Silent-PP HT 90 sliding coupling, sanitary, for low-noise internal drainage, black color 390.417.14.1

Silent-PP sliding coupling for drainage – quiet and effective installation

The Silent-PP HT 90 sliding coupling is a key element of an internal drainage system, designed to minimize the noise of flowing media. Made of high-quality polypropylene (PP-MD), it provides a durable and tight connection in sanitary installations. Its design allows for easy assembly and disassembly, which is particularly important during servicing or modification of the installation.

Features and application

The coupling is designed for connecting pipes with a nominal diameter of DN 90 (90 mm). Its sliding system allows for compensation of small displacements and irregularities, which facilitates installation in difficult conditions. The use of an EPDM rubber gasket guarantees long-lasting tightness and resistance to sewage. The Silent-PP coupling is used in residential, commercial and public buildings, where a low noise level generated by the drainage installation is important.

Product advantages

• Noise reduction: The Silent-PP system is designed to dampen the sounds of flowing media, which translates to comfort in building use.
• Durability and resistance: PP-MD material is characterized by high resistance to chemical corrosion and mechanical damage, ensuring a long service life of the connection.
• Easy installation: The sliding design facilitates installation and compensates for small pipe displacements, saving time and minimizing the risk of errors.
• Tightness: The EPDM gasket provides a reliable seal for the connection, preventing leaks and unpleasant odors.
• Compatibility: The coupling is compatible with other elements of the Silent-PP system, allowing for the construction of a complete and coherent drainage installation.
• High quality materials: Both the coupling and the gasket are made of high-quality materials, which guarantees reliable operation for a long time.
• Versatility: Possibility of use in various types of sanitary installations – both in new buildings and during the modernization of existing systems.

Construction and parameters

The coupling is made of polypropylene (PP) with a wall thickness of 3.1 mm on both connection side 1 and 2. It has push-fit connections with an outer pipe diameter of 90 mm and a nominal diameter of DN 90. The lack of surface protection of the connections indicates a standard finish, requiring standard installation procedures. The gasket made of EPDM rubber ensures a tight connection without additional sealing agents. The construction of the coupling allows it to be easily moved along the pipe during installation, which facilitates adaptation to specific installation conditions.
