A staple of the game of paintball for decades, the 20oz paintball CO2 tank offers plenty of shots per fill with compatible paintball guns like the Valken Blackhawk line, Tippmann 98, Tippmann A5, the Spyder or the GOG eNMEy line, and is a simple, affordable way to power your paintball gun for between 700 and 1000 shots! Equipped with a high-quality pin valve that will thread into a paintball gun's bottle adapter and a safety burst disk to vent the air in the case of overpressure in the tank, the Valken 20oz CO2 tank is an essential piece of paintball gear!
According to 49CFR 180.207, re-test year for a compressed air aluminum cylinder is 10 years and for CO2 is 5 years. There is no expiry date for these cylinders as long as they pass the retest requirements as shown.
