PP-R reducing socket - 63/40 1209220014

Pipe diameter reduction in PP-R installations

PP-R reducing coupling with dimensions 63/40 mm is an indispensable element in the KAN-therm PP system, allowing connection of pipes with different diameters. The fitting made of high-quality random polypropylene (PP-R) ensures a durable and tight connection in water supply, heating and technological installations. Its design allows direct welding into the socket of the fitting from the larger diameter side, and the smaller diameter is intended for direct connection with the pipe.

Application and characteristic features

The reducing coupling finds wide application in residential and industrial construction, where precision and reliability of connections are required. It is compatible with the KAN-therm PP system, which guarantees full integration with the remaining installation elements. Made of statistical copolymer polypropylene (PP-R type 3), it is characterized by high chemical and mechanical resistance. This makes it suitable for installations exposed to various substances and loads.

• Versatility: Designed for cold water (up to 20 bar), hot water (up to 10 bar) and central heating (up to 6 bar) installations.
• Durability: Made of high-quality material resistant to corrosion and high temperatures (maximum operating temperature: 90°C).
• Safety: It has CSTB, ITB, Lloyds, PZH and ZiK certificates, confirming compliance with safety and hygiene standards.
• Easy installation: Polyfusion welding ensures quick and reliable installation without the need for additional sealants.
• Long warranty: The manufacturer offers a 10-year warranty (even 15 years in individual construction).

Construction and compliance with standards

The reducing coupling meets the requirements of PN‑EN 15874, which proves its high quality and safety. The simple construction facilitates installation, and the precise dimensions ensure a tight connection. The use of PP-R material guarantees microbiological and physiological inertness, which is particularly important in drinking water installations. In addition, this material is characterized by low thermal conductivity, which reduces energy losses in heating systems.
