Abstract
A circular sheet metal duct having a sealant applied across the longitudinal seam. The sealant will improve the efficiency and will reduce or eliminate air leakage from the longitudinal seam. The sealant is applied during the manufacturing processes so that an installer does not have to seal the duct work. The method of manufacturing the sealant is provided.
