thank you that is so helpful!
This article suggests yellow tape is the preferred sealing method and adequate:

Inverted flare......
Did you open the Link I posted to types of fittings?
Scroll down and look/read about #3
Did you crack the regulator by overtightening??
Is it time for your medication or mine?

This forum has a separate photo posting site. You upload it there and it gives you a link to post in your reply.
Yes you can overtighten most nuts and that's not good. A threaded connection is more forgiving to accidentally over tightening. As you tighten the nut or bolt, the threads begin to stretch.
A flare connection is 2 similar shapes getting pressed together. Once its snug it only takes a little bit more for it to be tight and not leak.

yes i did look at the link and yes I think I have #3, BUT it seems like the little brass ?adapter that goes on the regulator is now 1. on the old pigtails I removed and 2. integrated in a single piece with the new pigtails I bought.
I don’t believe the regulator is cracked. how would I know? One of the pigtail’s rubber is cracked, so I decided to replace both. I doubt that’s where it’s leaking, but I really don’t know. It just seems like I’ve stuggled with this even with the prior (original, from 2017) pigtails that cracked after 18 months, again I don’t think the cracking is where the leak is, but it’s a sign of aging and maybe a poor quality product, and it seems the propane tends to leak out even when there is no drain on it. The water bottle test doesn’t reveal any obvious leaks/bubbles.

However, the new replacement pigtails seem to have an integrated brass piece so that it would attach directly to the regulator, with no additional adapter needed.
This is what I bought

I can see how that would work, but the NPT end I have seems to be exactly what I removed from the regulator, and is currently attached to my old pigtail. Translation: why can’t I use the ones I bought and attach directly to regulator using yellow tape? Will that not work?

There is nothing wrong with using the NPT pigtails. A little more caution on putting on sealant whether it be Teflon tape or a good quality paste type.
Care must be taken as to not over tighten and stripping threads out of the regulator.

actualy it doesnt, it says it is more conventiant for the worker to use as it is easier to carry , doesnt have a shelf life, and has no cure time. if you dont wrap it properly it can be the worst one you'll use.
I used to work for a gas company when I was a young lad and we would have been fired for using tape instead of liquid sealers. if you notice when the rv's come from the factory they use a liquid sealant also. the choice of liquid sealants is just as important though, you want to get a non hardining one, so it sets up but doesnt harden like a rock.
