WESQDB301 - Western Enterprises QDB301 Inert Gas Quick Connect Socket, Male Thread

Technical Overview of Western Enterprises QDB301

The Western Enterprises QDB301 is a precision-engineered Quick Connect Socket designed specifically for inert gas applications in industrial, welding, and laboratory environments. Constructed from high-quality brass, this fitting is engineered to withstand the rigors of daily use while maintaining a leak-proof seal. It features a B-Size 5/8"-18 UNF Right Hand Male thread, intended for regulator-to-hose configurations where a male thread interface is required on the socket side.

This unit is rated for a maximum working pressure of 200 PSIG and is compatible with inert gases such as Argon, Helium, and Nitrogen. A key technical feature is the integrated demand valve and reverse flow check valve mechanism. This system ensures instant closure upon disconnection or in the event of back pressure (as low as 10 oz), effectively preventing gas escape and reverse flow contamination. The component has been cycle tested to exceed 100,000 operations, indicating a potential service life of over a decade under normal operating conditions.

Safety is paramount in the design of the QDB series. The connectors are keyed specifically for their gas service (CGA 032 for inert gases), making them non-interchangeable with oxygen or fuel gas fittings. This mechanical lockout prevents dangerous cross-connections. The QDB301 is UL Listed and manufactured in the United States, meeting strict quality and safety standards for compressed gas equipment.
