Abstract
Abstract A screw-threaded connection incorporates multiple synchronized threads, that is, one connection element has one or more sets of male threads that mates with one or more corresponding sets of female threads on the mating connection element, in customary fashion. Of course, the multiple sets of threads on the mating connection element are synchronized such that their leads are the same, and, of course, the same as the sets of mating multiple synchronized threads. This multiple 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.
