Reducer coupling 110x75 WT Wavin PPR 3051131

Water supply installation reducing coupling

This Wavin PPR 110x75 WT reducing coupling is a reliable solution for connecting polypropylene (PP-R) pipes of different diameters in water supply systems. It allows a transition from a 110 mm diameter pipe to a 75 mm diameter pipe, ensuring a tight and durable connection. It is a key element in the construction or modernization of installations where pipe diameter adjustment is required.

Design and application

The reduction is made of high-quality polypropylene (PP-R), which guarantees corrosion resistance and long-term operation. Its simple, one-piece design facilitates assembly, and the weldable socket ensures a secure connection with the pipes. The use of a reducing coupling allows for flexible installation design and adaptation to specific conditions. Thanks to the nominal connection diameter of 2 DN 110 and connection 1 DN 75, it enables precise adjustment of installation elements.

Advantages and product features

• Durability and reliability: Made of PP-R ensures corrosion resistance and long life.
• Tightness: Weldable connection guarantees no leaks and safe use.
• Easy installation: Simple design makes installation easy, both for professionals and experienced DIY enthusiasts.
• Versatility: Designed for water supply systems, ideal for use in residential and commercial buildings.
• Pressure resistance: The maximum working pressure at 20°C is 20 bar, ensuring safe operation under standard conditions.
• High material quality: PP-R is characterized by good chemical and mechanical resistance.
• With gaskets: Included gaskets further increase the tightness of the connection.
• SDR 6 ratio: Determines the ratio of the outer diameter of the pipe to its wall thickness, affecting mechanical strength. In this case, SDR 6 indicates an appropriate wall thickness for the given working pressure.
• Zeta value 0.55: A parameter taken into account when calculating the hydraulic calculations of the installation, affecting the pressure loss of the flowing water.

The length of the reduction is 92 mm, and the wall thickness of the connections is 19 mm (connection 1) and 12.5 mm (connection 2), respectively. These dimensions ensure a stable and secure connection of pipes of different diameters. The white color makes it easy to identify the element in the installation.
