Silent-PP HT 90 sanitary expansion joint, for low-noise internal drainage, black color 390.418.14.1

Quiet drainage in your home – Geberit Silent-PP compensating socket

The Silent-PP HT 90 compensating socket is an element of an internal drainage system, designed to reduce noise and compensate for expansion. Made of high-quality polypropylene (PP-MD), it ensures durability and reliable operation. It is a key element of the drainage installation, especially in residential and public buildings, where acoustic comfort is important.

This socket, with a nominal diameter of DN 90, is used to connect drainage pipes, and its construction allows it to absorb stresses resulting from thermal expansion of the material. This minimizes the risk of damage and leaks in the installation. The EPDM rubber gasket guarantees a tight connection.

Construction and application

The socket has a spigot end and a socket end, which facilitates assembly and disassembly. Made of PP-MD (medium density polypropylene), it is characterized by high resistance to chemicals and mechanical damage. Its black color makes it easy to identify in the drainage system. The working length of the connections is 1.5 mm, which ensures a secure seating of the pipes in the socket.

The Silent-PP HT 90 compensating socket is used in sanitary drainage installations, such as draining water from sinks, showers, bathtubs and toilets. It is ideal for use in residential buildings, hotels, hospitals and other facilities where quiet operation of the drainage installation is required.
