CO2 quality is critically important for the health of your air gun. Without clean, reliable Umarex CO2 power, air guns can break down. Valves clog. O-rings and seals deteriorate. While manufacturers meet standards of size and weight, they aren't held to exacting standards for cleanliness. Even the designs of the seals at the top can vary from one maker to the next, and, if a neck seal is out-of-spec, it can damage a gun's puncture assembly. Ensure a lifetime of performance with clean CO2 powerlets and cartridges. Umarex makes 88 gram CO2 cylinders, and 12 gram CO2 capsules, too. They are all tested and proven clean and fit most brands of CO2 airguns. The Paintball, Airsoft, and BB CO2 cartridges are a great way to ensure a steady air supply for your paintball gun. Featuring a unique thread pattern and a secure seal for safety, these cartridges are a reliable source of power for an enjoyable game. Don't miss a beat in your games!
