Sitech Plus PP-HT sanitary tee 160x110/45, for low-noise internal drainage, black color 3067764

Low-noise drainage fitting – quiet operation and reliable connections

This Sitech Plus fitting with a diameter of 160x110/45° is a key element in drainage installations in buildings where noise reduction is a priority. Made of polypropylene (PP-HT), it provides a durable and tight connection of pipes, minimizing the sound of flowing water. Its construction, with a 45-degree angle, allows for flexible adaptation to the installation layout.

Construction and practical application

This fitting is designed for Wavin SiTech+ internal drainage systems, but thanks to its standard dimensions and connections, it can also be used with other compatible systems. Made of PP-HT with a stiffness class of SN4, it guarantees resistance to mechanical and chemical loads. It has spigot/socket connections, which facilitate assembly and disassembly. SBR seals provide additional tightness.

• Noise reduction: The Wavin SiTech+ system – and this fitting is part of it – effectively dampens the sound of flowing water, increasing the comfort of using the building.
• Durability and resistance: PP-HT material is characterized by high resistance to chemical corrosion and mechanical damage, which translates into a long service life of the installation.
• Easy installation: Socket and spigot connections facilitate quick and precise assembly, saving installers time.
• Tightness: SBR seals ensure reliable sealing of connections, eliminating the risk of leaks.
• Versatility: Possibility of use with other compatible drainage systems.

Technical specifications and key features

The Sitech Plus fitting is distinguished by a solid construction and precise workmanship. The wall thickness of the pipes is 4.8 mm (connection 1), 3.1 mm (connection 2) and 4.5 mm (connection 3), respectively, which affects the mechanical strength of the element. The maximum working pressure is 0.5 bar, which is sufficient for standard drainage installations in residential and public buildings. It is worth noting the nominal diameters of the connections: DN 100 for all three branches and the outer diameters of the pipes: 160 mm for two connections and 110 mm for the third branch. The working lengths of individual connections are 75 mm, 64 mm and 76 mm, respectively, ensuring stable pipe mounting in the fitting.

This fitting is characterized by an angle of 45° and a circumferential stiffness class of SN4. Made of polypropylene (PP-HT), it has a nominal connection diameter of 1, 2 and 3 equal to DN 100, and the outer pipe diameters are 160 mm (for two connections) and 110 mm (for the third).

This fitting is not just an element connecting pipes – it is an investment in a quiet, durable and trouble-free drainage installation.
