Chimney Elbow 45° D150 ABX, flue pipe elbow 45 degrees for 150 mm duct

The ABX Chimney Elbow 45° D150 is a 45-degree flue pipe elbow designed for use with 150 mm nominal-diameter chimney ducts. It enables a compact change of direction in a chimney or stovepipe run while preserving the same internal passage diameter, allowing smooth exhaust flow and straightforward integration with compatible 150 mm components. The product is intended for residential heating installations where space constraints or routing requirements call for a fixed-angle directional connection.

Advantages

This elbow maintains the nominal duct diameter to avoid added backpressure and supports consistent draft performance when correctly installed. Its 45° angle allows gentler directional changes compared with sharper offsets, which helps reduce soot accumulation and resistance. The component is suitable for straightforward mechanical connection to other 150 mm flue elements, enabling reliable routing of exhaust gases with a compact footprint.

Suitable for

• Routing stovepipes and exhaust ducts in residential heating systems
• Connecting flue liners or chimney sections where a 45° turn is required
• Situations with limited space that require a compact directional change

Key specifications

• Angle: 45°
• Nominal internal diameter: 150 mm
• Application: flue pipe / chimney elbow for residential heating exhaust
• Function: directional change while maintaining internal passage diameter

How to use

Fit the elbow between compatible 150 mm flue components, ensuring mating ends are clean and free of debris. Align the elbow to achieve the required 45° change in direction and secure connections according to the chimney system manufacturer’s instructions, using the recommended clamps, collars or sealing methods for the specific material. Verify that the final assembly preserves continuous positive slope where required, and check clearances to combustible materials before commissioning the heating appliance.

Usage recommendations

Installations should follow national and local building codes and the appliance manufacturer’s guidelines. Inspect joints for tightness and signs of leakage after initial use and during regular maintenance intervals. Use this elbow only in systems designed for 150 mm nominal flue diameter and suitable operating temperatures.
