: Yes there are. Go to your local Home depot or similar store and go to the pipe/valve section. tell the employee what your looking for. Do not attach the galvanized to the copper pipe w/o using a special adapter (i forgot the name.) It has a plastic sleeve so the two different metals dont touch. If they touch and the copper water line is used as a ground, there could be a problem. IT IS CALLED A DIELECTRIC UNION it prevents electrolis between two dissimilar metals.
