MAGNAPLAST internal sewage elbow tee HETA 75/50 mm 87° (model 11940)

MAGNAPLAST HETA internal sewage elbow tee 75/50 mm 87° is a plastic branch fitting designed for compact connections in internal drainage systems. The product provides a reduced branch from a 75 mm main run to a 50 mm branch at an 87° angle, suitable for wastewater and soil pipe installations in residential and commercial buildings. Its shape allows tight installation in vertical or horizontal runs where a near-right-angle reduced tee is needed.

Advantages

The fitting offers a compact profile that minimizes space requirements in confined installation areas while maintaining the necessary hydraulic passage between 75 mm and 50 mm pipes. Injection-molded plastic construction ensures chemical and corrosion resistance typical for internal sewage applications, and the near-90° angle simplifies routing of branch lines. The smooth internal surface promotes flow and reduces risk of sediment accumulation compared with rougher materials.

Suitable for

• Internal wastewater and soil pipe networks in residential buildings
• Commercial or light-industrial drainage where 75 mm mains need a 50 mm branch
• Tight installation spaces requiring a compact reduced tee
• Vertical stacks or horizontal runs with near-right-angle branches

Key specifications

• Main pipe diameter: 75 mm
• Branch pipe diameter: 50 mm
• Branch angle: 87° (near-right angle)
• Material: injection-molded plastic suitable for internal sewage use
• Application: internal wastewater and soil pipe installations

How to use

Install the tee into a prepared 75 mm main run and connect the 50 mm branch pipe at the intended location, ensuring correct alignment for the 87° branch. Follow standard jointing procedures for the pipe system in use: clean and deburr pipe ends, apply appropriate solvent or sealing method if required by the pipe material, and fully insert pipes to the fitting shoulder for a secure connection. Verify slope and orientation for gravity drainage and secure the assembly to structural elements to prevent movement.

Usage recommendations

Use this reduced tee only for internal drainage systems and with compatible plastic sewer pipes of the stated diameters. Check local building codes for required fall, venting and access provisions. For installations with high solids content or where frequent maintenance is expected, consider accessible cleanouts nearby to allow inspection and clearing.
