Outside my home I have a capped-off galvanized pipe stub-out. It connects 18 inches underground to PVC water pipe. I would like to attach a common garden hose bibb (sillcock, spigot). These are made of bronze. Is there risk of galvanic corrosion between the bronze fixture and the galvanized pipe? Should I install a dielectric union or use instead a stainless steel fixture? I have not seen this elsewhere. Other homes have these fixtures attached to galvanized steel. There is no frost in this area.

Bronze is not going to create galvanic corrosion when attached to galvanized pipe.
