    Hi

    I wonder if someone will be able to help me on this?

    I managed to put together a paintball CO2 setup after a lot of research and sourcing of parts , this is what i have.

    Now the question is....

    Will this be safe to use and will the parts be able to hold the pressure (800 to 900psi) as the guy at the gas shop told me the unit that screws into the regulator is not that strong and he doesn't know if it will be able to hold the pressure?

    The regulator i have is a O2 regulator and i see the tank pressure on the gage is 28000 kpa max and working pressure is 300 kpa max. Seems like O2 works with higher pressure than CO2. Wil it work?

    Sadly i couldn't get hold of a 24oz tank, apparently they do not make them anymore as per the lady at the paintball shop. I did manage to get a on/off valve wich will replace the standard pin valve.

    Here is how the whole setup fits together.

    Any assistance will be appreciated.

    I know that generally using regulators on gasses other than intended is a big no no.. However, I'm not aware of any particular issues with using a O2 regulator on CO2..

    As far as i understand it will work but the regulator can not be used for O2 after its been on a CO2 tank. Im concerned about the temperature, as CO2 drops the temperature and i dont know if the O2 regulator can handle it or will operate in cold conditions. Eks bietjie dom met die goed.

    I'm not familiar with that regulator but doubt you'd have any issues. You may have to put some threadlocker on the connectors though to prevent leakage.

    Thanx RC will do so and see how it goes, will add a solinoid aswell. Just a dumb question will i be able to change the gages with ones that is suitable for lower pressure?

    The gauges? It won't make any difference other than be easier to read (for our application) in PSI or Bar, than having to convert from kPa.
