45° Elbow Internal Drainage MAGNAPLAST 146320 Low Noise Ø50 mm

MAGNAPLAST 45° Elbow Internal Drainage 146320 for Ø50 mm pipe systems is a compact plumbing fitting designed to redirect wastewater at a 45° angle within building drainage runs. Engineered for low-noise operation, this elbow integrates into domestic and light commercial drainage networks to provide a smoother flow path and reduced turbulence compared with sharper-angle fittings. The product is compatible with standard 50 mm drainage connections and common drainage materials used in indoor installations.

Advantages

This 45° internal drainage elbow reduces flow resistance and minimizes noise transmission through the pipe network by smoothing the change of direction. Its compact form allows installation in confined spaces and facilitates more flexible routing of drainage lines. The fitting is designed for straightforward connection with Ø50 mm systems and helps maintain reliable wastewater discharge while limiting splash and vibration.

Suitable for

• Residential wastewater drainage where quiet operation is required
• Apartment and multi-storey building internal drainage runs
• Commercial interiors with limited installation space
• Repairs and retrofits of existing Ø50 mm drainage systems

Key specifications

• Angle: 45° change of direction for internal drainage
• Nominal diameter: 50 mm (compatible with Ø50 mm systems)
• Design: low-noise profile to reduce turbulence and acoustic transmission
• Application: indoor wastewater drainage for residential and light commercial use

How to use

Prepare matching Ø50 mm pipe ends by cleaning and deburring to ensure a secure joint. Insert the pipes into the elbow until full engagement according to the system's installation practice, using the appropriate adhesive or sealing method if required by the piping material. Position the fitting to achieve the required 45° change of direction and support the adjoining pipe runs to prevent strain on the connection. Test the installed run for leaks and ensure proper slope for gravity drainage.

Usage recommendations

Install the elbow in accessible locations where periodic inspection is possible; avoid permanent burial without access. Use compatible adhesives or seals recommended for the pipe material, and ensure correct slope and support to maintain low-noise performance. For installations in multi-storey buildings, consider acoustically rated pipe supports to further reduce sound transmission.
