Reducer coupling (mufa) Detal-met MR32/20, polypropylene PP, 32×20 mm

Detal-met MR32/20 is a polypropylene (PP) reducer coupling designed to connect pipes with outer diameters of 32 mm and 20 mm. This reducer (mufa) provides a compact, solvent-free connection that creates a reliable transition between two pipe sizes in plumbing and fluid systems. It is suitable for potable water installations, heating circuits, and general plumbing repairs or new installations where a 32×20 mm reduction is required.

Advantages

The polypropylene construction offers chemical resistance and low weight while maintaining dimensional stability. The reducer coupling enables a secure mechanical fit between dissimilar pipe diameters without additional adhesives. Its compact form factor simplifies installation in confined spaces and reduces the need for additional transition fittings.

Suitable for

• Potable water supply lines requiring a 32 mm to 20 mm transition
• Domestic heating and radiator connections where size reduction is necessary
• Plumbing repair work and retrofit installations
• General fluid distribution systems using polypropylene piping

Key specifications

• Material: polypropylene (PP)
• Connection type: reducer coupling (mufa) for joining different diameters
• Pipe compatibility: designed for pipes with outer diameters of 32 mm and 20 mm
• Application: potable water, heating, and general plumbing systems
• Design: compact inline reducer for space-saving installations

How to use

Prepare pipe ends by cutting square and removing burrs, dirt, and grease to ensure a tight fit. Insert the 32 mm and 20 mm pipe ends into the respective sides of the coupling until fully seated. Depending on the system and local practice, secure the connection by following the manufacturer's recommended joining method for polypropylene fittings (such as mechanical push-fit, socket fusion, or compatible solvent/welding techniques if applicable). Verify alignment and check for leaks after pressurizing the system.

Usage recommendations

Use the reducer coupling only with compatible polypropylene pipes and within the temperature and pressure limits of the piping system. Avoid exposure to incompatible chemicals and follow local plumbing codes. Inspect joints after installation and perform a pressure test according to system requirements.
