When I was searching for a way to fill my cannon on the go I was looking at one of these http://www.qindustries.net/products/hv_50.htm It's a little more heavy duty and yet still small enough to carry. But in the end I decided to go CO2 it just easier and faster.

I use those foam noodles you buy for swimming pools they work great for wadding plus they come in many sizes and are cheap, just cut them into 2" lengths. You can get like 36 plugs out of a 6' noddle for less then $5.

That price is for a new 5lb tank and we pay a 14% tax here in Canada. If you look on eBay 5lb tanks go for $60 to $70 American.

For such a small air chamber I would just go with a bike pump. I was pricing out CO2 tanks before I got a 20 pound tank for free. They are not cheap a 5 pound tank was going to run me close to a $100CAD after tax.

Mystery solved the valve is a CGA 320 as Da Pneu Kid suspected it was

The new adapter fits like a glove :) Thanks everyone for your help

Now I just need to buy my fittings and I'm good to go well that is when I can afford them :( I can't believe what they charge for a 4" SCH80 end cap $40 ...

Sorry I just worded it wrong, it's delivery pressure range is 0-1500 PSI

According to Harris web site it's rated to handle 0-1500 PSI

My regulator problems are solved I picked up a Harris 8700 high pressure regulator from work. It's rated to deliver output up to 1500 PSI, would love to see a pneumatic cannon that could shoot at 1500 PSI that would be insane. I still need to change the hookup to connect it to my tank, I'm going to ...

Thats cool if I can use O2 regulator because I know where there is one in the plant and it's just like new. I think the intake gauge reads up to 4000psi but I think the outlet gauge only goes up to 100psi. Can I change the gauge to one that reads say 200psi or does it not work that way.

I think my ...

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

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

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 ...

@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 ...

Here are a couple screen caps for you to look at

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 ...
