I wish I had taken a picture of this yesterday. At least in my area electrolysis will happen. They had used a galvanized union to connect two schedule 80 nipples that where too short. The union was corroded big time. So I have to disagree with your above statement. Salt air may not be an issue with you, but in our area it is. No harm done.
