Product information

Description

The SiGMA-Li welded reducing tee 20x16 PE-RT is a pressure pipe fitting designed for joining a 20 mm main run with a 16 mm branch in plumbing and heating systems. Made from PE-RT material, this reducing tee is intended for hot and cold water distribution and underfloor heating installations. The fitting is produced for welded/heat-fusion connection methods and provides a monolithic, leak-resistant joint when correctly welded to compatible PE-RT pipes.

Advantages

The welded reducing tee offers reliable hydraulic continuity and reduced risk of leaks compared with mechanical compression joints when installed using proper fusion equipment. PE-RT construction provides good thermal stability and flexibility, allowing easier routing and bending during installation. The reducing profile enables a compact branch connection where a transition from a 20 mm main line to a 16 mm service line is required, saving space in manifolds and concealed installations.

Suitable for

  • Hot and cold water distribution systems in residential and commercial buildings
  • Underfloor heating networks where a 20 mm feed must supply 16 mm loops
  • Plumbing risers and concealed installations requiring compact branch connections

Key specifications

  • Main pipe connection diameter: 20 mm
  • Branch pipe connection diameter: 16 mm
  • Material: PE-RT (polyethylene of raised temperature resistance)
  • Connection method: welded/heat-fusion joint
  • Application: potable water and heating circuits
  • Suitable temperature range: suitable for typical domestic hot water and underfloor heating temperatures when used within system design limits

How to use

Prepare pipe ends by cutting square and removing any burrs, then clean and align pipes to the reducing tee. Use appropriate welding or heat-fusion equipment specified for PE-RT to perform the joint according to equipment and system manufacturer instructions. Ensure correct heating time and fusion pressure to obtain a homogeneous weld. After cooling, verify the joint integrity by pressure testing the system in accordance with applicable installation standards and local regulations.

Usage recommendations

Use the SiGMA-Li reducing tee only with compatible PE-RT pipes and approved heat-fusion tools; avoid mechanical fittings on fusion ends. Follow local plumbing codes and manufacturer guidance for maximum operating temperatures and pressures, and perform pressure tests after installation to confirm leak-free joints.
