Abstract
A method for manufacturing an air duct includes providing a tubular body having at least one open end which is inserted into an internal cuff mold to form an internal cuff that is secured to and axially extends from the tubular body. The tubular body and the internal cuff are removed from the internal cuff mold and then inserted into an external cuff mold to form an external cuff that is secured to and radially extends from at least the internal cuff. The tubular body with the internal cuff and the external cuff is then removed from the external cuff mold.
