Abstract: An improved fitting for mobile air conditioning systems is disclosed that reduces the risk of damage to fitting O-rings during assembly, the fitting male member being compatible with the fitting female member of many existing fittings currently in service. In particular, the male fitting (152) is compatible with female fitting (72) that comply with the IMACA 305 Standard. The male fitting includes a circumferential bead (158) that engages the distal end of the female member, an intermediate tubular portion (155) that extends distally from the bead, a tubular pilot portion (156) that extends distally from the intermediate portion, and a retainer bead (157) disposed between the intermediate and pilot portions. The retainer bead is positioned to retain the O-ring (51) near the circumferential bead, without interfering with proper compression of the O-ring, and full insertion of the male member into the female member.
