MAGNAPLAST Kolano 67° low-noise internal drainage elbow UdBB 110 mm

MAGNAPLAST Kolano 67° low-noise internal drainage elbow UdBB 110 mm is a compact drainage fitting designed for building sanitary and wastewater systems. The 67-degree bend redirects wastewater flow in internal stacks and branch lines while the low-noise construction reduces sound transmission from flowing water. The UdBB design provides a space-efficient angle suitable for installations where routing constraints or renovation requirements demand a compact solution.

Advantages

The elbow combines a 67° geometry with sound-damping features to limit noise transfer through drain piping. Its internal design supports smooth flow transition and reduces turbulence at the change of direction. The compact form factor allows installation in confined shafts and behind fixtures without extensive rework. Material choice and production tolerances ensure consistent fit with 110 mm drainage systems and reliable long-term performance in sanitary applications.

Suitable for

• Internal sewer stacks and vertical risers in multi-storey buildings
• Branch connections to main stacks where a compact angle is required
• Renovation projects with limited space for new pipe routing
• Noise-sensitive environments such as apartments, hotels, and offices

Key specifications

• Nominal pipe diameter: 110 mm
• Bend angle: 67 degrees
• Design type: low-noise internal drainage elbow (UdBB)
• Application: sanitary and wastewater drainage systems
• Compatible with standard 110 mm drainage fittings and seals

How to use

Position the elbow within the drainage run where a 67° change of direction is required. Ensure mating pipe ends and seals are clean and free of debris before assembly. Install the fitting in accordance with local plumbing codes and the system manufacturer's recommendations, providing correct alignment and support to avoid stress on joints. Check for proper slope and bearing to maintain gravity drainage and minimize standing water.

Usage recommendations

For best acoustic performance, combine the MAGNAPLAST low-noise elbow with other low-noise fittings and maintain continuous support and insulation of drain runs. During renovation, verify available space and routing to ensure the 67° elbow provides the required clearance and connection angles.
