The 304 Stainless Steel CO2 Tank Adapter is a heavy-duty fitting designed to bridge a standard North American CO2 cylinder (CGA-320 thread) to a 1/4" MFL (Male Flare) connection. This adapter is the professional solution for applications that require a direct high-pressure line from a CO2 tank, such as tank-to-tank transfilling, specialized carbonation setups, or connecting high-pressure braided gas lines. Constructed from solid 304-grade stainless steel, it is engineered to safely handle the extreme pressures found in bulk CO2 storage.

Unlike brass adapters that can "gall" (seize) or corrode over time, our stainless steel version offers superior thread life and maximum safety. The CGA-320 female end is compatible with standard 5lb, 10lb, 20lb, and 50lb CO2 tanks, while the 1/4" MFL outlet allows for easy connection to common beverage gas hoses and swivel nuts. This fitting is an essential tool for brewery maintenance, allowing for the creation of custom gas manifolds or portable filling stations without compromising on structural integrity.

Safety & Installation Note: Because this adapter connects directly to a high-pressure cylinder, it must be used with a CGA-320 Nylon or Fiber washer (sold separately) to ensure a gas-tight seal at the tank valve. The 1/4" MFL side utilizes a standard flare seat, providing a reliable metal-to-metal connection for your downstream gas lines. This adapter is not a pressure regulator; ensure your downstream components are rated for the full pressure of the CO2 cylinder before use.
