## Long description

Detal-met MR40/20 is a polypropylene (PP) reducer coupling designed to connect pipes with outer diameters of 40 mm and 20 mm. Intended for plumbing and drainage systems, this fitting creates a reliable transition between different pipe sizes in cold water, waste and sewer lines where PP components are used. The coupling is suitable for both repair work and new installations and is compatible with standard PP pipe systems.
Advantages
The reducer coupling is manufactured from corrosion-resistant polypropylene, offering chemical resilience and long service life in typical household and light-commercial drainage environments. Its smooth internal surface minimises flow resistance and accumulation of debris, while the simple socket design enables quick mechanical joining with compatible pipes. Lightweight construction and dimensional stability ensure easy handling and consistent fit during installation.
Suitable for
Connecting 40 mm to 20 mm PP pipes in drainage and sewer lines
Cold water distribution where PP fittings are specified
Bathroom and kitchen waste plumbing
Repairing or adapting existing PP pipe systems
Key specifications
Material: polypropylene (PP)
Connection type: reducer coupling (socket-to-socket)
Pipe diameters: 40 mm to 20 mm outer diameter
Application: drainage, waste, sewer, cold water systems
Operating environment: indoor and protected outdoor installations
How to use
Ensure both pipe ends are clean, free of burrs and cut squarely. Insert the larger-diameter pipe into the 40 mm socket and the smaller pipe into the 20 mm socket until they reach the stop. For solvent or heat-weld systems follow the compatibility and joining instructions for PP materials used on the job; for mechanical or push-fit installations confirm the jointing method and any sealing elements required by the pipe system. After assembly, check alignment and ensure there are no visible gaps. Perform a leak test according to local plumbing standards before covering or concealing the joint.
Usage recommendations
Use the coupling only with compatible PP pipes of the stated diameters. Avoid exposure to direct sunlight for prolonged periods without UV protection, and follow local codes regarding burial depth and thermal expansion allowances. For systems carrying hot water or aggressive chemicals, verify material suitability before installation.
