An air duct connector is used to create an air-tight connection for duct work. A method of using the air duct connector includes cutting a strip of an air duct connection gasket along a first start edge. The strip is adhesively attached around a metal connector band such that the air duct connection gasket fully encircles the metal connector band and an adhesive attachment is formed with an adhesive backing. The strip is cut along a second close edge which matches the first start edge and the strip is positioned such that the first start edge mates together with the second close edge at a sealing seam. The air duct connection gasket includes a first sheet section extending generally in a planar sheet between a first side edge and a first central edge. The first sheet section has a first sheet width which is substantially wider than a first sheet thickness. A first sealing rib extends longitudinally on a front face of the first sheet section and defines a flexible fin. The air duct connection gasket also includes a second sheet section extending generally in a planar sheet between a second side edge and a second central edge. The second sheet section has a second sheet width which is substantially wider than a second sheet thickness. A second sealing rib extends longitudinally on a front face of the second sheet section and defines a flexible fin. A bead extends longitudinally between the first and second sheet sections along the central edges. The bead has a thickness which is substantially thicker than the first sheet thickness and the second sheet thickness, and the bead has a width which is substantially narrower than the first sheet width and the second sheet width. The adhesive backing is located on a back face of the first and second sheet sections opposite the front faces.
