## Summary description

SiGMA-Li TR5020 is a reducing tee plumbing fitting with outlets sized 50 mm and 20 mm. Designed to join and branch pipe runs where a larger main line must be reduced to a smaller branch, it provides a stable mechanical connection for fluid or HVAC systems. Suitable for installation in water supply, heating and drainage pipelines where compatible diameters are required.

## Long description

SiGMA-Li TR5020 50×20 mm reducing tee is a plumbing fitting designed to connect a larger main pipe of 50 mm diameter with a smaller 20 mm branch. Constructed to provide a secure mechanical junction, this reducing tee is intended for use in fluid distribution and HVAC installations where a controlled reduction of diameter is required. The design supports stable flow transition between pipes and accommodates standard joining methods appropriate for the material of the piping system.
Advantages
The reducing tee offers a compact solution for branching and diameter transition with minimal pressure loss when installed correctly. It ensures reliable mechanical connection between main and branch lines and helps maintain system integrity under typical operating conditions. The fitting is compatible with systems that require an abrupt change in pipe size while preserving alignment and flow direction.
Suitable for
Domestic and commercial water supply networks
Heating systems and radiator connections
Drainage and waste pipelines where diameter reduction is needed
HVAC ducting and chilled water distribution when compatible pipe materials are used
Key specifications
Main outlet diameter: 50 mm
Branch outlet diameter: 20 mm
Function: reducing tee for branching and diameter change
Application area: water, heating, drainage and HVAC piping systems
Connection type: designed for standard mechanical joining compatible with pipe material
How to use
Ensure the piping system is depressurized and drained before installation. Measure and cut the pipes to the required lengths, deburr the ends and prepare mating surfaces according to the pipe material's joining method. Align the fitting so the 50 mm opening matches the main line and the 20 mm outlet aligns with the branch direction. Assemble using the recommended joining method for the pipe and fitting materials (for example solvent welding, compression or mechanical coupling), then verify seals and fastening according to system requirements. After installation, perform a pressure test to confirm leak-free operation.
Usage recommendations
Select compatible pipe materials and joining techniques to match the reducing tee and the system working pressure. Avoid using the fitting in systems with chemical exposures or temperatures beyond the material limits. Follow local plumbing codes and standards for sizing, support spacing and testing procedures to ensure durable and safe operation.
