Converting paint ball tanks for use on 3000 psi pcps.

[SH95503]

I purchased a chrome-moly steel 12oz paintball co2 tank, I want to use it on my pcp that has a 2900 psi fill, can anyone tell me if this tank will hold 2900 psi. I'm buying a fill station valve that is rated to 4500 psi that will screw into this tank. I know that this tank is a lot heavier build then the pressure tank on my Hatsan Flash and it holds 2900psi.

Thank you.

Take a picture of the markings on the cylinder so it can be interpreted. Typically CO2 tanks aren’t that high in pressure.
Also, if you fill it to 2900 and your Hatsan is a 2900 psi tube, you won’t even get a full fill even on the first time.
You need a carbon fiber 4,500psi tank.

Arn't CO2 tanks rated for 800 PSI? Even given a safety factor I'd not try filling one to 2900 PSI!

Why bother? Sounds like an unneeded recipe for disaster.

The burst disc in a CO2 tank is 3k. So, yes it will hold 2,900 psi.

Working pressure for a 3K burst disc is 1800psi.

The burst disk in my 4500psi tank is 7500psi, but working pressure is 4500.

Cylinder should have a PW (pressure working) of 124bar which is approx. 1798psi

The burst disc is on the valve. I'm changing the valve to a 4500psi fill station valve therefore the burst disc should be adequate for 2900psi. The question is will the tank itself hold 2900 psi with out any problems.

NO, read what I posted about working pressure. For that tank it will likely be 1800psi (it should be stamped in the tank near the neck. This is the MAX pressure the tank should be used at. Will it hold it? Likely for a while, but not likely "without problems" in the future. Do it at YOUR own risk. Your burst disc should be "sized" for the pressure vessel. Kinda like saying "Will my 120v circuit, wired with 14 ga wire, be suitable for something drawing 35 amps I'm putting a 40amp breaker in the box"

I probably wouldn’t use a co2 cylinder but that is just me.

DO NOT do it! Recipe for disaster. Get a tank that's rated for the intended pressures you need. Don't ask for trouble in the name of saving money. Not worth it.

Thank you all for answering my question.
I guess the safest thing to do is save my money and buy a hpa tank.Would have been nice to be able to use a 5 dollar tank to carry when I go hunting. Back to the hand pump for now, awkward to carry while hunting but doable.

Thank you all and have a nice day

As I mentioned in post #2, post a photo of the markings on the tank and we most likely can advise you definitively as to the operating pressure of the tank. But being CO2, it’s highly unlikely it’s capable of 4,500 without potentially being a bomb.

*or even 2900psi

Plus a paintball co2 tank will give you like no fills.
