MAGNAPLAST Kolano 15° internal drainage elbow dBB 110 mm (model 15700)

MAGNAPLAST Kolano 15° internal drainage elbow dBB 110 mm is a 15-degree pipe fitting designed to create a smooth directional change in wastewater runs while maintaining a constant 110 mm diameter. Intended for use in concealed and exposed sanitary installations, the elbow allows compact routing in situations where a shallow angle redirect is required without reducing flow capacity.

Advantages

The elbow provides a gradual 15° change of direction that minimizes turbulence and reduces the risk of blockages compared with abrupt bends. Manufactured for compatibility with dBB 110 mm systems, the component preserves internal diameter for consistent hydraulic performance. Its compact shape saves space in confined installation areas and simplifies alignment when connecting straight pipe sections. The design supports standard solvent-weld or push-fit jointing methods appropriate to the existing system layout.

Suitable for

• Residential wastewater drainage and sanitary stacks
• Commercial and light industrial drainage installations
• Retrofit projects where a slight directional correction is required
• Areas with limited installation depth or tight routing constraints

Key specifications

• Angle: 15 degrees
• Nominal diameter: 110 mm (dBB system)
• Application: internal wastewater/drainage elbow
• Material compatibility: designed for standard plastic drainage systems
• Use environment: sanitary and building drainage systems (indoor)

How to use

Select the elbow in the correct orientation to achieve the required 15° change in direction and ensure pipe ends are clean and free of debris prior to jointing. Fit the elbow to the adjoining 110 mm dBB pipe using the connection method appropriate for the system (push-fit or solvent-weld), following manufacturer guidance for sealing and curing times where applicable. Support the assembly with appropriate brackets or hangers to avoid undue stress on the joint and verify alignment and gradient to maintain proper flow.

Usage recommendations

For reliable performance, inspect connected pipework for compatibility with dBB 110 mm fittings and use recommended sealants or gaskets. Provide adequate access points or inspection chambers in longer runs, and adhere to local plumbing codes and best practices when installing wastewater drainage components.
