MAGNAPLAST low-noise internal sewage elbow 45° UdBB 160 mm (model 146453)

MAGNAPLAST low-noise internal sewage elbow 45° UdBB 160 mm, model 146453, is a 45-degree drainage fitting designed for indoor wastewater systems. The elbow features a low-noise UdBB design and a 160 mm nominal diameter, intended to redirect flow in soil and waste stacks while reducing sound transmission through building drainage. It is suitable for new installations and renovation projects in residential and commercial buildings where quieter drainage operation is required.

Advantages

The UdBB low-noise construction reduces noise generated by moving wastewater and airflow, improving acoustic comfort in inhabited spaces. The 45° angle provides a smooth change of direction that helps maintain flow velocity and reduces risk of blockages compared with sharper bends. The 160 mm diameter matches common soil and waste systems for larger-capacity drainage lines, and the internal design facilitates compact installation inside walls or service shafts.

Suitable for

• Residential soil and waste stacks where noise reduction is desired
• Commercial buildings and public facilities with indoor drainage routes
• Bathroom and kitchen renovation projects requiring compact internal fittings
• Vertical and horizontal transitions inside service shafts and cavities

Key specifications

• Type: Internal sewage elbow, 45° angle
• Design: Low-noise UdBB configuration
• Nominal diameter: 160 mm
• Application area: Indoor drainage for soil and waste systems
• Material characteristics: engineered plastic suitable for wastewater conveyance (non-metallic)
• Installation profile: compact internal fitting for wall cavities and shafts

How to use

Install the MAGNAPLAST 45° elbow as part of the building's indoor drainage network at the point where a change in direction is required. Ensure mating pipe ends are clean and correctly aligned before assembly. Follow the manufacturer's guidelines for joining method (e.g., socket, rubber seal, or solvent joint depending on system type) and ensure proper bedding and support to avoid stress on joints. Verify slope and flow direction after installation and conduct a water-tightness test according to local plumbing codes.

Usage recommendations

For best acoustic performance, combine the elbow with other UdBB low-noise components in the same drainage run and provide adequate insulation of service shafts. Adhere to local building regulations and use compatible pipe materials and seals to ensure long-term leak-free operation.
