CO2 quality is critically important for the health of an 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.
