Apparatus for directing a flow of pressurized air into a vehicle or other compartment includes an air inlet fitting mountable in an opening in the compartment and an air bag connected to the air inlet fitting. When mounted in the compartment opening, the fitting forms at least one smaller opening between its own perimeter and the perimeter of the compartment opening. The air bag is inflatable in response to the flow of pressurized air. It includes an inlet opening for receiving the flow via the fitting and an outlet opening for exhausting the flow inside the compartment. Further, the air bag is sized to permit a first portion of the bag, including the outlet opening, to remain inside the compartment while a second portion is withdrawn from the compartment through the smaller opening. Upon inflation, the bag then expands on opposite sides of the smaller opening against the compartment and the fitting with air sealing pressure along the perimeter of the smaller opening
