Reducing PP Coupling Detal-met MR40/32 40×32 mm

Reducing polypropylene (PP) coupling Detal-met MR40/32 40×32 mm is a compact reducing fitting designed to join pipelines with different outer diameters. Manufactured from molded polypropylene, it delivers chemical resistance and dimensional stability suitable for potable water systems, irrigation networks and general plumbing. The socket ends accept mechanical connections or solvent-based joining methods, providing a practical solution for transitions between 40 mm and 32 mm pipes in pressure and gravity installations.

Advantages

The polypropylene construction offers corrosion and chemical resistance while remaining lightweight and easy to handle. Molded sockets ensure consistent wall thickness and reliable sealing when properly joined. The reducing profile minimizes flow disturbance at the transition and simplifies retrofit or new-install work by eliminating the need for multiple adapters. Its compact dimensions make it suitable for installations with limited space.

Suitable for

• Cold and hot water distribution systems
• Irrigation and landscape watering networks
• Domestic and light commercial plumbing connections
• Repair or modification of existing polypropylene pipe runs

Key specifications

• Material: polypropylene (PP)
• Connection type: socket coupling for solvent or mechanical joining
• Nominal diameters: 40 mm to 32 mm
• Configuration: concentric reducing coupling
• Suitable media: potable water, non-aggressive liquids
• Operating temperature: suitable for cold and typical hot water service (refer to system parameters)

How to use

Prepare pipe ends by cutting square and removing burrs, then clean and degrease the surfaces to be joined. For solvent-based joining, apply the appropriate polypropylene primer and solvent cement following the cement manufacturer’s instructions, insert the pipes fully into the sockets and allow adequate curing time before pressurizing. For mechanical connections, use compatible clamps or compression fittings intended for PP sockets, ensuring even tightening and proper sealing. Follow the piping system’s design pressure and temperature limits during installation.

Usage recommendations

Verify compatibility of joining materials and adhesives with polypropylene. Do not exceed the recommended operating temperature and pressure for the overall piping system. When used in hot water systems, allow for thermal expansion and secure the pipeline to prevent stress at the coupling. Inspect joints after initial pressurization and periodically during service.
