MAGNAPLAST Kolano 30° HTB 40 mm internal drainage elbow (10710)

MAGNAPLAST Kolano 30° HTB 40 mm internal drainage elbow is designed for household wastewater systems where a slight change of direction is required. The fitting provides a 30-degree bend for 40 mm HTB drain pipes and compatible sanitary fittings, allowing compact routing of waste lines inside walls, under floors or behind fixtures. It is intended for gravity drainage of wastewater in bathrooms, kitchens and utility rooms and is compatible with standard 40 mm HTB pipe systems.

Advantages

The 30° elbow offers a smooth directional change with minimal flow restriction, reducing the risk of blockages compared with sharper angles. Its compact dimensions allow installation in confined spaces and behind sanitary units. The component is manufactured to fit standard 40 mm HTB systems, ensuring a reliable connection and leak-free performance when installed correctly. The straightforward geometry simplifies alignment and assembly during renovation or new build projects.

Suitable for

• Connecting 40 mm HTB drain pipes in tight routes behind sinks, basins and toilets
• Changing direction of internal wastewater lines in bathrooms and kitchens
• Routing drains under floors, inside service voids and in cupboards

Key specifications

• Angle: 30° bend for gradual direction change
• Nominal diameter: 40 mm designed for HTB drainage systems
• Application: internal gravity wastewater drainage for domestic use
• Material compatibility: designed to mate with standard HTB pipes and fittings of the same diameter
• Installation environment: suitable for concealed installation inside walls, floors and service spaces

How to use

Select the elbow where a 30° change of direction is required in a 40 mm HTB run. Ensure pipe ends and fitting sockets are clean and free of debris. Push-fit or solvent-weld according to the HTB system instructions and local regulations, checking alignment before finalising the connection. After installation, run water to inspect for leaks and verify that wastewater flows freely through the bend. Access panels or removable covers are recommended in concealed installations to allow future inspection or maintenance.

Usage recommendations

Use this 30° elbow only with compatible 40 mm HTB pipes and fittings; follow manufacturer and local plumbing standards for solvent or push-fit installation methods. Avoid sharp changes in direction immediately adjacent to the elbow to maintain flow efficiency, and provide access for cleaning in longer concealed runs.
