Pipe coupling Supratherm PP-R 40 mm, model 2203992

Pipe coupling Supratherm PP-R 40 mm (model 2203992) is a connector for joining two 40 mm polypropylene-random (PP‑R) pipes. The coupling is intended for plumbing and heating installations and provides a corrosion-resistant, durable joint compatible with hot and cold water systems up to 90ºC.

Advantages

The Supratherm PP‑R coupling is lightweight yet offers high impact, abrasion and chemical resistance. Its polypropylene‑random material maintains strength and dimensional stability at service temperatures up to 90ºC, ensuring reliable performance in domestic and light industrial piping systems. The design supports secure fusion welding for leak‑free connections.

Suitable for

• Connecting two 40 mm PP‑R pipes
• Hot and cold water supply systems
• Heating circuits and radiator connections
• Residential and light industrial plumbing installations

How to use

Prepare the pipe ends by cutting them square and cleaning off any debris. Use compatible PP‑R welding equipment (socket fusion or butt fusion) following the welding tool manufacturer’s instructions. Heat the coupling and pipe ends to the specified temperature, insert the pipes to the correct depth, and allow sufficient cooling time to form a permanent joint. Check the joint visually and pressure‑test the system according to local codes after installation.

Usage recommendations

Store fittings in a dry, shaded area away from direct sunlight. Use only certified PP‑R welding tools and follow national plumbing and heating standards for installation and pressure testing. Avoid exposure to solvents and service temperatures above 90ºC.
