A drain fitting includes a cylindrical body that is sealed against a floor drain cover to confine condensate liquid, such as from an air conditioner, inside the perimeter of the drain fitting by tightening a self-tapping screw that is inserted into a hollow stem in the center of the central body portion of the drain fitting, pulling a gasket in the bottom surface of the drain fitting against a floor drain cover. A nipple connected to the drain fitting receives a condensate drain hose. A vent opening is formed into a side wall of drain fitting.
