Flue Pipe Reducer Almeva STARR DN60/80 UV‑stable Black

The Almeva STARR DN60/80 flue pipe reducer in UV-stable black is a transition fitting designed to connect DN60 to DN80 ducting in ventilation and flue systems. Constructed from weather-resistant material with UV stabilisation, the reducer preserves sealing and airflow when adapting between different pipe diameters. The compact, cylindrical design supports installation on chimneys, stove flues, ventilation ducts and retrofit projects where a reliable diameter change is required.

Advantages

The reducer provides a secure and leak-resistant transition between DN60 and DN80 pipes while resisting outdoor UV exposure. Its UV-stable material limits degradation and discoloration when used externally. The simple geometry facilitates alignment and sealing, and the component is compatible with common rigid flue and ventilation systems that use standard nominal diameters.

Suitable for

• Connecting stove flues and chimney sections with differing diameters
• Adapting ventilation ducts during retrofit and repair work
• Outdoor flue installations exposed to sunlight
• Temporary or permanent transitions in exhaust or venting systems

Key specifications

• Nominal connection sizes: DN60 to DN80 transition
• Colour: black (UV-stable)
• Material: UV‑stabilised, weather-resistant polymer
• Shape: cylindrical reducer for concentric alignment
• Application environment: indoor and outdoor use

How to use

Align the larger DN80 pipe and the smaller DN60 pipe concentrically before inserting the reducer. Ensure mating pipe ends are clean and free of debris; apply appropriate high-temperature sealant or gasket material where required by the system specifications. Slide the reducer into place until fully seated and secure any clamps, bands or mechanical fasteners recommended for the specific ducting system. Verify the joint for correct alignment and sealing after installation and perform a smoke or leak test if applicable.

Usage recommendations

Use the reducer only within the recommended temperature and pressure ranges of the overall flue or ventilation system. For outdoor installations, periodically inspect the UV-stable surface for physical damage or seal deterioration and replace the fitting if signs of cracking or deformation appear. When connecting combustion appliance flues, follow local codes and manufacturer instructions to maintain safe exhaust performance.
