Can galvanized fittings be used in an oxygen supply line? The gauges on my oxygen tank are too low for me to read and I want to arrange them so they face up rather than forward. Brass fittings cost 3 to 4 times more than galvanized.

as you have been told and i agree. use only brass.
the reason is safty. any spart generated by anythink like steel could cause harm,to you.
yes they cost more,or do you what to be hurt or injured or worse?
do what is safe.
Be sure you get fittings rated at the proper pressure if you're also modifying the high pressure gauge.
I don't know what the specs are for oxygen service, but I imagine the brass is used for corrosion resistance. I don't know how well the galvanized will hold up. It may quickly corrode all the zinc, and then start attacking the steel.
