Should teflon tape or putty be used when connecting brass air hose fittings together?

Should teflon tape or some type of putty be used when connecting brass air hose fittings together to prevent air leaking?

The "should" is up to you.

I'm partial to the sealant putty as it has, I think, less potential to be blown downstream inside the air line to, perhaps, interfere with the operation of a downstream air component.

If you exercise care when using the tape however, it's good to go too. It's just that I've seen what happens to a valve when a piece of tape, carelessly applied to a fitting and overlapping the I.D. of the fitting, gets blown down to the valve, and cause it to stick.

A personal choice, Steve. Whatever you use, use it properly, and you shouldn't have any problem.

Cheers,
