## Summary description

Reducer coupling Detal-met 25 x 20 PP-R is a polypropylene (PP-R) pipe fitting designed to connect a 25 mm pipe to a 20 mm pipe. It provides a secure transition between different diameters in plumbing and heating installations, compatible with PP-R systems and suitable for potable water and heating circuits where PP-R fittings are used.

## Long description

Reducer coupling Detal-met 25 x 20 PP-R is a polypropylene (PP-R) pipe fitting designed to connect a 25 mm pipe to a 20 mm pipe. Intended for use in potable water and heating circuits that use PP-R systems, this coupling provides a reliable diameter transition while maintaining the chemical resistance and low thermal conductivity characteristic of polypropylene. The part is suitable for common plumbing and heating installations where material compatibility with PP-R is required.
Advantages
The coupling offers a straightforward means to join different pipe diameters within PP-R systems, allowing secure, leak-resistant joints when installed with recommended heat-fusion or welding methods. Made from polypropylene, it resists corrosion and many common chemicals, and its smooth internal surface reduces flow turbulence and deposit buildup. Its compact design facilitates installation in confined spaces and aligns with standard PP-R pipe dimensions for consistent fit and performance.
Suitable for
Domestic potable water supply lines using PP-R pipes
Heating circuits and radiator connections in PP-R systems
Plumbing installations requiring a reduction from 25 mm to 20 mm
Retrofit or extension works where compatibility with existing PP-R components is needed
Key specifications
Material: polypropylene (PP-R)
Connections: socket ends for 25 mm and 20 mm pipes
Function: reducer coupling (25 → 20 mm)
Typical applications: potable water and heating systems
Design: compact inline reducer suitable for confined spaces
How to use
Install the Detal-met reducer coupling by preparing clean, correctly cut pipe ends and following the heat-fusion or socket-welding procedure recommended for PP-R materials. Ensure pipe ends are free of dirt, burrs, and moisture before joining. Insert each pipe end fully into the corresponding socket, apply the appropriate fusion tool or welding process for the specified time and temperature, then allow joints to cool without movement to achieve full integrity. After cooling, verify alignment and perform a pressure test of the system according to local codes and installation best practices.
Usage recommendations
Use only with compatible PP-R pipes and fittings and follow the manufacturer’s guidelines for fusion temperature and times. Avoid exposing joined assemblies to direct sunlight for prolonged periods and protect joints from mechanical stresses; perform pressure testing after installation to confirm leak-free performance.
