Reduction tee Detal-met TR40/25/40 PP pipe fitting 40×25×40 mm

Detal-met reduction tee TR40/25/40 is a polypropylene (PP) pipe fitting with dimensions 40×25×40 mm designed to form a reduced-diameter branch in cold-water and drainage systems. The fitting connects three pipes: two straight runs of 40 mm and a central branch of 25 mm. It is intended for non-pressurized drainage, cold potable water distribution where compatible with materials, and domestic irrigation lines. The part is manufactured from durable PP material that resists corrosion and many common chemicals typically present in household and garden systems.

Advantages

The polypropylene construction provides chemical resistance, low weight and long service life in typical indoor and outdoor domestic applications. Its reduction design simplifies transitions between pipe sizes without the need for additional adapters. The smooth internal surface reduces flow resistance and the molded geometry ensures consistent alignment of connected pipes for reliable drainage and flow direction.

Suitable for

• Domestic cold-water distribution where polypropylene fittings are specified
• Non-pressurized drainage and waste systems
• Irrigation lines for gardens or small allotments
• Plumbing runs that require a reduced-diameter branch

Key specifications

• Material: polypropylene (PP)
• Dimensions: 40 × 25 × 40 mm (inlet/branch/outlet nominal diameters)
• Configuration: reduction tee, three-way connection with central reduced branch
• Application temperature range: suitable for cold-water systems (check local codes for max temperature)
• Connection type: socket-fitting for compatible rigid PP pipes

How to use

Prepare pipe ends by cutting square and removing burrs to ensure full insertion into the fitting sockets. Verify pipe compatibility with PP fittings and confirm that system pressure and temperature are within permissible limits for the material. Insert pipes fully into each socket; use the recommended solvent, mechanical jointing method or sealing system specified for the pipe and fitting type if required by the installation practice. Ensure proper alignment and support the pipes near the fitting to avoid stress on the joints.

Usage recommendations

Use this reduction tee in cold-water, irrigation and non-pressurized drainage applications only. Do not expose the fitting to sustained high temperatures or pressures beyond polypropylene’s rated limits; follow local plumbing codes and manufacturer guidance for installation practices and jointing methods.
