WESB-72 - CGA-580 to 1/2" NPT Male Brass Cylinder Adaptor

Precision Engineered CGA-580 Valve Outlet for Industrial Gas Systems

The Western Enterprises B-72 CGA-580 Valve Outlet is a critical component designed for the safe and efficient transfer of inert gases in industrial, laboratory, and welding environments. Manufactured from high-quality brass, this adaptor is engineered to withstand the rigorous demands of high-pressure gas service, boasting a maximum pressure rating of 3000 PSIG. The unit serves as a bridge between standard cylinder valves and downstream equipment, ensuring a secure and leak-free interface that is essential for maintaining system integrity and safety.

Technically, the adaptor features a CGA-580 connection on the inlet side, characterized by a .965"-14 NGO Right-Hand Female thread profile. This specific geometry is the industry standard for Argon, Helium, and Nitrogen gas services, preventing accidental cross-connection with incompatible gases such as Oxygen or Carbon Dioxide. The outlet side is machined with a 1/2-inch National Pipe Taper (NPT) Male thread. The tapered design of the NPT thread allows for a tight seal when mated with corresponding female fittings, making it ideal for permanent or semi-permanent installations in gas manifolds, pigtails, and distribution piping.

The physical construction of the B-72 reflects a commitment to durability and ease of use. The body is shaped with a 1-1/8 inch hex cross-section, providing ample surface area for wrench engagement during installation and removal. This robust design minimizes the risk of rounding off edges and allows technicians to apply the necessary torque to achieve a proper seal without damaging the component. With a weight of 0.276 lbs and a length of 1.885 inches, the fitting is compact yet substantial enough to endure the mechanical stresses associated with connecting and disconnecting heavy gas cylinders.

Compliance and safety are paramount in gas handling equipment. This valve outlet meets the stringent dimensional specifications set by the Compressed Gas Association (CGA), ensuring universal compatibility with all CGA-580 cylinder valves. Whether utilized in a high-purity laboratory setting for chromatography carrier gases or in a heavy industrial facility for welding shielding gas distribution, this brass adaptor delivers consistent performance. It is free from hazardous materials that could compromise gas purity, although users should note standard Proposition 65 warnings regarding lead content inherent in free-machining brass alloys.
