Elbow 45° polypropylene (PP) pipe fitting, Detal-met, 40 mm

Detal-met 45° elbow made of polypropylene (PP) for 40 mm pipes is a compact fitting designed to change the direction of flow by 45 degrees in plumbing, drainage and ventilation systems. Constructed from corrosion-resistant polypropylene, this elbow is suitable for cold water, gray water and general drainage applications where chemical resistance, low weight and ease of assembly are important. The fitting is intended for use with 40 mm diameter pipe runs in residential and light commercial installations.

Advantages

The polypropylene construction provides chemical and corrosion resistance while remaining lightweight compared to metal fittings. The 45° angle reduces flow resistance compared with sharper bends and helps maintain smooth drainage. The fitting is easy to handle and install, requiring common plumbing assembly methods for PP components. Its compact form factor conserves space in constrained routing scenarios.

Suitable for

• Household wastewater and gray water drainage
• Ventilation and air routing in drainage assemblies
• Plumbing layouts requiring direction changes with minimal flow disruption
• Light commercial drainage systems

Key specifications

• Material: polypropylene (PP)
• Angle: 45°
• Nominal pipe diameter: 40 mm
• Application temperature range: suitable for cold water and typical room-temperature drainage (not intended for high-temperature hot-water systems)
• Typical use: drainage, gray water and ventilation lines
• Weight: lightweight thermoplastic construction for easier handling

How to use

Prepare pipes by cutting squarely and ensuring ends are clean and free of debris. Insert the corresponding 40 mm pipe ends into the fitting according to the manufacturer’s recommended assembly method for polypropylene components; depending on system type this may involve solvent welding, push-fit connection, or mechanical coupling compatible with PP fittings. Make sure connections are fully seated and aligned to maintain the 45° direction. After assembly, check for leaks by running water through the system at normal operating pressure and inspect joints visually.

Usage recommendations

Use this 45° PP elbow in cold and gray water drainage and ventilation applications. Avoid exposure to sustained high temperatures and aggressive solvents not compatible with polypropylene. Where mechanical support is required, secure piping near fittings to reduce stress on joints and prevent sagging. Follow local plumbing codes and installation practices when integrating this fitting into a system.
