I was in Walmart the other day and looking at their CO2 tanks for paint ball guns.  Now the question.  Has any one come up with a cheap way (about $30.00) to adapt one of these tanks for use to fill tires?  I've seen the $110.00 kit that includes a 20oz tank but right now it's too much for me to justify.  Although I wouldn't feel bad about a home-brew set up for under $60.00 total including the tank.  So what do I need to attach to the tank?  Adaptor?  Regulator?  Pressure gauge, manifold, etc, etc...

try a search for co2 at ack's FAQ... and thanks for suggesting more search phrases for this topic! 

The problem is the regulator. I haven't found a regulator that will fit a 20oz for less than a hundred bucks or so.

If anyone knows where there is one, let me know.

The instant air, for $110 is really a good deal. How much are the 20 oz tanks?? About $30, right? then a regulator for 100, then a hose, and a case, and a tire plugging kit, and a blow gun.. etc etc..


I wish we could find acceptable regulators for cheap... if ANYONE knows.. pass it along.


As it stands now, it is cheaper to find a 10# tank, and get a standard hi flow regulator from Outback air for $55.00, then you can put your own hoses on it.

Here is my 20#er.. but I am picking up a 10#er Friday, and a 50#er witha siphon for filling my 10#er AND my 20oz tanks, as well as the boys Paintball tanks.
