## Long description

SpiroFlex duct adapter 60/100 to 80/125 in white is a ventilation transition piece designed to connect round ducts with nominal diameters 60/100 mm to ducts with nominal diameters 80/125 mm. The adapter provides a smooth, airtight coupling that preserves airflow characteristics when converting between two different circular duct sizes. It is intended for use in residential and light commercial HVAC and ventilation systems where a change of duct diameter is required.
Advantages
The adapter delivers a secure mechanical connection and maintains a stable airflow path between mismatched duct sizes. Its coated white finish offers a neutral appearance that integrates with typical ducting and ceiling installations. The product is compact, lightweight, and simple to install, helping to reduce installation time and the need for custom fabrication. The design supports airtight joining to minimize leakage and maintain ventilation efficiency.
Suitable for
 Converting between round ducts in residential ventilation systems
 Connecting different-sized ducts in light commercial HVAC installations
 Retrofit projects where existing ductwork must be adapted to new components
 Areas requiring an airtight transition to maintain ventilation performance
Key specifications
 Input nominal diameters: 60/100 mm (combined round profile)
 Output nominal diameters: 80/125 mm (combined round profile)
 Finish: white coated surface for neutral appearance and basic corrosion protection
 Material type: metal construction suitable for standard ventilation ducts
 Function: provides transition and airtight coupling between two round duct sizes
How to use
Position the larger and smaller duct ends into the corresponding adapter openings and secure them using appropriate clamps, screws, or sealing tape to achieve an airtight joint. Ensure that the adapter is aligned with the airflow direction and that connections are supported to avoid strain on adjacent ductwork. After mechanical fastening, apply approved sealing materials at the joints where required to prevent leakage and preserve system efficiency.
Usage recommendations
Inspect both duct ends for damage or deformation before installation. Use compatible clamps and HVAC sealing tape or mastic rated for ventilation systems. For optimal performance, avoid sharp bends immediately adjacent to the adapter and provide support to prevent sagging of connected duct sections.
