Theres always someone who will tell you horror stories about using brass on copper, but for the amount of usage the typical 3 1/2 boiler gets it wont make a jot. If your using it for stay or boss remember it expands like billyo when heated and always ends up oversize! Bronze is better, but megger expensive!
