## Summary description

SpiroFlex adapter 80/110–80/125 TWK in white is a duct transition fitting that connects 80/110 mm round ducts to 80/125 mm round ducts. Manufactured by SpiroFlex, this adapter provides a straightforward mechanical connection for ventilation and exhaust systems, enabling compatible diameter change in air-handling installations and domestic or light commercial HVAC applications.

## Long description

SpiroFlex adapter 80/110–80/125 TWK in white is a duct transition fitting designed to connect round ventilation ducts of differing flange profiles and effective diameters. The fitting provides a mechanical interface between an 80/110 mm round duct and an 80/125 mm round duct, allowing a reliable change in duct geometry for residential and light commercial HVAC and exhaust systems. The white finish supports unobtrusive installation in visible interior areas.
Advantages
The adapter offers a simple, tool-friendly connection method that secures compatible round ducts without the need for custom fabrication. Its precise dimensions ensure a tight fit to reduce air leakage at the transition point, and the lightweight construction makes handling and positioning during installation straightforward. The white surface is suitable for painting or integration with existing ductwork aesthetics.
Suitable for
Connecting 80/110 mm round ducts to 80/125 mm round ducts in ventilation and exhaust systems
Residential HVAC installations where a change of duct profile is required
Light commercial ductwork and small mechanical rooms
Retrofit projects that require adaption between different duct sizes
Key specifications
Transition type: round-to-round duct adapter
Input diameter: compatible with 80/110 mm round duct profile
Output diameter: compatible with 80/125 mm round duct profile
Material: lightweight engineered polymer with smooth exterior finish
Color: white
Connection method: mechanical slip-fit for compatible duct ends
How to use
Inspect both duct ends to confirm compatibility with the adapter profiles and ensure surfaces are clean and free of sharp edges or debris. Slide the adapter onto the first duct end until seated, then align the second duct and insert it onto the opposite end. Secure both connections following the ventilation system's standard practice, using clamps, tape, or sealant as required to achieve an airtight joint. Check alignment and airflow direction before completing the installation.
Usage recommendations
For optimal performance, verify that the adapter is used between compatible round duct profiles and that joints are sealed to prevent air leakage. Avoid using the adapter in high-temperature or chemically aggressive environments unless the material specifications are confirmed suitable. Regular inspection after installation is advised to ensure continued tightness and integrity of the connection.
