CO2 Canister Adapter

Unread postAuthor: MrCrowley » Sat Mar 24, 2007 7:51 pm

Alrighty Ill get straight to the point...

I need an adapter that you can attach a 12gram or 16gram CO2 canister on one end and have normal BSP or NPT threads on the other. As long as the adapter can use either threaded or non threaded 12gram or 16gram canisters and prefably 1/8" or 1/4" male or female threads on the other end(or paintball tank threads as long as they're NPT or BSP so I can use them with brass fittings)

ive found only one possible adapter but im confused with how it works.

https://www.palmer-pursuit.com/ecom/pro ... 737c6ab195

Im confused on how it punctures the 16gram canister without letting all the CO2 out when your threading the the canister onto it? And if it doesnt let all the CO2 out how do you make it?

You probably want this, it only works with 12 gram and is designed to fit on a paintball gun.

Both of them are too big,needs to be small like the brass adapter I posted. For got to mention that,they can't be those bike inflators or those paintball ones which can adapt to be a stock. Also the one scope posted is $25US and they wont me to pay like $60US for shipping. Does anyone know anything about the one I posted?

The one you found i believe is just for threaded 16g cartages.. it has a piece of metal in side it that will pierce the cartages... there aren't any smaller ones for non threaded 12 grams because they put the pressure on from the back...

So I could use the one I found? What happens when you thread the canister in? Does it leak pierce it straight away? So I could attach the 1/8" side to a 1/8" ball valve, close the ball valve and thread on the 16gram CO2 canister and it should be fine? If anyone knows any other similar adapters please say so :P

It also has the option of 'Back check' for an extra $3....
What is back check?
Is it just another name for a check valve?
Would it be better to have back check?

MrCowley, first off 16 grams are hard to find and more expensive($1.50US compared to $.50US) than 12 grams.And second they are the same size as the 12 gram changer Orpackrat suggested.So all you have to do is get a 12 gram changer and the constant air adapter from a paintball gun,screw it together and add a 1/8"ball valve.The air adapters are threaded for 1/8" outlet.And yes International shipping is a pain.

even with the right adapter to go from a CO2 tank, of any size, to common pipe thread, to use in a regular pneumatic gun, say 100-125 psi, you would still need a regulator for that, correct?

yup

if your chamber is big enough to eat a 12g to a reasonable pressure, then your good.

it depends on the size of the chamber, and the type of tank, and the temperature... if your using anything above a 3 oz tank then yes i would say use a regulator... but for the 12 and 16 and 9g disposable ones... you can check your size of your chamber to the chart... search for co2 pressure chart.. and have safe pressures
