PP-R reducing socket - 20/16 1209220004

Pipe diameter reduction in PP-R installations

The PP-R threaded reducing sleeve 20/16 is an indispensable element of the KAN-therm PP system, designed for connecting pipes of different diameters in water supply, heating and cooling installations. The fitting allows for a precise transition from a 20 mm diameter pipe to a 16 mm diameter pipe, ensuring a tight and durable connection. Made of high-quality polypropylene random (PP-R), it guarantees corrosion resistance and long-lasting installation.

Construction and application

The reducing sleeve is characterized by a simple construction, which facilitates its installation. It is intended for direct fusion welding – both from the larger and smaller diameter side – which ensures a uniform and durable connection. This minimizes the risk of leaks and failures. The fitting finds application in 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. It is compatible with pipes and fittings of the KAN-therm PP system, creating a coherent and reliable installation.

Key advantages for professionals and users

• Durability and tightness: Fusion welding provides an inseparable connection, eliminating the risk of leaks and failures in the future.

• Versatility: Can be used in domestic water, central heating and cooling installations – one element for many applications.

• Chemical resistance: Polypropylene random is resistant to many chemical substances, allowing the fitting to be used even in difficult conditions.

• Hygiene: The material is microbiologically and physiologically inert, which is particularly important in drinking water installations.

• Long-term warranty: The KAN-therm PP system is covered by a 10-year warranty (even 15 years in individual construction), which demonstrates the high quality of the product.

• Certificates: It has CSTB, ITB, Lloyds and PZH certificates, confirming compliance with applicable standards and safety of use.

• Easy installation: The simple construction facilitates quick and efficient connection during installation.

Compliance with PN‑EN 15874 ensures high product quality. The maximum operating temperature is 90°C, and the maximum working pressure is 20 bar for cold water, 10 bar for hot water and 6 bar for central heating.

The PP-R threaded reducing sleeve - 20/16 is a solid solution for demanding installers and users who value reliability and durability of heating and water systems.
