Section 5.27 tells us about using Permatex #2, Tite-seal, or Loctite 565 on pipe thread fittings...
I've been applying Permatex #2 to AN threads.. does it also get applied to the nipple/flange side of the fitting as well? (the side where a flanged tube mates to the fitting with an AN nut).
I don't think so? I don't see how it would prevent a leak on this side of the fitting.
"Because we cannot always fully tighten tapered thread fittings, and because even after fully tightening the fitting a small spiral leak path remains along the full length of threads, a thread sealant must be used during assembly"
