MAGNAPLAST low-noise internal sewer elbow 87° UdBB 160 mm (model 146457)

MAGNAPLAST low-noise internal sewer elbow 87° UdBB 160 mm is a purpose-built drainage fitting for right-angled changes of direction inside buildings. Designed for connection to 160 mm drainage pipes, this elbow features acoustic insulation properties that reduce sound transmission from wastewater flow, making it suitable for sanitary stacks and internal soil-and-waste systems where noise control is required. The fitting is intended for use in vertical and horizontal internal drainage runs as part of a MAGNAPLAST system.

Advantages

The MAGNAPLAST 87° UdBB elbow combines a compact 87-degree geometry with low-noise design to limit vibration and airborne sound from wastewater flow. Its dimensions match standard 160 mm drainage piping to ensure straightforward assembly, while the UdBB specification indicates integrated acoustic measures that help meet building soundproofing requirements. The unit is made to work within typical internal sewer and soil-and-waste installations.

Suitable for

• Internal sanitary vertical stacks and horizontal branches with 160 mm pipe diameter
• Residential and commercial building drainage systems requiring reduced noise transmission
• Connections between straight runs where a compact 87° change of direction is needed

When it may not be suitable

This elbow is designed specifically for 160 mm internal drainage lines; it is not suitable for systems with different pipe diameters without appropriate adapters. It is intended for gravity drainage in building interiors and is not specified for external buried drainage or pressurised pipeline applications.

Key specifications

• Angle: 87° change of direction
• Nominal connection diameter: 160 mm
• Type: internal sewer elbow for soil-and-waste systems
• Acoustic rating: low-noise (UdBB) design to reduce sound transmission
• Use environment: indoor sanitary/drainage installations

How to use

Install the MAGNAPLAST 87° UdBB elbow as part of the internal drainage network by joining it to compatible 160 mm pipes using the system’s recommended jointing method (socket, seal or adhesive as appropriate to the piping system in use). Ensure correct alignment and slope for gravity drainage and follow local plumbing codes for support spacing and fixation. Verify seals and joints for leak tightness and allow any adhesive or sealant to cure before conducting pressure or functional tests where required.

What to consider before purchase

• Confirm pipe diameter and system compatibility with 160 mm MAGNAPLAST drainage components
• Check whether UdBB low-noise specification meets the building’s acoustic requirements
• Ensure the elbow geometry (87°) fits the available installation space and routing

Usage recommendations

Use the elbow within a complete MAGNAPLAST drainage system or compatible 160 mm piping network, maintain correct fall and supports for reliable gravity flow, and coordinate installation with acoustic insulation measures if meeting building soundproofing standards is required.
