I've just picked up a new portable compressor, hose and an array of fittings
~ all connections will be brass to brass. Do I need plumber's tape for these
fittings or should I be fine with just the brass to brass? I was wondering
what others have done?
I've successfully used teflon tape on a gazillion brass, plated-brass and
steel compressed gas fittings, from a couple of hundred psi all the way up
to several thousand. It can cause problems when it is improperly applied,
e.g. bits of it are carried into the system. But anything can cause
problems when it is improperly applied. I wouldn't hesitate to use teflon
tape on compressor fittings.
You NEVER want to use Teflon tape on combustion plumbing.
Sooner or later, bits of the tape will break free and end up plugging
the combustion orifices.
A principle of mine was paid in excess of $10,000 for a service call
to a refinery for a piece of combustion equipment they had sold that
the refinery installed.
Emergency travel, weekend service rates, car rentals, etc, etc, all to
discover a plugged orifice from Teflon tape.
It was rookie mistake by a refinery worker.
Less than 15 minutes to solve the problem, but still had a $10,000
invoice to pay.

I certainly can't fault your advice other than to mention that
combustion plumbing is a little outside the scope of the OP's
question. Which, if I read correctly, involves plumbing for compressed
A mater of standardization.
If you are going to need Teflon paste for some possible applications,
why not use it for all?
Can't be cost, a bottle of Teflon paste is only a couple of bucks.
And unless you are a pipe fitter or a plumber, a small bottle is
probably a multi year supply.
TFE can become tiny parts. It will clog gas gets and
kill those inside.
Thus the hot water heater if gas - use plumbing gunk to lock it up.
Plasma torches and the like have small holes - as do paint guns
and the like.

Well, you need *some* kind of pipe dope in there, if you think you'll ever
want to take the joint apart a few years down the road. Some folks will tell
you never to use teflon tape with compressed air, but I've never had a
problem. Just make sure you apply the tape to the male threads only, and keep
it on the threads -- don't get any into the air passages.
