Its a given. *Its pretty much Verbotten to use galvanized pipe with

A good point and another reason to use a filter/regulator/oiler
immediately before your air tool or other equipment and no teflon
tape, etc. on the downstream side.

For an example see:http://www.use-enco.com/CGI/INPDFF?P...Item.do?itemid...
and many others.

"no teflon tape, etc. on the downstream side. "

There's nothing wrong with properly applied teflon tape. It's
when it's applied to the last and next-to-last thread on a
fitting that it becomes a problem. Before I began work-
in in the service department I applied tape to thousands
of fittiings without problem. Others, less attentive to details,
had numerous problems. We were all using the same tape
and fittings so I've concluded application is the key.
