MAGNAPLAST Magnaplast Kolano 15° internal low-noise sewer elbow 110 mm (model 146420)

MAGNAPLAST Magnaplast Kolano 15° internal low-noise sewer elbow 110 mm is a compact drainage fitting designed for concealed building drainage systems. The 15° angle directs wastewater flow with reduced turbulence and sound transmission compared with sharper bends, making it suitable for installations where noise control and space-saving routing are required. This elbow is intended for connection to 110 mm soil and waste pipes in vertical and horizontal transitions inside structures.

Advantages

The low-noise design lowers sound propagation by smoothing flow direction changes and minimizing internal turbulence. The 15° curvature provides a compact offset that helps avoid obstacles and reduces the need for additional fittings. Constructed for reliable connection to standard 110 mm pipes, the fitting supports stable alignment and leak-resistant joints when installed according to manufacturer guidelines.

Suitable for

• Internal sanitary stacks and soil pipe systems
• Concealed drainage routes in residential and commercial buildings
• Vertical drops and short offsets where noise reduction is desired
• Situations requiring compact routing to avoid structural elements

Key specifications

• Nominal pipe diameter: 110 mm
• Angle: 15° bend for gentle flow redirection
• Application: internal soil and waste drainage
• Function: low-noise (reduced sound transmission) design
• Compatibility: designed for standard 110 mm drainage systems and fittings

How to use

Position the elbow in the drainage run so the 15° offset aligns with the required change of direction. Prepare mating pipe ends by cleaning and deburring if necessary, then insert into the socket or coupling compatible with 110 mm system components. Ensure proper engagement depth and use the recommended sealing method or gasket supplied for the system to maintain a leak-resistant joint. Check alignment and slope to secure correct wastewater flow and perform a pressure or water-tightness test after installation if applicable.

Usage recommendations

Install indoors in accordance with local plumbing codes. Avoid external exposure to UV or direct sunlight unless protected. For optimal noise reduction, combine with other low-noise system components and maintain recommended discharge slopes. If routing around obstacles, prefer gentle offsets and minimize the number of fittings to reduce turbulence and potential blockages.
