I need a co2 manifold for 5 taps. I'd prefer to make one as I am a plumber and can make one very easily out of copper and brass fittings with things I have on hand but all the ones I see are stainless. I would make it out of 1/2" copper tees with adapters to accommodate a ball valve and a flare fitting.
Is there a reason I haven't seen a copper one?
