For use in paintball, a CO2 tank is fairly simple, consisting of an aluminum cylinder and a pin valve (usually brass). The pin valve depresses when you screw the CO2 tank in to your paintball gun, allowing a free flow of unregulated CO2 into the gun (usually about 800psi). Many guns use a simple valve system to control the gas flow and fire paintballs, but more and more, paintball guns are being sold with regulators, to better control the consistency and pressure level of the gas inside the marker. These CO2 tanks have several safety features, as well.
1800psi Burst Disk - If the pressure inside the CO2 tank exceeds 1800psi, a burst disk will safely release all the air out to prevent a possible rupture. Possible causes would be leaving your tank in direct sunlight, allowing the gas to expand.
Excessively strong aluminum cylinder - These tanks are rated at over 3000psi rupture ratings. Long before pressure inside the tank could reach a dangerous level, the 1800psi burst disk will release the pressure out.
Simply screw the CO2 tank into your paintball gun, and you're ready to go
Note - CO2 tanks are not recommended for electro-pneumatic paintball guns. If you have questions regarding what tank you should purchase for your paintball gun, please give Hustle Paintball a call.
