A quick connect diagnostic system is disclosed for detecting the pressure and temperature of fluid streams flowing in fluid flow passages in engines or the like. A plurality of female portions of the quick connect mechanisms, which include foot valves, are permanently connected to different fluid flow passages in the engine. During normal operation of the engine dust caps are locked in the female portions and include at least one O-ring seal to cooperate with the foot valve to assist in preventing leakage. When testing for temperature or pressure of the fluids, temperature probes or pressure probes with transducers thereon, are inserted into the associated female portions causing O-ring seals to seal the quick connect coupling prior to contacting and opening the foot valves which subject the pressure probes to the fluid pressure in the associated passages, and which project the ends of the temperature probes into the flow streams being tested. The transducers are connected to a test meter which provides accurate readouts for the pressures and temperature in the several passages being tested. Several embodiments of quick connect coupling are disclosed for use alone as a sub-combination, or for use in the system.

A quick connect diagnostic system comprising: means defining a fluid flow passage with a fluid stream flowing therethrough; means defining a first portion of a quick connect mechanism having a normally closed valve therein secured to said flow passage means in communication with the fluid stream and movable between said closed position and an open position permitting fluid to flow therepast; means defining a second portion of the quick connect mechanism which includes a probe for opening said foot valve when coupled with said first portion, said first and second portions including at least one seal member therein which seals the first and second portions together prior to opening said foot valve; means defining a quick connect latch for releasably latching said first and second portions together when coupled together; a transducer connected to said probe detecting a signal indicative of a characteristic of said fluid in said flow passage; and meter means coupled to said transducer for providing a reading indicative of the fluid characteristics being tested, said probe being a temperature probe which enters the stream of fluid in said fluid flow passage for determining the temperature of the fluid.
