How to Install a Anti-Siphon Kit in a Co2 Tank

Utilizing an anti-siphon kit in a CO2 tank can help improve the performance of a paintball gun. Without an anti-siphon kit, liquid CO2 may enter the paintball marker. This can freeze up the internal parts of the marker and prevent it from shooting. An anti-siphon kit prevents liquid from entering the paintball marker by angling a tube towards the top part of the CO2 tank. Since the liquid CO2 remains at the bottom of the tank, only gaseous CO2 will enter the paintball marker.

      Empty the CO2 from the CO2 tank. This can be accomplished by partially screwing it onto the air source adapter of the paintball marker. Slowly screw the CO2 tank until there is a hissing sound. The CO2 tank is empty when the hissing sound stops. This step is absolutely essential. If the CO2 tank is not completely empty, serious injury can occur.

      Remove the valve from the CO2 tank by placing it with the valve facing downwards into a table vice. Place a strip of rubber around the valve and tighten the vice around the valve. Be careful not to overtighten the vice. Turn the tank clockwise to loosen it from the valve. Gentle heat from the heat gun can help loosen the valve if necessary.

      Screw the CO2 anti-siphon kit into CO2 tank using the 7/8-wrench. It is important to fully tighten the valve to the CO2 tank, but do not force it. Overtightening the valve can damage the threads. Do not fill the CO2 tank for at least 12 hours. The lock-tite must dry completely prior to refilling the tank.
