With respect, I disagree with Bill on the pipe dope, which is a bitch to
clean off completely when you need to (and can wander into the plumbing just
as easily if done wrong).
Secret to Teflon tape, do not wrap the tape at the very last thread of the
fitting (same for pipe dope if you prefer that). But upon disassembly, the
tape is so much easier and cleaner to remove. I've also found if I need a
fitting to point to 12 o'clock, but it points somewhere else when tight, an
additional wrap of tape can adjust that easily.
BTW, proper AN fittings never need tape/dope. The angled seats do the
sealing (I crank mine pretty tight, BTW. Also I have the aluminum wrenches,
and to my non-engineer "feel" the handles seem to be made to just the right
length/leverage to provide the correct fit from hand-tightening). Pipe
threads always need the tape/dope.
The only leak issues I've experienced have always been with pipe thread
fittings. Even with tape/dope. (Issues, that is, not directly attributable
to it being a British car! :-)
