This brass cylinder adapter allows secure connection of a carbon dioxide cylinder (CGA-320) to a nitrogen regulator (CGA-580), providing a reliable solution when equipment has mismatched CGA thread types. Designed for safe, temporary applications, it boasts industrial-grade brass construction and precise fitting to accommodate a variety of gas control setups. Adapters should only be used for short-term purposes and never as a substitute for the proper CGA regulator on long-term installations, ensuring safe and dependable operation in laboratory, industrial, or maintenance contexts.
