If you are referring to teflon tape, avoid it like the plague.

You want teflon paste.

Yes, you want to seal the thread connections.

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.
