Long PP-HT reduction 50x40 sanitary, for internal drainage, grey color 3043907

Sewer reduction PP-HT – reliability and durability in your system

This PP-HT reduction with diameters of 50x40 mm is a key element of sewage systems in residential and commercial buildings. Made of high-quality polypropylene, it provides a reliable connection of pipes with different diameters, enabling efficient drainage of sanitary wastewater. Its gray color makes it easy to identify and aesthetically blends into the installation.

This reduction is part of a comprehensive Wavin internal drainage system, which has been appreciated by installers for years due to its durability and ease of installation. The use of PP HT (high temperature) material guarantees resistance to high temperatures – up to 100°C – which is particularly important in places exposed to hot wastewater. Thanks to this, you can be sure that the installation will operate flawlessly for years.

Construction and application

The long PP-HT reduction connects a 50 mm diameter pipe with a 40 mm diameter pipe using spigot/pipe end and push-fit socket connections. The eccentric model ensures optimal flow and minimizes the risk of blockages. The use of thermoplastic elastomer (TPE) seals guarantees a tight connection, eliminating leaks and unpleasant odors. An additional support collar increases the stability of the reduction in the sewage system.

The PRiK “Good Choice” mark, which distinguishes Wavin PVC internal drainage, confirms high standards of production quality, technology and customer service. This is a guarantee of professionalism and care for the natural environment. This system is also characterized by minimal roughness, which translates into resistance to incrustation (overgrowth) and long-term performance – even up to 50 years!
