## Summary description

SiGMA-Li TR2520 is a polypropylene reducing tee (trójnik) with dimensions 25×20×25 mm designed for connecting three pipes with a reduced middle branch. The fitting is suitable for plumbing and fluid distribution systems where a transition from 25 mm to 20 mm is required. Used in water supply, heating circuits and general piping installations for reliable, corrosion-resistant connections.

## Long description

SiGMA-Li TR2520 polypropylene reducing tee 25×20×25 mm is a plumbing fitting designed to connect three pipes where the center branch has a smaller diameter. Manufactured from polypropylene, the reducing tee provides corrosion resistance and chemical stability for use in cold and hot water distribution, heating circuits, and general piping systems. The 25×20×25 mm configuration enables a smooth transition between pipes of 25 mm and 20 mm diameters without introducing metal components.
Advantages
The polypropylene construction ensures lightweight handling, resistance to corrosion and scale, and compatibility with common plumbing media. The reducing tee design allows a reliable branch connection with minimal flow disturbance at the transition point. Its smooth internal surface reduces pressure loss and sediment accumulation compared with rougher materials.
Suitable for
Domestic cold and hot water distribution
Heating circuit branches and radiator connections
Supply lines in utility and service installations
Non-aggressive chemical transfer in industrial piping
Key specifications
Material: polypropylene (PP)
Configuration: reducing tee with middle branch reduced
Nominal connection sizes: 25 mm × 20 mm × 25 mm
Application: plumbing, heating, fluid distribution systems
How to use
Prepare the pipes by cutting squarely and deburring the ends, then verify diameters match the 25 mm and 20 mm connections. Use the recommended joining method for polypropylene fittings compatible with the system — for push-fit or solvent-weld variants follow the manufacturer’s joining instructions and curing times. Ensure proper alignment of the branch and apply any required support clamps or brackets to prevent stress on the fitting after installation. Pressure-test the system according to local standards before putting it into service.
Usage recommendations
Use SiGMA-Li polypropylene fittings within their rated temperature and pressure limits, avoid exposing the fitting to direct UV for prolonged periods, and store in a dry place. For long-term reliability, combine the reducing tee with compatible polypropylene pipes and fittings and follow applicable plumbing codes during installation.
