both ends are 9/16-18 threads on this thing, right? just want to make sure before i order a handful of em

Correct on both counts. The male JIC end and the female swivel end are both 9/16-18, so you've got matching thread size all the way through. Both connections conform to SAE J514 and use the 37 degree flare angle, which is standard JIC. Should drop right into a system already running that thread spec without any adapter shuffling.
