Anyway, if one is using a compression fitting, pipe dope or tape is not
needed, and may in fact be detrimental to the connection. I have seen
compression fittings where pipe dope was used on the joint by someone
who didn't know any better.

As long as you keep it on the threads, and off the ring, where's the harm?

Or gain? If a compression fitting leaks, sealant on the threads won't
do a thing to help contain the leak.
