Sitech Plus PP-HT four-way connector 110x50x50/45 straight, sanitary, for low-noise internal drainage, black color 3074217

Internal drainage quadruple fitting – effective connection and noise reduction

This quadruple fitting, made of polypropylene (PP), is a key element of the Sitech Plus internal drainage system. It is used to create branches in the installation, allowing the connection of additional drains. Its construction, combined with the material, ensures not only durability but also reduces the noise of flowing water – particularly important in residential and public buildings. This quadruple fitting is designed to operate with media at temperatures up to 90°C in continuous flow and 95°C in momentary flow.

Design and application

The Sitech Plus quadruple fitting is characterized by a simple design, which facilitates its installation. It has four connections: two for spigot/pipe end and two for socket with a diameter of 50 mm and 110 mm. Thanks to this, it can be easily integrated with other elements of the Sitech Plus system, creating a coherent and efficient installation. The application of this quadruple fitting is wide – it is ideal for residential buildings, apartments, hotels, hospitals and other facilities requiring quiet and reliable internal drainage. Additionally, the reducing model allows for flexible adaptation to various installation configurations.
