Drainage Branch 87° MAGNAPLAST HETA 110 mm (model 11980) for internal sewer systems

MAGNAPLAST HETA 87° drainage branch with 110 mm nominal diameter is a plastic fitting intended for internal sewer systems. The fitting allows a branch pipe to be connected to a main run at an 87° angle, providing a near-right-angle junction for wastewater and soil pipe installations inside buildings. It is produced for compatibility with 110 mm drainage pipes and is suitable for gravity drainage applications in domestic and light commercial interiors.

Advantages

The MAGNAPLAST HETA drainage branch is designed for straightforward installation and secure sealing in internal sewer networks. Its 87° geometry enables compact routing where space constraints prevent larger-angle fittings, while the 110 mm interface matches standard drainage pipes for consistent flow capacity. Being manufactured in plastic, the fitting is corrosion-resistant and lightweight, which simplifies handling and reduces the need for additional supports during assembly.

Suitable for

• Connecting a branch pipe to a main drain in residential buildings
• Internal soil and wastewater pipe systems in apartments and houses
• Renovation and new-build sanitary installations with 110 mm pipework
• Gravity-fed drainage runs where an 87° junction is required

Key specifications

• Angle between branch and main run: 87°
• Nominal diameter: 110 mm
• Material: plastic (PVC or similar polymer used for internal drainage)
• Application area: internal sewer systems, soil and wastewater
• Connection type: socketed joint suitable for 110 mm pipes

How to use

Prepare the pipe ends by ensuring they are clean and free of burrs or debris. Insert the branch and main pipe ends into the fitting sockets following manufacturer guidance for insertion depth and alignment to achieve the correct 87° junction. Use the compatible sealing method recommended for the pipe system (rubber ring or solvent-weld where appropriate) and verify that joints are seated evenly. After assembly, check alignment and run a water test to confirm leak-free connections before closing walls or ceilings.

Usage recommendations

During installation, follow local plumbing codes and the pipe system manufacturer’s instructions. Avoid applying excessive mechanical stress to the fitting; provide proper support to connected pipe runs, and ensure access for inspection where required. For long horizontal runs, maintain correct slope for gravity drainage to prevent pooling.
