Imagine you have a 48 cubic inch paintball tank.
If it's pressurised to 3000 psi, but the regulator is set to 500 psi, then it's just like having a (3000 / 500) x 48 = 288 cubic inch tank at 500 psi.

I want to get the clippard sm-3-3 air cylinder. However the rear mount on this cylinder is a 10-32. Does anyone know where to get an adapter for this (metal adapter not pvc) to fit onto any standard pipe size. Also it says the bore size is 5/32, which would fit in a .18" barrel, but a #10-32 thread is slightly larger than .18. AP would it fit in my barrel or not.

I just bought a clippard sm-3-3t air cylinder. I was hoping I would be able to stick a magnet on the end of it, so it would keep ky bbs from falling out. However, it turned out that it was aluminum and therefore not magnetic. I tried to drill a hole in the magnet, but that didn't work at all and made the magnet very weak. Does anyone have any suggestions. I don't have to put a magnet there, but that was the only way I could think of that would hold the bbs in place. The air cylinder has a threaded #0-80 rod (which is like .6 inches). Does anyone have any suggestions on how to connect a magnet to the air cylinder (my barrel is .18") or have any other suggestions on how to keep the bb from falling out when you shoot down.

I thought of using epoxy, but I wasn't sure about how it would hold up with pressure over 500 psi

JSR gonna cry if he sees that, if you rough up both the magnet and rod let it cure for a FULL 24hr it will stick.

Look at the rating of the epoxy that you are using, the locate brand ones are rated up to 2500psi

That is Probably shear strength not pressure rating, the pressure rating entirely depends on the materials you are bonding and the thickness of the joint.

it's a universal valve (both nc and no)

So would it work

yeah it has 3 ports so I concluded that it must be a universal valve - most NC only valves have just two threaded ports and a third one that's just a vent hole
