MAGNAPLAST internal sewer elbow 87° dBB 50 mm (model 15550)

The MAGNAPLAST internal sewer elbow 87° dBB 50 mm is a push-fit bend designed for indoor wastewater piping where a change of direction is required. It provides an 87-degree offset for soil and waste lines and is compatible with 50 mm dBB system pipes and fittings. The fitting is intended for gravity drainage applications in residential and commercial buildings, enabling compact routing of drainage runs while maintaining proper flow characteristics.

Advantages

The elbow delivers a near-right-angle change of direction while avoiding the sharper profile of a 90° bend, reducing the risk of blockages and supporting smooth wastewater flow. Its dBB connection ensures a consistent, sealed joint with compatible system components without the need for solvent welding. The 50 mm diameter matches common small-diameter drainage runs, making it suitable for horizontal and vertical installations where space is constrained.

Suitable for

• Indoor soil and waste drainage in residential buildings
• Commercial plumbing installations with 50 mm dBB piping
• Repair or rerouting of existing drainage lines where an 87° offset is needed

Key specifications

• Angle: 87 degrees
• Connection type: push-fit dBB connection compatible with 50 mm system
• Nominal diameter: 50 mm
• Application: gravity drainage for soil and waste lines

How to use

Select the elbow where a change of direction is required in a 50 mm drainage run. Ensure both pipe ends are clean and free of debris before insertion. Push the pipe into the dBB socket until it seats fully, following the manufacturer’s insertion depth guidelines for the system. Check alignment and slope to maintain gravity drainage; support the assembly with suitable brackets or clamps to prevent undue stress on joints.

Usage recommendations

Use the elbow only with compatible 50 mm dBB components and for gravity drainage systems. Verify local plumbing codes for permissible fittings and installation practices. Inspect joints after installation and periodically during maintenance to ensure sealing integrity and unobstructed flow.
