When plumbing ASI, ALT, AHRS, etc. with Ny-Loc fittings, do we use anything
on the pipe threads? Teflon tape, EZ-turn lubricant, etc.?
TIA,

These are under very low pressure so I used just a little teflon tape
(probably could get away with nothing). Some quick release fittings that
came in a kit I bought had the tape already on them too.

I just did a pitot-static inspection on a new g100 cessna 172 yesterday and
there were leaks everywhere.... check the pipe thread segment of your
connections that go into the instrument for what i will call "crappy
manufacturing" These little suckers are molded and sometimes are left with
a flash line that runs down the thread. I took out all the instruments that
were easy to get at and put teflon tape on the fittings, finally getting the
leak rate down to about 80ft/min at 1000' above my field elevation. Good
enough!
I have also heard or using DC-4 silicone lubricant instead of the EZ-turn
honey like stuff that can just lead to a mess.
