Should do but maybe Mario could advise if there's any significance on the US CGA 320 description. Not sure if there is a us and uk thread.Quote:

Worst thing happening is that you have to replace the connecting nut to the CO2 tank.
The pin valve/paintball tank connector is international.
thinking about the price of stuff I may use my 20 oz tank as a buffer and get a 1kg/600g fire extinguisher as the main tank.
What kind of fittings do fire extinguishers have as there output?
20oz=600gram. Is almost 1 liter of volume in the bottle. How big a ram are you planning to use?
Straight from Woodies CO2 info site.

Throughout the world, carbon dioxide cylinder valves have a special thread. In Europe, Africa and much of Australasia, the thread conforms to British Standard 341 Part 1 (.860 in x 1/14 in W) or the direct European equivalent (DIN 477, SN 219505, etc). These threads are in effect interchangeable.
British BS341 No. 8 European DIN 477 No. 6 and SN 219505 Type 7
French NF E 29-650 Type C Australian AS2473 Type 30
America CGA 320 and Japanese JIS B 8246 CO2 threads are different and are not compatible with each other nor with British/European CO2 threads).

63mm bore 75mm stroke
the ram volume is 0.23l, so a 1l fire extinguisher would do nicely all be it a bit ott. if i were you i'd use the 600g co2 tank for the main tank and either a 12oz bottle for buffer or a small dry powder extinguisher
I could swap the pin valve for the extinguisher fitting.
The car-powder extinguisher is a tad oversized. A 12Oz paintball bottle overly heavy and small for the application.
Also, a .23L volume ram uses 2.3 liters of gas at 140 psi/10bar(max working pressure for mainstream pneumatics, and I would advocate using 100-110 psi/8 bar).
A 600 gram(20oz) bottle contains 300 liters of gas. That should give you 80 useable shots.
With a 12oz, that still is 40 shots +.

Swapping the pin valve with a normal CO2 valve ain't that easy, as the foot of a normal CO2 valve is or 4/3 BSPT, or M25*2, The paintball bottle uses 5/8 UNF as neck tread.
Nothing a lathe can't solve tough.
The valve off an Aquarium co2 cylinder has a smaller thread and thus requires less machining.[attachment=0:2x8j5ngw]valve.JPG[/attachment:2x8j5ngw]

would this bottle screw directly onto the regulator?
