## Long description

Concentric flue elbow 45° Ø80/125 mm designed for coaxial boiler flue systems. This component creates a 45-degree change in the combined exhaust and air intake path in Ø80/125 mm concentric ducting, allowing installers to route the flue where straight runs are impractical. Supplied as a pack of two, the elbows are intended for airtight coaxial pipe installations and help maintain alignment and required clearances at wall or roof penetrations.
Advantages
The 45° concentric elbow provides a compact solution for changing flue direction while preserving the concentric geometry of exhaust and intake channels. Its construction supports airtight connections in coaxial systems and simplifies alignment between pipe sections. Supplied in a two-piece pack, it reduces installation time when multiple bends are needed and helps maintain correct clearances without additional adapters.
Suitable for
Redirecting coaxial flue runs for gas boilers with Ø80/125 mm concentric ducts
Wall or roof penetrations where a 45° bend improves routing or clearance
Retrofit or new installations requiring airtight concentric connections
Key specifications
Angle: 45° change of direction
Compatible pipe diameter: concentric Ø80/125 mm
Application: coaxial flue systems combining exhaust and air intake

How to use
Position the elbow between two concentric Ø80/125 mm duct sections at the required junction, ensuring male and female ends engage fully and achieve a sealed fit.

Usage recommendations
Install with compatible concentric pipe sections for Ø80/125 mm systems and follow the boiler manufacturer's guidelines for sealing and support. Inspect joints for airtightness and avoid excessive mechanical stress on the elbow; provide adequate support for adjacent duct runs.
