An argon adapter is a high-pressure brass fitting designed to connect argon gas cylinders, regulators, flowmeters, or torches when their thread sizes or standard fittings do not match. Since argon is an inert gas widely used in TIG/MIG welding, shielding applications, and laboratory environments, these adapters ensure a gas-tight, leak-free connection under high pressure (typically up to 3,000 PSI).
