Abstract
A fluid tank assembly comprises a first tank half having an upper edge flange with an expanded section or ledge extending outwards. A second mating tank half similarly has a lower edge flange and extending ledge. Both ledges have apertures, with lower ledge aperture having a smaller diameter than the upper ledge aperture. The second aperture has a raised edge or lip, so that an annular groove is formed between the lip and the inner edge of the upper aperture when the surfaces of the mating flanges and ledges are in contact and the apertures are coaxial. The two flange and ledge surfaces are normally welded or otherwise secured together. A binding material is added to the annular groove to substantially fill its volume so that a sealing connection is created. This sealing connection near the bolt aperture overcomes the sealing problem that is normally present in this region, and therefore extends the service life of the tank.
