Good quality AN fittings have a standoff spec. and there is a gauge that you use that fits between the stationary and threaded ferrule nut. I have a set of those gauges that are like brand new because they have never left the case.The actual torque for fittings is FAR FAR lower than almost everyone thinks.
Over-torquing causes galling and splits banjo fittings, mushrooms and cracks flare types and generally fucks things up.
Everyone over tightens fuel, oil and brake fittings.....it's an insecurity thing because they don't actually know the spec.
I like the liquid sealant myself, it cleans up better and does a better job sealing NPT.
Like anything, almost EVERYTHING has a spec, lubed, dry, type of lube etc....RTFM or keep on guessing....
