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.
