This Aerospace Information Report (AIR) indicates those dimensions, deemed critical by the manufacturer to assure proper mating of disconnect hose fittings. The dimensions are critical, but not necessarily complete, in defining these fittings since there are other criteria which must also be met.

This AIR defines by drawing, various available oxygen hose disconnect fittings. The intent is to provide enough data to examine a connector of uncertain history and determine what style of connector it is. This AIR does not offer sufficient information to design, manufacture, or qualify a confirming part.
