The female knurled nut that goes to the outlet of the N2 regulator had a burr that initially prevented it from tightening fully into the 1/4" flare. I managed to clean up this thread a bit with a hook needle and seal it with a small movement of the pliers. I don't plan on removing it from the regulator and it seals, so it's fine. One star off for tight threads.
