Technical Overview of the Western Enterprises AW-431

The Western Enterprises AW-431 is a specialized Inert Arc Hose Coupler designed for industrial and welding applications requiring secure fluid transfer. Manufactured from high-quality brass, this fitting is engineered to withstand the rigors of heavy-duty environments while maintaining a leak-proof seal. The unit features a B-Size configuration with 5/8"-18 UNF Left Hand (LH) Female threads on both ends, making it specifically suitable for joining two male LH fittings or hoses.

This coupler is rated for a maximum pressure of 200 PSIG, accommodating standard requirements for water cooling systems and industrial air lines. The body is machined into a 3/4" RC Hex shape, providing ample surface area for wrench engagement during installation and removal. With a total length of 1.510 inches and a weight of approximately 0.106 lbs, it offers a compact yet sturdy solution for line extension. The use of Left Hand threads is a critical safety and organizational feature in welding setups, often designating water or fuel lines to prevent cross-connection with shielding gas lines (which typically use Right Hand threads). This specific model is designated for Water and Industrial Air service.

Western Enterprises is known for precision manufacturing in the gas and welding industry. The AW-431 adheres to strict dimensional tolerances to ensure compatibility with standard B-Size fittings. Whether used in a laboratory setting, a welding shop for TIG torch coolant lines, or general industrial air distribution, this brass coupler delivers consistent performance.
