BULLCRAP! soldered copper fittings in an air system would only fail if
you are LESS than a MORON! Where do you come up with this alarmist BS,
anyway? If there was a leak at a fitting, you'd probably hear it
anyway. I'm no PRO at sweating fittings, but I did an entire shop with
copper that lasted 8 years and all my friends in the business used the
same methods to build their air systems. Don't pass Go, go directly to

Ok, I will throw my 2 cents worth in on what may be a bit off topic to
you. I would not use copper. If you use a length of common high pressure
air hose to connect your current tank to the air line it should dampen any
air pressure surges and pump vibration besides eliminating the problems of
hooking a solid line to a solid tank. But if you spray contact cement or
some finishes the moisture in the air will react with the copper in the
lines and cause contact cement in particular to chrystalize and fail. This
is not an old wives tale and is a known issue for shops that do upholstery
and plastic laminate work. However, if the air line is just used to
service common air tools for machine work or automotive work it will work
fine, though the thicker wall copper is recommended, along with drops and
drains at low points in the line.
