    Question Fittings on Oxygen Supply Line

    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.

    Twist the regulator and position it easier to see before you tighten it.

    All fittings used in fuel gas and oxygen lines should be of a non-sparking material...

    Follow this advice. Three to four times the cost in this instance is only a couple dollars. Brass is also a soft material so it seals better & less chance of ruining the regulator body.

    Default brass

    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.

    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.
