We only sell and use disposable, one time use, metal, threaded (3/8″ by 24 threads per inch) Co2 cylinders. Our Co2 cylinders are relied upon world wide by the FAA (Federal Aviation Administration) and SCUBA divers for life vests. They are the most reliable Co2 cylinders made in the world! When you put your professional reputation on the line (or your life if a SCUBA diver), you want a Co2 cylinder that will work perfectly.
As an additional safety measure, these are screwed into a metal sleeved release mechanism firmly attached to our launchers by a custom made machine bolt. Using any other brand of Co2 cylinder will void your lifetime warranty on all SEI’s Launchers and Cannons. These gold colored cylinders are engineered to work with our launchers. The welded cap is concaved to guide the piercing pin to dead center. Our cylinders are manufactured to stringent military specs. The filled cylinders are heated to a high temp for an extended period of time to ensure there are no leaks. These are food grade as used in seltzer making machines, soda dispensers, and home beer brewing. They are even used in the medical field.
These Co2 cylinders are for a one-time use and are non-refillable
Keep in mind, other cylinders, might cause the pin to hit off center and create a misfire. The launcher’s internal piercing pin might also be damaged if an off brand cylinder is used.
