I have cut many a freon tank apart and all only had a typical valve

partially filled freon container they had to put the old freon in, as
they had to repair a slight leak. A used propane tanak IMHO would be
a safer container to utilize for a portable air storage tank. They
even have a standoff ring on the base to keep it from getting dinged
and scuffed etc, and not those pressed out dimples. A propane tank is
meant for reuse, where a freon container for the most part is made to
last only so long as its disposable. Should easily be able to get an
old style propane cylinder, and the valves are not all that hard to
get out.


The deal here is that the older tanks with black plastic valves do
not have the check valves. The newer tanks with colored valves have
the seat of the valve not connected to the valve stem. Thus it falls
and acts as a check valve preventing filling of the tank.

I've used a freon tank as a air tank for years. It eventually
started leaking at the blow out disc of the tank. But after cutting
them apart and seeing how thin they are I'm not sure I'd ever want to
use one again.
