I want to be able to start airing down my tires when I go offroading so I need something to fill them up again when I head out on the highway... my truck is my daily driver.

I have looked at portable CO2 systems that retailers sell (on the web) and they seem pretty expensive. Couldn't I get the tank (perhaps used?), valves, fittings, hose, etc myself and put it all together?
If yes, my problem is that I don't know exactly what I need as I've never seen one close up.... and where would be the best places to get the stuff I need?

Is there an article somewhere here that tells me how to go about doing this? I did a search by typing in CO2 but the search engine doesn't accept that cause the word is too short. Help. Please.

Go to a welding supply house where they can set you up with a bottle and a reg. You can get regs in adjustable or like I used 125psi Then just hook up a chuck. Pretty simple.

get a non-adjustable hyperflo valve (a shitload of venders carry them) they are pre set to 150psi, if you need a adjustable gauge/psi for airing up just get a cheap regukar air regulator from harbor frieght and but an air chuck on it so its removable.

a remaining pressure gauge on a CO2 system is kinda worthless as it will show full till its almost empty.

buy a bottle off ebay. aluminum will be lighter,steel cheaper, or check you local gas shop /beer vender

get a non-adjustable hyperflo valve (a shitload of venders carry them) they are pre set to 150psi,

Will this be a welding supply? Or someplace like Mcmaster Carr?

Thanks

nope, any decent off road shop :flipoff2:

they are made by The Source, search in google for hyper flo regulator or hyperflo regulator and check with some vedors here. they are simple bare bones non-breaking shit. pre-set at 150psi. like $25 for the one that is a 90 degree outlet and $35 for the one in the pic

The static reg pictured above is the cheep one to get.

For a tank the cheepest way to go by far is to call your local pepsi/coke distributor. They will give you one for a deposit and can refill or exchange after that.

I can get the big tank from my pop distributor in town for a $20 deposit and then exchange it for a full one for $12.

Stop by harbor freight and get a hose and a tire filler and a couple quick releases and you are filling tires like a fool for well under $100.

these guys have good regs and hoses:

Any horror stories about these tanks, I want one but something about all that compressed CO2 bouncing around on the trail kinda sketches me out. I would hate to roll and have my roll bar save me but have the tank explode and kill be because it hit a rock or something.

How safe are these?

That's whu you mount it, kinda like a fire extiguiser mount.

Yo don't want ANYTHING loose in your rig.

It wont explode like in the moives .........

........ it will be more like a SCUD missle :D

I have a regulator from HERE (http://www.williamsballoons.com/html/carbon_dioxide.html)

I have the 150PSI model. Fills tires quick, reseats beads easily, and I don't object to running air tools with it.

If you were to rupture the tank it would not explode. In short, all of the contents are not available at once to become a gas. It has to evaporate gradually to make a gas. Done too quickly (like rupturing the tank) will autorefrigerate the contents, freezing the liquid CO2 solid. But it could still kill you in short order by asphyxiation.
Don't overfill the tank. This will cause the safety valve to pop and could asphyxiate you. A smart man would roll down a window and exit the vehicle as soon as possible. :grinpimp:

is running 150 psi through air tools designed for 90-100 psi real bad for them?

i run 150 psi thought all my air tools at my shop and have never had a problem with them

FYI, I had a tire chuck explode and shoot half the parts inside it just past my arm when I was running it as 120psi (rated to 90)

Scared the shit outta me. Now all my stuff gets run at 90 :laughing:

That sounds fun!! :D

No shit you don't want something loose in your rig.
You ever rolled a truck? Things have a tendency to get loose no matter what. And a rock can most certaintly hit the tank still mounted or regulator and be like a bullet for either you or any other bystanders. Hate to roll my truck and shoot my spotter all at the same time.


4mogger- That is way to much knowledge for me, Is this why they use CO'2 instead of nitrogen/oxygen mix like a scuba tank. B/c i know those can rupture meaning shooting the top off and kill you. Or is b/c you can compress CO'2 more. Also doesn't CO'2 expand alot more than Air when heated.
How many PSI are these bottles holding.

You use CO2 because it is stored in the tank as a liquid, and must evaporate into a gas as you use it.
According to the first web site posted in this thread tank pressure is 800 PSI while there is any liquid left in a tank.
Nitrogen or Oxygen in a tank is simply compressed, around 3000 PSI when full.
Much higher pressure, and since it is alredy a gas, all available for imediate release if the valve is broken off. That's why all tanks have the safty cap for when you move 'em.
