You have several things in your favor. First, cast iron is not the same as steel. Second, it is a closed system so oxidation and corrosion is a minor consideration. Third, you are connecting to brass valves and return ells. For these reasons, and there are others, you do not need dielectric unions. : I'm installing some cast iron radiators in a new addition we built, I'll be connecting the radiators to 3/4" copper tubing. How important would the use of dielectric nipples be in the connection? If not used, what can I expect?
