Abstract
A block fitting and seal structure for an air conditioning system includes a male block fitting and a female block fitting. The male block fitting includes an axially extending protuberant portion. A distal end of the protuberant portion has a tapered portion formed thereon. A female block fitting includes a recessed portion with a tapered portion formed therein. The tapered portion of the female block fitting is configured to engage the tapered portion of the male block fitting. An annular seal is disposed between the male block fitting and the female block fitting. The seal provides an axial seal and a radial seal between the male block fitting and the female block fitting.
