WESAW-15 - Western Enterprises AW-15 Brass Adapter, 1/4" NPT Male x 5/8"-18 LH Female

Western Enterprises AW-15 Inert Arc Adapter Overview

The Western Enterprises AW-15 is a high-quality inert arc adapter designed to facilitate secure connections in industrial piping and welding auxiliary systems. Engineered with precision, this fitting serves as a critical bridge between standard piping infrastructure and specialized equipment requiring Left-Hand (LH) threaded connections. The adapter features a 1/4" NPT Male thread on the inlet side and a B-Size 5/8"-18 Left-Hand Female thread on the outlet, making it specifically tailored for applications involving water and industrial air.

Constructed from robust, free-machining brass, this component offers excellent resistance to corrosion and mechanical wear. Brass is the material of choice for these applications due to its durability and ability to maintain a tight seal under fluctuating thermal conditions. The unit is rated for a maximum working pressure of 200 PSIG, providing a substantial safety margin for standard cooling loops and shop air lines. The inclusion of a 3/4" RC Hex body allows for the application of precise torque during installation, ensuring a leak-proof seal without damaging the threads.

This adapter conforms to CGA 033 standards, designating its suitability for water and industrial air service. The utilization of a Left-Hand thread on the female side is a critical safety feature, designed to prevent the accidental cross-connection of water or inert air lines with fuel gas or oxygen systems, which typically utilize Right-Hand threads. This segregation of connections is a fundamental safety protocol in welding and industrial environments.

Weighing approximately 0.102 lbs and measuring 1.471 inches in length, the AW-15 is a compact yet essential component for maintenance, repair, and operations (MRO) professionals. Whether integrating a new water cooling system for TIG welding torches or configuring pneumatic lines in a laboratory setting, this Western Enterprises adapter delivers the reliability and compliance required for professional-grade installations.
