DuraVent B-Vent Universal Adapters

Use the male adapter when converting another manufacturer's B-vent to the DuraVent B-Vent when the DuraVent will be on the top side of the vent pipe. Use the female adapter when converting the DuraVent type B-Vent to another manufacturer's type B-Vent when the DuraVent will be on the bottom side of the vent pipe.
