Pipe elbow 90° PP 40 mm, Detal-met KOLN90/40

Detal-met pipe elbow 90° PP 40 mm is a right-angle plumbing fitting made of polypropylene (PP) designed to connect two straight sections of PP pipe with a nominal diameter of 40 mm. The fitting is intended for plumbing and drainage systems in residential and light commercial installations where a corrosion-resistant, lightweight connection is required. Its 90° bend enables compact directional changes while maintaining flow integrity in wastewater and drainage lines.

Advantages

The polypropylene construction provides chemical resistance, low weight and resistance to corrosion compared with metal fittings. The smooth internal surface reduces the risk of blockages and supports consistent flow. The standardized 40 mm nominal size ensures compatibility with common PP piping systems, and the 90° geometry allows reliable directional changes without special tools or complex installation procedures.

Suitable for

• Household drainage and wastewater lines
• Sinks, washbasins and shower drain connections
• Light commercial sanitary installations
• Repair or retrofit of existing polypropylene piping systems

Key specifications

• Material: polypropylene (PP)
• Angle: 90°
• Nominal diameter: 40 mm
• Application: plumbing and drainage
• Surface: smooth internal bore to reduce deposits
• Weight: lightweight construction for easy handling

How to use

Prepare pipe ends by cutting square and deburring to ensure full insertion and a tight fit. Push the PP pipes into the elbow socket according to the connection type used in your system (socket fusion, solvent-weld, or push-fit as applicable) and follow the pipe system manufacturer’s instructions for secure joining. Verify alignment at the 90° junction and allow any required cooling or curing time if thermal fusion or solvent methods are used. After installation, test the line for leaks using water or an appropriate test medium at working pressure.

Usage recommendations

Use in systems designed for PP fittings and observe maximum temperature and pressure limits for polypropylene components. Avoid exposure to open flame and strong solvents not compatible with PP. Regularly inspect joints after installation to ensure leak-free operation, especially in concealed or hard-to-access areas.
