Abstract
A connecting member having an elongated passageway defined by a tubular wall extends from a first end to a second end, with the first end adapted to mate with a main air handling system. The tubular wall is provided with a bead adjacent to, but spaced from the first end, and an independent collar having a central opening dimensioned to correspond to the dimension in the bead is fitted about the outer periphery of the tubular wall in the bead. A gasket having an adhesive outer surface is fixed to the collar and facing toward the main air handling system, with the portion of the tubular member at the bead extending through and protecting the gasket from fire risk and deterioration from an air stream passing through the connecting member.
