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?

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.

Verbatim quote with no further info. However "brass" is a
pretty elastic term.

From "Casting Brass" CW Ammen :-

Yellow Brasses 63 to 72% Cu
Red brasses 83 to 85% Cu
Aluminium bronze 81 to 89% Cu

Unspecified brass is probably OK - but are you feeling lucky?
