That is the general consensus here, but I respectfully disagree. You may get away with it in this instance because of the low pressure but as a rule of thumb when pipe fitting it is a cardinal sin putting any kind of pipe together dry, regardless of the material. As you stated Brass is soft so it does seal itself easier than carbon steel or stainless, but it still can gall. The whole purpose of pipe dope is not to dry and make a seal but a lubrication for the threads to allow proper sink without galling or stripping the threads. I'm sure you know that, just putting it out for some that may not.

I personally dont use any dope or tape on my brass to brass or brass to iron connections and they have always sealed just fine. just my .

yeah that is a compression fitting adapter, put some teflon on the adapter that threads to the unit and you should be good. this is what i would do.
