Abstract
An air duct system for transferring air or the like from one component to another includes a tubular body with an exterior surface, an interior surface, and an end which connects the exterior surface to the interior surface. The end has a diameter no larger than the exterior surface. The internal cuff connects to the exterior surface and extends axially from the end of the tubular body. The external cuff connects to the internal cuff and the exterior surface, and extends axially and radially from the internal cuff and the exterior surface. The external cuff is made from a material relatively harder than a material used for the internal cuff.
