen jointing technique, then insert the pipe fully into the elbow until it seats. Complete the joint according to the connection method specified for the system—mechanical compression, push-fit, or heat fusion—ensuring proper positioning and engagement. Verify the joint after assembly and perform a pressure test in line with local installation regulations to confirm watertightness and system integrity.
Usage recommendations
Use appropriate tools to achieve clean pipe ends and follow manufacturer and local plumbing codes for joint assembly and testing. Avoid excessive bending near the elbow to prevent stress on the joint. For installations involving potable water or heated circuits, ensure that the PE-RT piping and fittings are compatible with system temperature and pressure specifications.
