The threads are a good match with 3/4" BSP pipe fittings.

You're better off getting stuff from ebay though.

I'm guessing that even if I did use 4500psi (god forbid) with a 68ci tank, all of the air would not come out at once, it would just keep discharging for a few seconds? I am trying to figure out the maths behind it, I have done mathematical mechanics but only at basic levels; velocity, projectile motion, things like that.

If you poke a hole in a bucket of water, will it all come out at once ;)

You need to define what you want to achieve before thinking about the hows.

Is that your cannon? Impressive.
But I believe you are referring to the regulator thread size.
I was hoping to figure out a pipe system so that 4500psi would be realised at once, securely tied to the floor of course.

I meant the threads which are usually on the bottle where it hooks up to the paintball marker.

Some photos of your setup would help us help you.

Sorry for digging out
I made a PAC with a bottle of paintball and shooting at 3000psi (200bar), here's the link:
