Silent-PP HT sanitary tee 75x40/87.5, for low-noise internal drainage, black color 390.347.14.1

Internal drainage fitting – quiet operation and reliable connections

This Silent-PP tee is a key element of drainage installations, designed to reduce the noise of flowing media. Made of high-quality polypropylene (PP-MD), it provides durability and corrosion resistance, which is particularly important in internal systems. Its construction, combined with EPDM gaskets, guarantees tightness and minimizes the risk of leaks.

The tee connects three pipes with diameters of 75 mm, 40 mm and 75 mm at an angle of 87.5 degrees. This is an ideal solution for branching drainage installations, allowing connection of additional sanitary devices or drainage of wastewater from different points. The use of PP-MD material ensures high mechanical strength and resistance to chemicals, which translates into a long system life.

Construction and assembly

The Silent-PP tee is characterized by simple assembly thanks to the use of socket connections (muffs). This does not require specialized tools or welding skills, which significantly speeds up the installation process. EPDM gaskets provide a secure and tight connection, eliminating the risk of unwanted odors and leaks. The wall thickness of the connections (2 mm - 2.6 mm) ensures stability and resistance to mechanical loads.

Durable polypropylene (PP-MD) provides resistance to corrosion and mechanical damage. Gaskets made of ethylene-propylene-diene monomer rubber (EDPM) guarantee the tightness and durability of connections. Socket connections (muffs) facilitate quick and easy installation. The 87.5-degree angle allows optimal adaptation to the existing drainage installation. The Silent-PP system has been designed to minimize the noise of flowing media, which increases the comfort of using the building. The tee is ideal for drainage installations in residential, commercial and public buildings. Nominal connection diameters are DN 40 and DN 70, outer pipe diameters are 40 mm and 75 mm respectively, and working connection lengths are: 23 mm, 26 mm and 42 mm, which affects ease of installation in tight spaces.
