## Summary description

SpiroFlex SX-TD-AJ adapter for duct transition between diameters 80/110 and 80/125. Designed to connect compatible circular HVAC ducts and components, it provides a mechanical transition for ventilation systems. Suitable for installation in residential and light-commercial ventilation, it ensures correct fit between mismatched duct sizes and facilitates airflow routing.

## Long description

The SpiroFlex adapter SpiroFlex 80/110-80/125 for duct transition, model SX-TD-AJ, is a mechanical connector designed to join circular HVAC ducts and components with differing diameters. It provides a secure transition between an 80/110 mm combination connection and an 80/125 mm combination connection, enabling proper alignment and airflow continuity in residential and light-commercial ventilation systems. The adapter is intended for use where duct sections, fittings or devices with slightly different collars must be linked without modifying the ductwork.
Advantages
This SpiroFlex transition adapter offers a precise fit for mismatched circular duct sizes, reducing the need for custom fabrication. Its design simplifies installation by providing consistent mating surfaces for compatible duct collars, helping to maintain airtight connections and steady airflow. The adapter supports installation flexibility in confined or retrofit situations and helps preserve system performance by avoiding abrupt changes in flow path geometry.
Suitable for
 Connecting circular HVAC ducts with 80/110 mm to 80/125 mm collar dimensions
 Residential ventilation systems and light-commercial ductwork
 Retrofitting or modifying existing ventilation routes without cutting or rebuilding ducts
 Linking ventilation components such as silencers, dampers, or fittings with different collar sizes
Key specifications
 Transition type: circular duct adapter for differing collar diameters
 Input collar compatibility: 80/110 mm configuration
 Output collar compatibility: 80/125 mm configuration
 Application: mechanical transition for ventilation airflows in residential and light-commercial settings
 Installation method: slip-fit mating with appropriate clamps or fixings (fasteners not included)
How to use
Position the adapter so that each collar seats properly onto the corresponding duct or component collar. Ensure mating surfaces are clean and free of debris. Slide the adapter onto the smaller and larger collars until fully engaged, then secure the joints with suitable clamps, tape or mechanical fasteners according to local practice and codes. Verify alignment and seal to prevent leakage and confirm unobstructed airflow through the transition before completing the installation.
Usage recommendations
Use corrosion-resistant clamps or approved sealing materials to maintain airtight connections. Inspect the adapter and surrounding ductwork after initial operation and periodically during maintenance cycles to ensure seals remain intact and that there are no signs of mechanical stress or airflow restriction.
