Over 200+ shots from my 1350 psi reg setup

Well Sure, tank ratings are generally 1/6th of actual fail pressure giving you a 600% fail safe. Im just saying I would not risk it. granted 4500 is only 150% of 3000 but it still seems sketchy to me. However I tend to lean to the side of caution.

Oh ok. I was unclear. sorry bout that. as for the material i am not sure. If I had to guess though i would think the valve would fail before the adapter itself. but that is again just a guess. however also remember that the AF tank side of the clamp should never exceed 3000psi due to the tank ratings. So im not sure if they design the adapter on the clamp to operate at those pressures.

Savage, the part of the scuba clamp that I believe you are refering to is simply an adapter to attach the bottle to the clamp itself. The CO2 adapter is a little more complicated in that it houses a valve very similar to the valve attached directly to any AF tank. So essentially the CO2 adapter is a way to install a AF valve on a CO2 tank. Or in this case a regulated HPA tank used for paintball guns.

Would someone please compare the part of the scuba clamp that looks like the Co2 adaptor, to the Co2 adaptor? They look the same to me.

A normal 4500psi paintball tank filled to 3k psi with the co2 adapter? Won’t damage the adapter? Consistent 800fps on .22 caliber for close to 200 shots? This would be good news since i might be shooting in cold weather and dont want the hi flow tank on for 1000fps+ speeds… I’m very interested in the idea. 😀

best I remember (when I saw a friend’s benji tank) is they are about the length of a 20oz co2 bottle and somewhat larger in diameter. don’t remember the exact size but thats a good approximate

Thanks YN, that is what I wanted to know. A regged system is usually discussed in terms of shots ‘on reg’ as after that is anyones guess as to performance.
Joe, if you have a bottle guage then a chrony of the last few shots before 1350psi down to say 1300psi would suffice to know how it reacts at the switch from ‘on reg’ to ‘off reg’.
Likely say 150 shots on reg would be pretty cool.
Walter…
BTW deviation should be in the 2-3fps while on reg if shooting volume is well matched to your power output. If you get hot shot then a slower one than back to full speed the shooting volume is too large for the reg to sense the drop in pressure. The regged volume must deplete low enough to allow the reg to sense the drop and replenish it to the 1350psi.
Cheers,

Here an example of what you “might” expect on a tank that is filled to 3000 psi with a 1500 psi regulator just to help illustrate my comment above.

Start pressure – 3000psi

1- 900
2- 899
3 – 900
4 – 901
5 – 900
6 – 900
7 – 898
8 – 899
9 – 901
10 – 880 * Pressure now below 1500 psi – Gun is “OFF REG”
11 – 800
12 – 700
13 – 500

As you can see, shots 1 through 9 are all very close (must be a small tank 😉 ) indicating that the pressure in the tank for those shots was higher or equal to 1500PSI (Regular pressure). Shot 10 drops by 20 fps and each shot after that drops by even more indicating the gun is now shooting “off reg” meaning the pressure has dropped below the level at which the regulator operates on.

Walter is just interested in shots 1 through 9 and doesnt care what comes after that as they arent really usefull shots because they drop so sharply.
