Pipe reducer Supratherm 40/25 PP-R transition coupling

Supratherm PP-R 40/25 pipe reducer is a transition coupling for connecting 40 mm to 25 mm polypropylene-random (PP-R) pipes. The fitting is intended for plumbing and heating systems and provides a leak-resistant joint between different diameter PP-R pipes. PP-R components are lightweight yet offer high impact resistance, wear resistance and chemical resistance, and are suitable for operation at temperatures up to 90°C.

Advantages

The Supratherm PP-R transition coupling combines low weight with durable mechanical and chemical resistance, ensuring reliable connections in domestic and light commercial water supply, heating and HVAC systems. Its design allows secure joining with standard fusion or solvent methods used for PP-R materials.

Suitable for

• Cold and hot water distribution systems
• Domestic and light commercial heating installations
• Air conditioning and HVAC piping
• Repairs and modifications where pipe diameter reduction from 40 mm to 25 mm is required

How to use

Prepare the pipe ends by cutting square and cleaning them of debris. Join the reducer to PP-R pipes using the appropriate fusion welding or solvent-based joining method recommended for PP-R fittings, following manufacturer instructions and applicable plumbing standards. Ensure proper alignment and allow joints to cool or cure fully before applying pressure or temperature load.

Usage recommendations

Use the Supratherm PP-R reducer only with compatible PP-R piping and joining methods. Verify system pressure and temperature limits and follow local codes. For long-term performance, avoid exposure to direct UV and inspect joints after initial operation.
