WESAW-15A - Western Enterprises AW-15A Inert Gas Adaptor, 1/4 NPT Male to B-Size Female

Precision Engineered Inert Gas Adaptor

The Western Enterprises AW-15A Inert Arc Adaptor is a critical component for industrial gas management systems, specifically designed to facilitate the connection between rigid piping or equipment ports and flexible gas hoses. Engineered with precision, this adaptor features a 1/4-inch National Pipe Taper (NPT) Male thread on one end and a B-Size 5/8-inch-18 Unified Fine (UNF) Right Hand Female thread on the other. This configuration is standard for adapting equipment with NPT ports to accept standard inert gas hoses used in welding and laboratory applications.

Material and Durability

Constructed from high-grade brass, the AW-15A offers superior durability and resistance to corrosion. Brass is the material of choice for gas fittings due to its non-sparking properties and ability to withstand the rigors of industrial environments. The fitting is machined with a 3/4-inch hex body, allowing for secure tightening and loosening using standard wrenches without the risk of rounding off edges. With a weight of approximately 0.109 lbs and a length of 1.471 inches, it is a compact yet robust solution for gas train assemblies.

Technical Specifications and Compliance

This adaptor is rated for a maximum pressure of 200 PSIG, making it suitable for a wide range of low-to-medium pressure applications involving inert gases such as Argon, Helium, and Nitrogen. It conforms to CGA 032 standards, ensuring compatibility with industry-standard connections and minimizing the risk of leaks. The Right Hand (RH) thread designation on the female side specifically indicates its use for non-fuel gases, preventing accidental cross-connection with fuel gas lines (which typically use Left Hand threads). This safety feature is paramount in mixed-gas environments where maintaining the integrity of gas lines is essential for both process quality and personnel safety.

Industrial Applications

In MRO (Maintenance, Repair, and Operations) settings, the AW-15A is frequently utilized to retrofit regulators, flowmeters, or welding machine gas inlets that are equipped with NPT threads. It allows these components to interface seamlessly with standard B-Size hose nuts, providing a versatile solution for facility managers and technicians maintaining complex gas distribution networks.
