PP-R reducing socket nipple - 40/20 1209220009

Pipe diameter reduction in PP-R installations

PP-R socket reducer with threads 40/20 mm is an indispensable element when connecting polypropylene pipes of different diameters in KAN-therm PP systems. It allows for a smooth transition from a 40 mm diameter pipe to a 20 mm diameter pipe, ensuring a tight and durable connection. The fitting is designed for butt fusion welding, which guarantees a solid and reliable connection of the installation elements.

Application and properties

The reducer socket is made of random polypropylene (PP-R), a material resistant to corrosion, high temperatures and pressure. This makes it ideal for cold water (up to 20 bar), hot water (up to 10 bar) and central heating (up to 6 bar) installations. It can be used in systems with a working temperature of up to 90°C. The fitting has application class 1-5, which means its versatility and possibility of use in various types of installations - from domestic to industrial.

• Durability and safety: Made of high-quality random polypropylene, resistant to mechanical and chemical damage.
• Wide range of applications: Designed for domestic water (cold and hot) and central heating installations.
• Easy installation: Butt fusion welding ensures quick and easy installation without the need for specialized tools other than a welding machine.
• Long-term warranty: The manufacturer offers a 10-year warranty (even 15 years in individual construction), which proves the high quality of the product.
• Certificates: It has CSTB, ITB, Lloyds, PZH and ZiK certificates, confirming compliance with applicable standards and safety standards.

Construction and installation

The reducer socket has a simple construction that facilitates its installation. It is designed for direct welding into the socket of the fitting from the larger diameter side (40 mm), and the smaller diameter (20 mm) is used for direct connection with the pipe. Using the correct butt fusion welding technique is crucial to ensure a tight and durable connection. Remember to maintain proper surface cleanliness before welding and use dedicated KAN-therm PP tools and accessories. Compliance with PN‑EN 15874 standard guarantees high quality workmanship and safety of use.
