## Long description

Detal-met MR40/25 PP 40×25 mm is a polypropylene pipe reducer coupling designed to connect a 40 mm pipe to a 25 mm pipe. The fitting provides a reliable, corrosion-resistant transition between differing pipe diameters in plumbing and fluid conveyance systems. Constructed from durable PP material, the reducer is lightweight and suitable for use in domestic and light commercial installations where chemical resistance and ease of handling are important.
Advantages
The polypropylene construction ensures chemical and corrosion resistance while keeping the coupling lightweight and easy to install. The stepped internal profile provides a stable mechanical connection between the two diameters, reducing the risk of leaks when installed correctly. The smooth internal surface minimises flow resistance and prevents sediment accumulation, and the material tolerates typical temperatures and fluids encountered in household and light commercial plumbing.
Suitable for
Reducing pipe diameter from 40 mm to 25 mm in water supply systems
Domestic plumbing and drainage applications
Light commercial fluid conveyance where PP fittings are acceptable
Repairing or adapting existing plastic piping networks
Key specifications
Material: polypropylene (PP)
Connection sizes: 40 mm to 25 mm
Type: reducer coupling
Suitable for cold and typical warm water applications (permanent temperature limits of PP)
Lightweight, corrosion-resistant plastic construction
How to use
Select compatible 40 mm and 25 mm pipes with matching outer diameters and clean the pipe ends of debris and burrs before assembly. For push-fit installation, ensure pipes are fully inserted to the correct depth; for solvent or adhesive systems use an appropriate joining method compatible with polypropylene. After assembly, verify alignment and secure any external supports or clamps as needed. Conduct a pressure or leak test according to local plumbing standards before placing the system into regular use.
Usage recommendations
Use the reducer coupling in installations where polypropylene fittings are specified. Avoid exposure to solvents or conditions outside the recommended temperature range for PP. For pressured systems, follow local codes and manufacturer guidance for support spacing and pressure testing to ensure a safe, leak-free installation.
