I don't know what is proper.  Teflon on tapered threads lead to splitting things and sure doesn't stop anything from leaking. lock tite sometimes seems to work on some non tapered stuff; but, I personally like permatex super 300 aviation grade, now simply sold at auto counters everywhere as permatex #3.  It is black, gooey and never completely dries, stops almost anything from leaking and seems to hold everything together almost as good as duct tape on panels.

What is the appropriate method for ensuring a snug fit and preventing vibration or pressure induced flexing/loosening. Likewise, sealing options for other threaded ports (not the flared sides of the AN fittings, but the pipethreaded end of the fitting).

Teflon?  Lock-Tite? Whats the answer?
