Galvanized pipe and fittings are for water, not gas.

Or more specifically for OP if indeed didn't know, galvanized is not used
for gas because impurities in natural gas can react negatively w/ the
zinc.


That's an old wives(husbands) tale.This used to be the case years ago when
the zinc coating would flake off, but methods of bonding have improved
over the years. Galvanized sched. 40 pipe is not only approved but is
recommended for natural gas use, specially outdoors and/or underground,in
most juridictions.

6. Galvanized coated pipe is not deemed adequate coating for underground
use.

Galvanized pipe is commonly used for water systems, black pipe for
manufactured and natural gas. Galvanized pipe should never be used for gas
installations. Plumbing codes in many areas require that black pipe,
especially that used underground, be coated and wrapped.

Our local inspect still does not allow galvanized for any gas. That varies
by jurisdiction.
