Did you put a little oil on the o-ring/gasket before you tightened it down?
I didn't use thread sealant on the AN fittings, but I used a compound (I hate the tape) in all the bspt and npt fittings. It worked so well that it sealed a bspt->npt junction with no leaks (they're similar at that size but not exact). If you go that route make sure to get one rated to the temperature and pressure that you'll expect to see
