Pipe reducer adapter Supratherm 40/20 PP-R – polypropylene pressure fitting

Supratherm PP-R 40/20 pipe reducer adapter is a polypropylene pressure fitting designed to join a 40 mm pipe to a 20 mm pipe. The fitting is lightweight yet offers high impact resistance, wear resistance and chemical resistance. It is suitable for operation at temperatures up to 90ºC and is commonly used in hot and cold water distribution, heating and air conditioning systems where PP‑R pipe systems are applied.

Advantages

The polypropylene construction ensures corrosion resistance and a long service life in plumbing and HVAC applications. Its low weight simplifies handling and installation, while good impact and wear resistance provide reliable performance under typical mechanical stresses. The reducer enables a secure transition between 40 mm and 20 mm pipes in pressurized systems.

Suitable for

• Hot and cold water distribution systems
• Central heating and radiator connections
• Air conditioning and HVAC piping
• Industrial process pipelines with PP‑R systems

How to use

Prepare the PP‑R pipes by cutting squarely and cleaning the insertion ends. Use compatible PP‑R welding or fusion tools according to the pipe system manufacturer’s instructions to join the 40 mm and 20 mm pipes to the reducer. Ensure correct alignment and allow proper cooling time for fusion joints before pressurizing the system.

Usage recommendations

Use the adapter only within the specified temperature range and with PP‑R piping components. Follow local plumbing codes and the Supratherm installation guidelines for fusion welding, pressure testing and system commissioning.
