Beschreibung
Zusammenfassung:	A fitting assembly for connection to a flexible duct includes a fitting and a ferrule extending from the fitting. The ferrule includes a first end configured for insertion into an open end of the flexible duct, a second end adjacent to the fitting, and a sidewall extending between the first end and the second end. The sidewall defines a minor diameter adjacent the first end and a major diameter spaced apart from the minor diameter. The ferrule further includes a ferrule thread extending radially outward from the sidewall. The minor diameter is less than or equal to an inner diameter of the flexible duct with the flexible duct fully elongated, and the major diameter is greater than the inner diameter of the flexible duct with the flexible duct fully elongated.
