Silent-PP HT 90/87.5 sanitary elbow, for low-noise internal drainage, black color 390.424.14.1

Silent-PP Drainage Elbow – Quiet and Reliable Installation

This is a 90-degree elbow from the Silent-PP series, designed for internal drainage systems. Made of polypropylene (PP-MD) in black, it provides effective wastewater drainage while reducing noise. The use of an EPDM rubber gasket guarantees tightness and long-term operation.

The Silent-PP elbow is part of the Geberit system, combining high-quality materials and thoughtful design. It is ideal for both professional installers and end customers who value comfort and peace of mind.

Construction features and application

The elbow has push-fit connections with a nominal diameter of DN 90, which simplifies installation and ensures a secure connection with other system components. The bend angle is 87.5°, allowing for precise adaptation to the existing installation. The wall thickness of the connections (3.1 mm) ensures mechanical strength and resistance to damage.

The application of the Silent-PP elbow includes:

• Wastewater drainage inside buildings – both in residential and public buildings.
• Drainage installations in the ground, located inside the building structure.
• Central vacuum systems in single-family homes (according to manufacturer's recommendations).
• Rainwater drainage pipes (with limitations – check the specifications).

Advantages and benefits for installers and users

• Noise reduction: The Silent-PP series is designed to minimize the sound of flowing wastewater, which translates to comfort in building use.
• Tightness: The EPDM gasket provides reliable sealing of connections, eliminating the risk of leaks and unpleasant odors.
• Durability: PP-MD material is characterized by high resistance to chemicals and mechanical damage, guaranteeing the long service life of the elbow.
• Easy installation: Push-fit connections simplify and speed up the installation process, saving time and labor costs.
• Compatibility: The elbow is part of the comprehensive Geberit Silent-PP system, ensuring full compatibility with other installation elements.
• Temperature stability: The material retains its properties over a wide temperature range (installation from -10°C to +40°C), and low thermal expansion (0.08 mm/(m*K)) minimizes the risk of deformation under the influence of ambient temperature changes.
