Strictly speaking, Nick is correct. No sealant is needed on a the faces of a ground union. My theory is that a light coating of a light teflon based joint compound acts as a lubricant and anti=corrosive agent.

This is just my personal practice, and
I look forward to hearing the opinion of more experienced professionals.
