Re: thread sealant
I've been using TruBlu by Rectorseal available from RPW or whatever they are called now, FSW?
Used it on R22 R134a and R404A for fusible plug threads and compressor oil plugs. Not had one leak yet.
Not had much success with that stuff NRS/climate does, it seems to dry out after time and go all crispy, have had to work on txvs where previous enginner had used it, nightmare to get ride of to get a good seal again.

Re: thread sealant
Leak Lock is what I use on gas and refrigerant lines. It's the obnoxious blue stuff that doesn't come off.
