What type of valve connection is on my CO2 tank

[Technobob]

I'm new to pneumatics so I don't know all the different connections can someone tell me what this connection is called.

[frankrede]

I have never seen anything like that, do you have anymore pics or info?

[Technobob]

I got this tank from work, they were going to toss it out because no company laid claim to it after the plant closed down. So I grabbed it for free and it's almost full.

The reason I asked is my boss gave me a Argon regulator (again for free), he said it will work with CO2 but the connection is the wrong type.

[cdheller]

If my memory is right it's a 1/2 in pipe thread that is not tapered.
It seals on a gasket in between the gauge connection and the bottle.

a welding supply store should be able to change your gauge inlet fitting( fairly cheaply (not for free though)

There goes the idea of a completely free cannon.

Is the hole in the middle also threaded?

[Technobob]

@cdheller

The connection measures 3/4 of an inch

@From_Hamsterdam

Yes it's threaded in the center and it's 1/4 of an inch

@TwitchTheAussie

Ya I was so close to a free cannon I managed to get most of it from work, here is what I received for free so far and no I did not steal any of it.

2x3" SCH80 90º Elbows
6 Feet of 4" SCH80 pipe
3 Feet of 3" SCH80
6 Feet of 2" SCH80
1 10 foot coiled air hose
1 20lb CO2 Tank
1 Argon regulator
1 Asco Red Hat 2" piston valve with a rebuild kit
1 Blow Gun
1 Pressure gauge
and finally all the air connections I needed

Just a few more to be had and I'm ready to fire me some potatoes

[chaos]

ya wanna post some pics of all that so i may stare at my screen for a few minutes?lol

Here is a pic for ya the piping and air hose is still in my office at work.

When I was getting this stuff out for the pic I had forgot I also have some parts for more cannons that I also got for free (I really love my boss really great guy). After all the big daddy cannon is going to need a wife and kid

hmmm i being a welder myself suspect that the regulator for "argon" will not work for you.

argon regulators usually regulate lpm (liters per minute) not pressure (kpa, psi ect.

but damn nice valves n stuff u have there and u seem to have more than enough gauges also.

good score

Can you tell anything from this photo? the valve has no info on it other than max inlet 3000psi

[chaos]

yer it will work at 2500psi (maybe a bit higher) 3000psi is on the limit. i got two of these here at mi house one is on an argon bottle, these regulators only control flow, not pressure. soz but you might want to get a different regulator. HERE is a regulator for both CO2 and Argon but as i say again it only controls flow not pressure. your Regulator will display the correct pressure in the tank but will not give you any useful pressure for a pneumatic gun.

If it only controls flow you could make a super high powered vortex BB gun.

If it only controls flow you could make a super high powered vortex BB gun.

man if only that was true.... 30lpm is crap all (i could blow harder than that) nice idea though.

[Technobob]

Well that sucks

Can you use a oxygen regulator with CO2? thats about all that is left at my work, they sold the welding department a couple of weeks ago.

Back on topic still looking to identify this valve on my CO2 tank
