Adapter Saunier Duval DUVAL ADAPTER 125/80 S0020189629 for flue/vent connection 125x80 mm

Saunier Duval DUVAL ADAPTER 125/80 is a flue and vent connection adapter designed to provide a secure mechanical transition between ducts or pipes with different diameters. Intended for use where a reduction from 125 mm to 80 mm is required, the adapter ensures proper alignment and sealing in exhaust flue, ventilation or chimney systems. The design supports stable connection of components to maintain safe and efficient evacuation of combustion gases or ventilation air.

Advantages

The adapter offers a precise diameter reduction with a fitted profile to minimise air leakage and ensure a tight mechanical join. Manufactured to match Saunier Duval system dimensions, it simplifies retrofits and component replacements by providing consistent fit and alignment. The component's form reduces the need for custom modifications and supports reliable performance in gas boiler exhaust and ventilation installations.

Suitable for

• Connecting flue pipes where a reduction from 125 mm to 80 mm is needed
• Gas boiler exhaust systems and chimneys compatible with Saunier Duval components
• Ventilation ductwork requiring a reliable mechanical transition between differing diameters

Key specifications

• Diameter reduction: from 125 mm to 80 mm
• Application: flue, vent and chimney connections
• Material: metal/plastic composite compatible with standard flue components
• Connection type: slip-fit mechanical adapter for duct alignment
• Use environment: indoor exhaust and ventilation systems

How to use

Position the larger end onto the 125 mm duct and insert the smaller end into the 80 mm pipe, ensuring proper alignment and engagement. Secure the joint according to the installation practices for the specific flue or ventilation system—this may include clamps, screws or sealing tape as required by local codes or manufacturer instructions. Verify that the connection is tight and that the assembled run maintains correct slope and support for safe exhaust flow.

Usage recommendations

Confirm compatibility with the existing flue or ventilation system and follow national regulations and Saunier Duval installation instructions for gas appliance exhausts. Inspect connections after installation for leaks and proper sealing; perform routine checks during boiler service intervals to ensure continued safe operation.
