## Long description

SpiroFlex 60/100–80/125 adapter T (model SX-TD-AT) is a ventilation duct transition fitting designed to join and branch circular ducts with combined diameters 60/100 mm to 80/125 mm. The T-shaped adapter provides a clean and compact solution to convert duct sizes or create a branch in ventilation and HVAC runs. It is intended for use in residential and commercial installations where reliable airflow distribution and straightforward mechanical connection are required.
Advantages
The adapter offers a straightforward mechanical connection between differing circular duct sizes, reducing the need for on-site custom fabrication. Its T configuration enables both size conversion and branching in a single component, saving installation time and simplifying layout. The fitting is compatible with typical spiral and round duct systems and supports secure sealing for efficient airflow management.
Suitable for
 Branching ventilation runs in residential systems

Key specifications
 Configuration: T-shaped adapter for duct transition and branching
 Compatible duct diameters: connection between 60/100 mm and 80/125 mm circular ducts
 Application: ventilation and HVAC air distribution
 Mounting: inline mechanical connection to round/spiral ducts
 Function: size conversion and airflow branching
How to use
Position the SpiroFlex adapter T where the duct run requires a branch or diameter change. Align each circular duct end with the corresponding adapter outlet and secure using appropriate clamps, rivets, or metal screws according to the duct system in use. Ensure mating surfaces are seated fully and apply compatible sealing tape or gasket material at joints to minimise air leakage. Verify that the adapter orientation provides the intended airflow path before final fastening.
Usage recommendations
For optimal performance, use the adapter with matching spiral or round ducts and follow standard HVAC installation practices. Check compatibility of fastening and sealing materials with the ductwork and local building codes. When used in systems with significant pressure or noise concerns, consider additional sealing or insulation around the adapter and validate airflow balance after installation.
