Steve- I have the "3/8" UNF male tube nut" into the "1/8" NPT to 3/8" UNF Female adaptor" into the residual pressure valve which is 1/8" NPT and I will put a little sealer a few threads in, but you say sealer is not necessary? All four of my adapter to rpv connections leak. I think I got it a couple posts ago because it seems to be exactly what I have, but I appreciate everyone taking me through this.

Oh well - just make sure you give us an update with the 'fix'. These 'nigglers' are fun to talk through and most of us really like to spend other folks money as well.
