MAGNAPLAST 45° low-noise internal sewer branch (trójnik) 160 mm, model 146465

MAGNAPLAST 45° low-noise internal sewer branch model 146465 is a 160 mm drainage fitting designed for internal wastewater systems. The 45° branch directs flow between pipes while reducing noise transmission through the drainage network. Built for use in residential and commercial sanitary installations, this component supports both vertical and horizontal runs where smooth flow and acoustic performance are required.

Advantages

The low-noise construction minimizes sound propagation from wastewater flow and reduces vibration transfer to adjoining pipework. The 45° angle provides a gentler change of direction compared with a 90° fitting, promoting smoother flow and lowering the risk of flow disturbances. Made to fit 160 mm pipework, the branch offers consistent dimensions for reliable connections and simplifies installation in typical internal drainage layouts.

Suitable for

• Internal sanitary drainage systems in residential buildings
• Commercial and light-industrial wastewater installations
• Vertical stacks and horizontal soil pipe runs where noise reduction is needed
• Retrofit projects and new-build plumbing systems using 160 mm piping

Key specifications

• Nominal diameter: 160 mm
• Branch angle: 45°
• Function: Internal sewer branch for wastewater flow direction
• Acoustic feature: Low-noise design to reduce sound transmission
• Application: Suitable for vertical and horizontal drainage runs

How to use

Install the branch in accordance with standard plumbing practices and local building codes. Ensure pipe ends are clean and free of debris before assembly. Align the 45° branch to the intended flow direction and make a secure joint using the compatible sealing and joining method for the pipe system in use (e.g., solvent weld, rubber ring, or mechanical coupler as appropriate). Verify slope and support of adjacent pipes to maintain flow and avoid stress on the fitting. After installation, inspect joints for proper engagement and test the drainage run for leaks and acoustic performance if required.

Usage recommendations

Use suitable supports and saddles to prevent point loads on the branch and maintain the designed slope. Where improved noise control is needed, combine the low-noise branch with other acoustic measures such as insulated pipework, sound-absorbing mounts, and adequate access for maintenance.
