that's odd. Victor lists their regulator as "All brass acetylene regulator
(CGA200)" and brass is 70% copper and 30% zinc. The fittings I used were
brass, same as the regulator. What material do they recommend as
acceptable?

I can't say with unequivocal certainty, but most heavily machined fittings
are free-machining yellow brass, 37% Zn, 3% Pb, ~59% Cu, which would fit
with the requirement below.

BOC (British Oxygen) specify that joints or fittings in contact
with acetylene must not be of copper or any alloy containing more than
70% copper.
