Silent-PP HT 90/45 sanitary bend, for low-noise internal drainage, black color 390.422.14.1

Internal drainage elbow – quiet operation and reliable connection

This Silent-PP HT 90/45 elbow, designed for internal drainage systems, provides not only effective wastewater drainage but also noise reduction. Made of high-quality polypropylene (PP-MD), it guarantees durability and corrosion resistance. The 45-degree elbow is an ideal solution for changing the direction of installation, and the push-fit connections facilitate assembly and disassembly.

Design and application

The Silent-PP GTB 45° elbow is an element of the Geberit Silent-PP system, designed with acoustic comfort in mind. The use of an EPDM rubber gasket ensures the tightness of the connections, eliminating the risk of leaks. This product is used in residential and public buildings where noise reduction generated by flowing media is important. It can be used both in new installations and during the modernization of existing ones.

Thanks to the nominal diameter of DN 90, the elbow is suitable for draining wastewater from larger sanitary appliances. The PP-MD material is characterized by high resistance to chemical substances contained in wastewater, which translates into a long service life of the installation. It is worth remembering the installation temperature range of -10 to +40°C to maintain optimal connection properties.
