PP-R reducing socket - 90/50 1209220018

Pipe diameter reduction in PP-R installations

PP-R reduction coupling with threads 90/50 is an indispensable element in the KAN-therm system, allowing connection of pipes with different diameters. This fitting made of random polypropylene (PP-R) ensures a durable and tight connection, crucial for the safety and reliability of water supply, heating and central heating installations. Its design allows for easy installation by polyfusion welding, which guarantees the strength of the connection for years.

Construction and application

The reduction coupling is designed to connect pipes with a diameter of 90 mm with pipes with a diameter of 50 mm. Its "threaded" design facilitates precise fitting and welding. Made of high-quality random polypropylene (PP-R), it is resistant to corrosion, high temperatures and pressure. Therefore, it is perfect for cold water installations (up to 20 bar), hot water (up to 10 bar) and central heating (up to 6 bar), with a maximum operating temperature of up to 90°C. The fitting has application classes from 1 to 5, which means its versatility and possibility of use in various types of installations.

Why choose a KAN-therm reduction coupling?

• Durability and reliability: Made of high-quality materials, it guarantees long-lasting and trouble-free operation.

• Easy installation: Polyfusion welding is a quick and simple connection method, available to professionals.

• Wide application: Possibility of use in cold water, hot water and central heating installations.

• Safety: Compliance with PN‑EN 15874 standard and certificates (CSTB, ITB, Lloyds, PZH, ZiK) confirm the high quality and safety of the product.

• Warranty: The manufacturer offers a 10-year warranty (even 15 years in individual construction), which demonstrates its confidence in the product.

• Chemical resistance: Random polypropylene is resistant to the action of many chemical substances present in water and heating systems.

• Versatility: The possibility of directly welding a larger diameter into the fitting socket and a smaller diameter directly from the pipe simplifies installation.
