A method and apparatus for readily connecting a main component of a forced air heating and/or cooling system to a branch component so that the connection is airtight. An elongated tubular member has an enlarged circumferential face generally perpendicular to the direction of elongation of the tubular member formed at one end of the member, with a gasket attached to that face, glue on the exterior of the gasket, and a piece of release paper over the glue. The passageway through the tubular member is matched up with an opening in the heating system main component so that the gasket surrounds the opening in the main component, and the gasket is then pushed into the sealing relationship with the main component, the glue on the gasket face joining the tubular member and main component together. Then fasteners are passed through openings formed in the tubular member and gaskets so that the fastening members operatively engage both the tubular member and the main component and securely hold them together. The branch component is then placed around a second end of the tubular member and sealed into contact with it. When the tubular member is of plastic, fiberglass, or the like, it is desirable to provide a metal collar between the fastening screws and the enlarged portion of the tubular member before passing the screws into operative association with the main component.

A method of connecting up a sheet metal main component and a branch component in a forced air heating and/or cooling system, utilizing a connecting component comprising an elongated tubular member having a passageway, and having a first end with an enlarged circumferential face generally perpendicular to the direction of elongation of the member, and a second end adapted to receive a branch component therearound, the first end face having an annular gasket of flexible material operatively affixed thereto, the gasket having an exterior face with glue thereon, and an annular section of release paper covering the glue, and the first end having plurality of openings extending therethrough, and through the gasket, generally parallel to the direction of elongation of the tubular member, said method comprising the steps of (a) providing a generally circular opening in the sheet metal main component having substantially the same cross-sectional area and shape as the section of passageway in the elongated tubular member surrounded by the tubular member enlarged circumferential face; (b) removing the release paper from the tubular member gasket; (c) moving the tubular member into operative contact with the main component so that the gasket surrounds the opening in the main component and tubular member and main component together; (d) passing sheet metal fasteners through the openings formed in the tubular member first end so that the fasteners operatively engage both the tubular member and the main component and securely hold them together; and (e) bringing the branch component into operative airtight relationship with the tubular member second end, so that an airtight passageway from the main component to the branch component is provided.
