co2 setup

Unread postAuthor: spudshot » Sat Jun 18, 2005 4:42 pm

DISCLAIMER: I must warn you, 800psi is nothing to mess with, its very dangerous stuff, and by reading further you take any and all responsibility for any and all injury, property damage, or death which may occur from the use of this setup, this is meant for informational purposes only, and is not meant to be duplicated.

So, you want to make a co2 adapter for your spudguns, but you don’t want to dump a hundred bucks on a palmer reg, or maybe you just don’t know how you’ll go from paintball threads to pipe threads? I’ll show you my way of making a spudgun regulator setup, which will cost you a fraction of one of those paintball regs. My entire setup cost me about 15 dollars (not including paintball tank) it all depends on where you can find your different parts. Lets start off with what you will need

<img src="http://mpg.cc/co2hookuphowto/universal-refill-adapter_large.jpg">

<img src="http://mpg.cc/co2hookuphowto/top-of-universal-refill-adapter_large.jpg">

<img src="http://mpg.cc/co2hookuphowto/asa-port-of-universal-refill-adapter_large.jpg">

you will need one of these, they are universal refill adapters which are commonly used on fill stations for co2, I picked one of these up for 5 bucks

<img src="http://mpg.cc/co2hookuphowto/tape_large.jpg">

this is a must, it’s a roll of Teflon thread seal tape which you can pick up at any hardware store for about 60 cents

<img src="http://mpg.cc/co2hookuphowto/regulator_large.jpg">

you will need a regulator to take the extreme 800 psi pressure of co2 down to the manageable 100psi that spudguns operate on. Its very important to make sure your regulator can handle 800 psi, this particular one is rated for 4000psi, you can pick up a bulk co2 beverage regulator for about 15 dollars on ebay, I got this one at a yard sale for 5 bucks. Now, not all regulators can be adapted in the same way, mine had ¼” NPT threads on the input side once I took off the tank adapter (thing on the right) therefore I just bought a high pressure ¼”-1/8” nipple from http://www.mcmaster.com , you may need to buy a different fitting, or even cut threads for yours to work.

<img src="http://mpg.cc/co2hookuphowto/regulator_large.jpg">

<img src="http://mpg.cc/co2hookuphowto/part1_large.jpg">

You will also need a special high pressure fitting that is rated to ATLEAST!!! 800 psi. in my case I needed a ¼”npt-1/8” npt nipple from mcmaster carr

Now for the instructions

<img src="http://mpg.cc/co2hookuphowto/remove-cover-from-eighth-inch-side_large.jpg">

<img src="http://mpg.cc/co2hookuphowto/put-teflon-tape-on-eighth-inch-side_large.jpg">

First, remove the cap from the 1/8” npt side of your high pressure fitting and wrap about 5-7 turns of Teflon tape to the fitting.

<img src="http://mpg.cc/co2hookuphowto/screw-adapter-into-universal-refill-adapter_large.jpg">
<img src="http://mpg.cc/co2hookuphowto/use-a-wrench-to-tighten-the-adapter_large.jpg">
Next, you will need to screw the 1/8” npt side of the fitting into the 1/8” port on the universal refill adapter, tighten it by hand first, then use a wrench to tighten it the rest of the way.

<img src="http://mpg.cc/co2hookuphowto/use-wrench-to-tighten-fitting-into-regulator_large.jpg">

Now take the cover off the other end of your high pressure fitting, and use 5-7 wraps of Teflon tape on this side as well, screw this side into your regulator, then tighten it with a wrench.

<img src="http://mpg.cc/co2hookuphowto/the-finished-product_large.jpg">

<img src="http://mpg.cc/co2hookuphowto/the-finished-product-2_large.jpg">

that wasn’t so hard now was it? now all you need to do is use any combo of fittings to get to your desired adapter on the output side, and get yourself a co2 tank and an O-ring. Your first test should be conducted very carefully, once the pressure is on spray soapy water to check for leaks, if it bubbles theres a leak.

Again, this is not meant to be copied in any way, this is very dangerous, I haven’t used it on my pvc guns yet because I’m afraid the pvc may become too brittle I’ve only used it on my steel cannon and my copper cannon.

this is a project for a VERY experienced spudgunner, anyone who hasnt dealt with high pressure before SHOULD NOT TRY THIS

a fitting from ace wouldnt work, they're not rated for 800psi that reg would probably work, though the auction ended :wink: the universl refill adapters can probably be bought from any pro shop, i got mine cheap because it was an extra they got when they ordered a replacement for the one on their tank fill station

for the univeral refill adapter could I just use the part of an old broken paintball gun's drop forward? I mean the part that you screw the tank into.
I would like a reg so that I could attach a grenade launcher (I make my own paint grenades) to the bottom of my paintball gun. I would wire a blowgun into the front handle and extend a hose to the chamber of the grenade launcher.

Sorry to kick up this post but..
I am going crazy searching the forum for a reference to a good reliable safe (but on the inexpensive side) CO2 Regulator.

Anyone have any ideas? I live in the US.

Thanks in advance.
You can submit links to other parts of the site or what you use. This will used with PVC so its important its reliable.
