MAGNAPLAST plumbing branch tee HETA 75/50 mm 67° internal sewage fitting (11740)

MAGNAPLAST HETA 75/50 mm branch tee is a 67° internal sewage fitting intended for indoor wastewater and soil pipe systems. The fitting connects a 75 mm main run with a 50 mm branch, providing a compact junction that accommodates a directional change while keeping flow characteristics appropriate for residential and commercial drainage installations. Designed for integration into vertical or horizontal runs, this branch tee supports standard plastic piping layouts where a reduced-diameter branch is required.

Advantages

The branch tee combines a smooth internal profile and a fixed 67° branch angle to reduce turbulence at the junction and support reliable flow from the branch into the main line. Its two-diameter configuration (75 mm main to 50 mm branch) allows easy transition between different pipe sizes without additional adapters. The internal design is suitable for concealed installation inside walls or service voids and is compatible with typical solvent-weld or push-fit connections used in indoor drainage systems.

Suitable for

• Indoor wastewater and soil pipe systems in residential buildings
• Commercial drainage where a reduced-diameter branch is needed
• Connecting vertical stacks to horizontal drainage runs
• Renovation projects requiring junctions within service cavities or behind fixtures

Key specifications

• Main outlet diameter: 75 mm
• Branch outlet diameter: 50 mm
• Branch angle: 67° (internal)
• Application: indoor wastewater / soil drainage
• Installation position: suitable for vertical and horizontal runs

How to use

Position the MAGNAPLAST HETA branch tee where the branch will join the main run, ensuring correct alignment for the 67° branch angle. Prepare pipe ends according to the system’s connection method (cut square, deburr, and clean for solvent-weld; ensure proper insertion depth for push-fit). Connect the 75 mm main and the 50 mm branch to their respective sockets, following the pipe manufacturer’s instructions for sealing and jointing. Verify slope and alignment for gravity drainage, and support adjacent pipework to prevent strain on the fitting.

Usage recommendations

Use the branch tee only within indoor wastewater and soil systems; avoid exposure to direct sunlight or external mechanical loads. Confirm compatibility with the pipe material and joining method in your installation. During commissioning, inspect joints for leaks and ensure adequate gradient for self-cleansing flow.
