Nickle is part of the chrome process and all valves are brass or aliuminium as far as I know.I don't think I have ever seen a valve rust before.Ive seen steel fittings rust and fuck some shit up though.Your best bet is to buy fittings with a dot stamp on the head that way someone is regulating the quality.On the lines most people use stainless and polish it when there done.You have to have a special bender because it's hard as hell.Ive seen people chrome copper line but thats not very cost affective or half as strong.
