Reduction Tee PP plumbing fitting Detal-met TRR25X20X25 25×20×25 mm

Reduction tee made of polypropylene (PP) Detal-met TRR25X20X25, dimensions 25×20×25 mm, is a plumbing fitting intended to connect three pipe runs where a reduced branch is required. Manufactured from corrosion-resistant PP, the fitting provides a junction for cold water systems, heating return lines and general pipe network assemblies that need a change of diameter. The compact design and smooth internal passages reduce flow disturbance and facilitate installation into plastic piping systems.

Advantages

The polypropylene construction offers chemical and corrosion resistance and is lightweight compared with metal fittings. The reduction tee provides consistent dimensional accuracy for reliable pipe alignment and leak-tight connections when joined with compatible plastic piping and appropriate joining methods. Its compact 25×20×25 mm layout minimizes space requirements in tight installations while maintaining stable flow characteristics across the junction.

Suitable for

• Cold water distribution and supply lines
• Heating system return lines
• Irrigation and garden watering systems
• Domestic and light commercial pipe network assemblies

Key specifications

• Material: polypropylene (PP)
• Configuration: reduction tee (branch with smaller diameter)
• Dimensions: 25×20×25 mm (main run × branch × main run)
• Application temperature range: suitable for cold water and return lines (verify system limits before use)
• Compatible with: commonly used plastic piping systems of matching diameters when proper joining technique is applied

How to use

Prepare pipe ends by cutting squarely and removing burrs before assembly. Ensure mating pipe diameters match the fitting dimensions and clean contact surfaces. Join the fitting to pipes using the recommended method for polypropylene connections in your system—such as solvent welding, mechanical compression, or heat fusion—following manufacturer guidelines and local regulations. After assembly, perform a pressure test and inspect joints for leaks before putting the system into regular operation.

Usage recommendations

Verify compatibility with the specific plastic piping type and the joining method used in your installation. Avoid exposure to temperatures and pressures beyond the system rating, and follow local plumbing codes for cold water and heating return line installations. Store the fitting away from direct sunlight and prolonged UV exposure to maintain material integrity prior to installation.
