How is it I don't know this stuff？Swivel nut Setting and Adjustment on Regulator.

I am not sure what you are asking. Is it leaking? I have a similar looking mini-regulator. That is just a connection from the regulator to the disconnect. When the connection is not fully tightened, you should be able to twist the regulator side so that the gauge and cartridge are pointing in reasonable directions. I don't think you need teflon tape on any of these connections.

I understand it to be a swivel thingy that as you said, lets me rotate things so they can be lined up as wished. When everything is tightened, nothing freely rotates.Of course, if I unscrew something then yes, something moves, but not in the sense of a swivel, more in the sense of simply loose. There is a condition I don't know how to create, where the swivel allows me to rotate freely but only in one direction. (going the other way just makes it unscrew)
So my only choices are Fixed position or too loose... And occasionally for some reason, free rotation but only in one direction.

Could you unscrew the four parts and lay them out for a picture so we can see the mating ends?
That would help us answer more accurately.

And I concur, tape should not be needed for the 1/4" flare on the QD. The other joints are subject to inspection to confirm what joint-type they are.

It had teflon tape on it when I got it...I was always unsure about if it was supposed to... today I was going to replace it, but noticed difficulty and new behaviour. Hard to pinpoint, but increased freedom of movement plus a tendency to loosen sooner than before.
Anyway, no teflon now.

The answer: "The gobs of tape used indicates the parts don't actually fit together in a legit fashion".

Ha ha... could be but I hope not. I haven't been able to attach it again WITH tape attached so not sure whats what. Are you using one like this? The brass thing on the right requires a hex key (forgot the real name) to un-screw. BTW... Which nut (?) is supposed to be the swivel-er? the knurled brass step down adapter lin the middle or the one on the right that requires the hex key?
Should it provide unlimited rotation or only unidirectional rotation？

And that is exactly how I found all our expensive 1" hose x 3/4" hose reducers at work - threaded onto 1" pipes.
It swivels to assemble it. It's not meant to swivel when it's tightened. No, you do not use teflon tape on flare connections. Remove that.

Are you sure about that? I thought the swivel was to allow different usage orientations once it was set up....
BTW when thinking about what pictures to take, I observed the following: There is no Swivel when the middle Knurled Brass is well tightened to the gray post: everything is locked down. If I loosen the grip between them, the smooth brass rotates freely for as long as I care to spin it; I think that is the swivel and it operates by use of an Allen Wrench inserted into the threaded screw foot-part presumably enlarging part of the threaded foot while letting the cup spin, and, alternately, turning the allen the other way, loosens the the smooth brass swivel unit (for removal from the regulator) ; Pictures? I think "moving pictures" are necessary here!

Correct.
What is that brass bit in the middle? I have a mini reg that has a flare connection on it, no adaptor needed for a qd.
That is also how mine works. When the nut onto the disconnect is a little loose, you can twist the regulator side into position. When you tighten that down it seals the flare thread and also locks the regulator in place.

Honestly I could see maybe a single wrap of tape or some pipe dope on the threads to reduce friction and prevent corrosion but that’s it. It’s not a pipe thread that jams to make a seal it’s the flare faces mating that make the seal
Ok, unless the reach of the QD stem isn't long enough for its tip to seat against that rubber gasket, there's no need for tape on that connection. And the same deal applies to the male threads on that brass adapter: if the tip can reach the white plastic gasket inside the regulator receiver, there's no need for tape on that connection, either...

Yeah I'm sure. All the swivel barb to ffl fittings on keg lines are the same. The nut swivels so the hose doesn't get twisted on assembly. On this mini reg you can adapt it to various positions until the gasket gets tight.
Is the piece that screws onto the QD actually a swivel / two-piece adapter or is it one solid piece?
If two-piece true swivel then tightness and alignment as one desires should present no problem. If one piece then it will be trickier, although certainly not impossible, to get everything tight and in the desired alignment.

It definitely swivels. The 1/8" BSP threads are part of a flare "tailpiece". You can see that it's not machined from a single piece by this gap here..
