ABSTRACT:
A screw-threaded connection incorporates dual synchronized threads, that is, one connection element has a set of external male threads that mates with a corresponding set of internal female threads on the mating connection element, in customary fashion. The first connection element additionally includes a second set of internal female threads synchronized with the first set such that the leads of both sets of threads are the same. This second set of internal female threads mates with a corresponding set of external male threads on the mating connection element. Of course, the two sets of threads on the mating connection element are synchronized such that their leads are the same, and, of course, the same as first sets of mating dual synchronized threads. This dual synchronized thread connection has application to any fluid connector and particularly to fluid connectors in wide-variant temperature deviation, high-pressure, and/or mechanical vibration environments.
