QDB33 Argon Quick Connect Fittings — QDB300/QDB301 Inert Gas Regulator, 125 psi, Gold$$Garden & Patio

QDB33 quick-connect kit includes QDB300 male plugs and QDB301 female sockets for rapid, secure hookup to argon and other inert gas hoses. Maximum working pressure: 125 psi. The QDB300 regulator is designed for connecting argon/inert gas hoses. A spring-loaded locking mechanism engages with fingertip action to create a gas-tight connection, while the socket features a double seal socket connection on second seal for extra leak protection. Non-interchangeable oxygen and fuel gas connections and color-coded fittings help prevent accidental gas mixing and improve safety. These fittings assemble and release quickly with a simple press or slide motion; the reverse flow check valve can be completely closed instantaneously. Constructed from high quality brass, the fittings resist rust and corrosion, withstand high gas pressures, and are built for long service life.
