MAGNAPLAST plumbing internal sewer branch tee HETA 87° 40 mm

The MAGNAPLAST HETA 87° internal sewer branch tee 40 mm is an injection-moulded drainage fitting intended for internal wastewater and soil pipe connections. Its 87-degree branch angle provides a compact junction between a main run and a branch line, suitable for use in residential and commercial internal drainage systems. The fitting is made to connect three pipes of the same nominal diameter and is designed for retrofit and new-install applications where a short-angle branch is required.

Advantages

This 40 mm branch tee offers a compact geometry that simplifies routing of branch lines in confined spaces. The injection-moulded construction ensures consistent dimensions and smooth internal surfaces that promote reliable flow and reduced risk of blockages. Its standardized nominal diameter allows compatibility with common internal drainage pipes, and the near-right-angle branch facilitates installations where alignment with fixtures or vertical stacks must be achieved without long fittings.

Suitable for

• Connecting branch lines to internal wastewater and soil pipe runs in dwellings
• Retrofit and replacement of compact junctions in bathrooms and kitchens
• Commercial plumbing installations with limited space for pipe routing
• Drainage systems where a short 87° branch is preferred over larger-angle fittings

Key specifications

• Nominal diameter: 40 mm
• Branch angle: 87° (approximately right angle)
• Connection type: three-way branch tee for same-diameter pipe connections
• Manufacturing method: injection moulding
• Application: internal wastewater and soil drainage

How to use

Prepare mating pipe ends by ensuring they are cut square and free of burrs and debris. Align the branch tee so that the branch outlet faces the required direction and insert pipes into the fitting sockets according to the system's jointing method (push-fit, solvent-weld or as specified by the pipe manufacturer). Ensure proper engagement depth and orientation, and support connected pipes to prevent stress on the junction. After assembly, test the drainage run for leaks and correct flow before closing service voids or wall cavities.

Usage recommendations

Use appropriate pipe sealants or jointing methods compatible with the pipe material and the MAGNAPLAST fitting. Allow adequate access for maintenance and inspection, and avoid placing concentrated loads on the fitting. Follow local plumbing codes and manufacturer instructions for solvent welding, sealing, and pressure testing where required.
