Long past the time of you caring, the joint will fail if you do not install di-electrics.
These should be used whenever you join a hard steel to copper. Broanze to copper, no problem. Any steel to copper, galvanic corrision sets in.
People get confused about heating systems and the standard use of black iron pipe which you would never use for water lines. People also get confused about di-electrics and the real reason for using them.
