Flue Elbow WADEX FLUE ELBOW 450/18O — metal flue elbow for ducting

WADEX FLUE ELBOW 450/18O — metal flue elbow for ducting is a bent duct section engineered to redirect flue gases in ventilation, boiler flue and chimney systems. The component matches a 450 mm nominal diameter and provides an 18° offset within an angled elbow profile to change exhaust direction while maintaining a continuous metal flue path. The fitting is manufactured from sheet metal for durability and thermal tolerance, and is intended for use with compatible 450 mm duct components to create a sealed, mechanically stable transition in straight-to-angled runs.

Advantages

The WADEX flue elbow offers a robust metal construction that withstands high-temperature exhaust gases and resists deformation. Its matched diameter design ensures compatibility with standard 450 mm duct sections and reduces the need for adapters. The elbow profile provides a controlled directional change that helps maintain draft and flow characteristics in flue and ventilation systems. Installation points are designed for straightforward mechanical joining and sealing with common ductwork materials and sealants.

Suitable for

• Redirecting flue gases in boiler and furnace exhaust runs
• Changing direction in ventilation and chimney ducting where a compact elbow is required
• Integration into metal flue systems built from 450 mm diameter components
• Retrofits where an angled transition is needed between straight duct sections

Key specifications

• Nominal diameter: 450 mm
• Elbow angle/offset: 18° within the elbow profile
• Material: sheet metal construction suitable for flue gas temperatures
• Connection type: compatible with matching 450 mm duct components for mechanical joining and sealing
• Application environment: indoor or sheltered outdoor flue and ventilation systems

How to use

Position the WADEX FLUE ELBOW 450/18O between the adjoining 450 mm duct sections at the required change of direction, aligning the mating ends. Secure the joint using appropriate mechanical fasteners and apply a high-temperature flue sealant or gasket where required to ensure a gas-tight connection. Verify alignment and pitch to maintain proper draft; support the elbow and adjacent ducts according to local installation standards to prevent sagging or stress on joints. Perform a pressure or smoke test after installation if local codes require leak verification.

Usage recommendations

Installations should follow local building and safety codes; use heat-resistant sealants and approved fasteners. Ensure the elbow is used only with compatible 450 mm diameter components and inspect periodicallly for corrosion or damage in high-condensation or aggressive environments.
