Abstract

A connection joint brazed to a heat exchanger may employ a first block and a second block. The first block may have two fluid passages that align with two fluid passages of the second block. A first male insert may reside within a first fluid passage of each of the first block and the second block and a second male insert may reside within a second fluid passage of each block. Each of the male inserts may employ a first seal and a second seal with a raised boss region midway between the seals. The raised boss portion lies at the mated flats of the juncture of the first and second blocks, which are chamfered to permit part of the boss to locate in each of the chamfers. The seals may be o-rings, or they may be molded onto an insert base using an over molding or double shot manufacturing process.
