Reducing Tee SiGMA-Li TR5020 50×20 mm plumbing fitting

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.
