A low profile secondary seal has a tube positioned above a primary seal that utilizes a shoe plate. The tube is connected to the floating roof. A tip seal adjacent the shell of the tank is connected to the shoe plate by a spacer. In use, the tube bears on the spacer with sufficient force to maintain the tip seal in sealing engagement against the shell of the tank.
