Internal sewer branch fitting MAGNAPLAST 67° HTDA 110/50 mm (11420)

MAGNAPLAST internal sewer branch fitting HTDA 67° for 110/50 mm is a polypropylene branch designed to connect a 110 mm main drain with a 50 mm branch at a 67° angle. The compact fitting creates a sealed junction inside sanitary systems, enabling a controlled change of direction and a transition between pipe sizes without requiring additional adapters. It is intended for internal wastewater installations in both residential and light commercial buildings.

Advantages

The polypropylene construction offers chemical resistance and long-term dimensional stability in typical domestic and commercial wastewater conditions. The 67° angle provides a smoother flow path compared with sharper offsets, reducing the risk of blockages where the branch meets the main line. The integrated spigot and socket geometry ensures a tight connection with compatible HT drainage pipes and helps simplify installation and maintenance within confined spaces.

Suitable for

• Internal sanitary stacks and horizontal drain runs in residential buildings
• Branch connections from fixtures such as sinks, toilets or floor drains to a 110 mm main drain
• Repair or retrofit projects that require a compact 110 mm to 50 mm transition
• Light commercial installations with standard HT drainage systems

Key specifications

• Material: polypropylene (PP) suitable for wastewater use
• Angle: 67° branch connection for directional change
• Connection sizes: 110 mm main inlet to 50 mm branch outlet
• Design: compact internal branch fitting for HT drainage systems
• Compatibility: designed for push-fit or socket connections with corresponding HT pipes and seals

How to use

Prepare mating pipe ends by cutting square and deburring to ensure full insertion. Apply compatible seals or lubricants if recommended by the pipe manufacturer and push the 110 mm main pipe and the 50 mm branch pipe into the respective sockets until fully seated. Ensure correct alignment of the branch angle for desired flow direction and check that joint seals are properly engaged. Secure surrounding supports or clips as required by local installation practice and test the system for leaks after assembly.

Usage recommendations

Use with standard HT drainage pipes and compatible rubber seals; avoid exposure to direct sunlight or open flame. For best performance, follow local plumbing codes for slope and support spacing and perform a pressure or water leakage test after installation.
