Silent-PP HT 40/30 sanitary elbow, for low-noise internal drainage, black color 390.121.14.1

Silent-PP Drainage Bend – Quiet and Reliable Installation

This is a Silent-PP bend with a 30-degree angle, designed for internal drainage systems. Made of polypropylene (PP-MD), it ensures durability and corrosion resistance. Its construction, combined with EPDM seals, minimizes the transmission of noise flowing inside the installation, which is particularly important in residential and public buildings. The bend is equipped with push-fit connections, making installation easier and faster.

Construction and application

The Silent-PP bend combines the advantages of traditional fittings with modern acoustic solutions. Its application includes draining wastewater from sinks, showers, bathtubs and other sanitary appliances. With a nominal diameter of DN 40, it is compatible with most standard drainage systems. Made of high-quality polypropylene, it is resistant to the chemicals contained in domestic wastewater.

• Noise reduction: The special design and material dampen the sound of flowing water, providing acoustic comfort.
• Durability and resistance: Polypropylene (PP-MD) is characterized by high resistance to mechanical and chemical damage.
• Easy installation: Push-fit connections allow for quick and easy installation without the need for welding or gluing.
• Tightness: EPDM seals guarantee a tight connection and prevent leaks.
• Compatibility: DN 40 diameter ensures compatibility with most standard drainage systems.
• High-quality materials: Both polypropylene and the EPDM seal ensure long-term use without loss of properties.

The bend has a spigot end and a socket end with a diameter of 40 mm, and the working length of these connections is 9 mm and 10 mm respectively. The seal material is ethylene-propylene-diene monomer rubber (EDPM), which provides reliable sealing for a long time. The use of PP-MD material guarantees high mechanical strength and chemical resistance to substances found in wastewater.
