We recommend using an inflator that has an auto shut-off feature to inflate foil balloons. The Snap-On Auto-Fill Foil Outlet, cuts off the flow of helium once the foil balloon reaches its desired size. This feature saves helium and balloon costs, as it is less likely balloons will pop. The Auto-Fill Foil Outlet, snaps onto Conwin’s 10ft Extension Hose Inflators with the Quick Disconnect Outlet. This will inflate all sizes and shapes of foil balloons (except Orbz balloons). To use this outlet, place the neck of the foil balloon over the filling outlet and press downwards. 


Warnings: You cannot fill latex balloons with this nozzle.
