Couplings and fittings
Every fitting is made from heavier-weight fabric to withstand turbulence where the airflow changes direction, and sized to the diameters of your system.
Joining duct sections
Coupling types
Three ways to join duct sections. Not sure which one suits your line? We will advise you when you request a quote.
Snap coupling
Joins sections with quick-release snap hooks.
Steel ring coupling
Joins sections with a steel ring built into the duct end.
Direction changes and transitions
Fitting types
Made from heavier-weight fabric to withstand turbulence where the airflow changes direction.
Tee fitting
90° branch to two headings.
Wye fitting
Symmetrical, low-loss split.
Lateral branch
45° branch off the main line.
Fan adapter
With strap and ratchet.
Reducer
Transition from a larger to a smaller diameter.
Round-to-oval adapter
Connects a round line to an oval line.
