MAGNAPLAST Kolano 67° internal sewer elbow dBB 50 mm (model 15530)

MAGNAPLAST Kolano 67° internal sewer elbow dBB 50 mm is a 67-degree drainage fitting designed for indoor waste and sewage piping in 50 mm systems. Manufactured from durable plastic material, this elbow provides a compact directional change for sanitary installations where a non‑standard bend angle is required. The fitting is intended for concealed or exposed internal sewer connections in residential and commercial buildings and integrates with standard 50 mm drainage pipes and couplings.

Advantages

The 67° angle allows precise alignment of waste lines where space or routing constraints prevent the use of standard 45° or 90° bends. The product is lightweight, corrosion-resistant and easy to handle during installation. Its geometry reduces the need for multiple fittings by providing an intermediate angle, which can simplify routing and lower the number of joints. The smooth internal surface supports effective flow and helps reduce accumulation of solids.

Suitable for

• Indoor sewer and waste installations with 50 mm pipe systems
• Residential bathrooms and kitchens
• Commercial sanitary fittings and small drainage branches
• Tight routing situations requiring an intermediate bend angle

Key specifications

• Angle: 67° designed for directional change in drainage lines
• Connection size: nominal 50 mm for compatibility with 50 mm drainage pipes
• Type: internal sewer elbow suitable for internal installations
• Material: durable plastic with smooth internal surface for improved flow
• Installation environment: indoor sanitary and wastewater systems

How to use

Prepare the existing pipe ends by ensuring they are clean, free of debris and cut square. Dry-fit the MAGNAPLAST Kolano 67° to confirm alignment and orientation before final assembly. Use the appropriate solvent, sealant or rubber couplings compatible with the 50 mm drainage system in use, following manufacturer guidance for the piping system. Once positioned and joined, verify the fitting is secure and that the assembled line has the correct slope for gravity drainage.

Usage recommendations

Use this elbow for indoor drainage where a precise intermediate bend is needed to avoid unnecessary joints; ensure compatibility with the system’s joining method and maintain adequate slope to prevent blockages. Avoid exposure to direct sunlight or high external loads and follow local plumbing codes during installation.
