Very courios about this....

[Benfica4ever]

I was bored and started to wonder what would happen if you filled a co2 tank with n2 or if you filled a n2 tank wit co2?

[spider54]

... cant fill a co2 with nitro (no fill nipple) a nitro tank u can fill with co2 it works and is just a bigger co2 tank...

[Benfica4ever]

Ok, thanks.
I was just wondering.....

[street1356]

i too have wondered this


and could u switch the heads on a co2 and h2 tank

[Mossman]

most co2 tanks are rated for 1800psi i believe.

[CameraGuy]

I've read of people putting regs on CO2 tanks and using them as 1800 PSI air tanks (I believe that's the max rated working pressure for most/all paintball CO2 tanks, anything higher would be asking for the tank to blow up in your face).

As for using air tanks for CO2, it wasn't unusual a few years ago to run a 68 or 88 fibre tank filled with CO2 on Shockers because they're such gas hogs. I can't recall exactly how many ounces a 68 cubic inch tank will hold, but it's considerably more than a 20oz tank. You just can't switch back and forth between CO2 and air in a fibre tank, because the chilled CO2 can cause the fibre to delaminate from the inner metal tank, causing an explosion hazard when the tank is filled to 3000+ psi.

i think a 68 ci tank is supposed to hold 33 ounces.

[EsPo]

I would think eventually that co2 would bust the o rings in N2 regs...or the 'seals' if you prefer.

[edweird]

ive been "told" ... (ie take this as seriously as you want)

that once you put CO2 in a HPA tank you basicly just screwed the pooch on it and bought yourself a 400 dollar Co2 tank as it has a chance to perminatly screw up how the tank can reliably store HPA

[Muzikman]

Ed, It has to do with the temp changes. Chilling and warming a fiber wrapped HPA tank will cause the aluminum liner to pull away from the fiber. Just not a good thing to do.

There was a trick when HPA first came out to add a little CO2 to your HPA fill.

[xatle]

fiber wrapped tanks really should be made with titanium liners instead of aluminum.
unlike aluminum, titanium expands and contracts at very nearly the same rate as carbon fiber, taking care of the delamination problem.
too bad Ti is so spendy huh.
