Reducer coupling 50x40 WT Wavin PPR 3051121

Reduction for welded connections – a reliable transition between diameters. Wavin PPR 50x40 socket reduction fitting is a weldable element used to connect polypropylene pipes of different diameters – 50 mm and 40 mm. It is a key component in water supply and heating installations where precise fitting of elements is required. Made of high-quality polypropylene (PP-R), it ensures durability and corrosion resistance, which translates into a long service life of the installation.

Construction and practical application

The construction of the reduction is based on weldable connections (socket), which guarantees the tightness and reliability of the connection. The one-piece design with a simple structure makes installation easy for both professionals and those performing installations themselves. The use of the reduction allows for a smooth transition between different elements of the installation, e.g. when connecting fittings with a smaller diameter to the main pipeline. A Zeta value of 0.55 indicates a relatively small pressure drop at the reduction point, which is important for maintaining optimal system performance.

Key features and benefits

• Durability and resistance: Made of PP-R, resistant to corrosion and mechanical damage – ensures long-term operation without the need for frequent replacement.
• Tight connection: Weldable connections guarantee complete tightness, eliminating the risk of leaks and ensuring safety of use.
• Easy installation: Simple construction facilitates quick and precise installation, reducing investment time.
• Versatility: Designed for use in water supply and heating installations, both in residential and industrial construction.
• Thermal resistance: Withstands continuous operating temperature up to 75°C and maximum working pressure of 20 bar – ensures safe operation under typical conditions.
• With gaskets: The set includes gaskets that further increase the tightness of the connection.
• SDR 6: Indicates the appropriate wall thickness in relation to the outer diameter of the pipe, ensuring mechanical strength and pressure resistance.

Wavin PPR 50x40 WT reduction fitting is a solid element of the Wavin PPR system that will meet the expectations of even the most demanding installers and provide end-users with trouble-free use for many years.
