A bolt-on fitting is shown for coupling a fitting to an object having external sidewalls and a normally closed interior containing a liquid, such as a water heater tank or boiler. The bolt-on fitting has a body with an inner surface and an outer surface. A plurality of bolt openings are spaced about the periphery of the body. An O-ring is located on the inner surface for sealing between the flange and the mating surface on the tank. The inner surface of the flange is concave, being curved about both a horizontal and a vertical axis drawn to bisect the body so that the bolt openings form isolated points of contact with the tank surface when the flange is bolted into position.
