MAGNAPLAST external sewage 45° branch KGFA 200/160 mm (model 20380)

MAGNAPLAST external sewage 45° branch KGFA 200/160 mm (model 20380) is a prefabricated sewer fitting designed for connecting a 200 mm main run with a 160 mm branch at a 45° angle in external drainage systems. Manufactured for underground gravity drainage and stormwater conveyance, the branch provides a compact connection that aligns flow direction and reduces hydraulic disruption at the junction between main and lateral pipes.

Advantages

The component offers a consistent 45° branching angle that promotes smooth flow transition and reduces turbulence compared with sharper junctions. Its design simplifies installation in compact trenches and aligns with standard pipe dimensions used in external sewer and rainwater networks. The product's geometry supports efficient gravity drainage and stable hydraulic performance when properly installed in accordance with local standards.

Suitable for

• Underground external sewer systems that combine a 200 mm main with 160 mm laterals
• Stormwater and rainwater networks requiring angled branch connections
• Gravity drainage installations where a compact 45° junction is required
• Replacement or retrofit work on existing external drainage pipe runs

Key specifications

• Main pipe diameter: 200 mm
• Branch pipe diameter: 160 mm
• Branch angle: 45°
• Application: external underground gravity drainage and stormwater conveyance
• Material: durable sewer pipe material suitable for buried installations (polymer-based)
• Connection type: socket/joint compatible with standard external sewer pipes

How to use

Position the 45° branch in the trench so that the main and branch align with the intended pipe runs, ensuring proper orientation of flow. Prepare pipe ends and mating sockets according to manufacturer guidance and local installation standards. Insert pipes into the fitting sockets with appropriate seals and secure joints to achieve watertight connections. Backfill and compact around the fitting following recommended bedding and cover practices to avoid deformation or displacement.

Usage recommendations

Verify compatibility with existing pipe systems and local codes prior to installation. Use proper seals and bedding materials, and follow recommended installation depths to maintain hydraulic performance and long-term stability of the external drainage network.
