Silent-PP HT 90x90x90/87.5 double-plane corner fitting, sanitary, for low-noise internal drainage, black color 390.459.14.1

Corner fitting – quiet drainage in your home

This two-plane Silent-PP HT 90x90x90/87.5° corner fitting is a key element of drainage systems in buildings. It is designed to minimize the noise of flowing media, which translates to user comfort, especially in residential and public buildings. Made of polypropylene (PP), it provides durability and corrosion resistance, and its black color makes it easy to identify in the system.

Design and application

This fitting is used to change the flow direction in the drainage system at an angle of 87.5°. Its design based on push-fit socket connections guarantees tightness and ease of installation. It is used in internal drainage systems where reducing the noise level generated by flowing wastewater is important. Thanks to the EPDM gasket, the connections are exceptionally durable and resistant to external factors.

Advantages for the installer and end user

• Noise reduction: The Silent-PP system, thanks to its special wall structure and materials used, effectively dampens flow noise, ensuring peace and quiet in the building.
• Easy installation: Push-fit socket connections allow for quick and easy installation without the need for additional tools or adhesives. This saves time and labor costs for the installer.
• Durability and resistance: Polypropylene (PP) is a material resistant to the action of wastewater, chemicals and corrosion, which guarantees the long life of the system.
• Tightness: EPDM gaskets provide reliable sealing of connections, eliminating the risk of leaks and unpleasant odors.
• Compatibility: The fitting is an element of the Silent-PP system, which ensures full compatibility with other components of this system – pipes, elbows, tees, etc.
• Dimensions: The nominal connection diameter of DN 90 mm provides adequate flow rate for typical sanitary installations. The wall thickness of the connections is 3.1 mm, which affects the mechanical strength of the element.
• Working length: The working length of the connections is from 46 mm to 50 mm, which facilitates installation in tight spaces.

This corner fitting is an investment in the comfort and durability of the drainage installation – both for professionals performing the installation and for end users who value quiet and trouble-free building operation.
