WESAW-18 - Western Enterprises AW-18 Brass Inert Arc Nipple, B-Size, 3/16" Hose Barb

Technical Overview of the Western Enterprises AW-18 Inert Arc Nipple

The Western Enterprises AW-18 is a specialized inert arc nipple designed for the precise requirements of industrial welding and fluid transfer systems. Manufactured from high-grade brass, this component ensures long-term durability and resistance to corrosion, making it an ideal choice for environments involving water, industrial air, and inert shielding gases. The unit is precision-machined to meet strict tolerance standards, ensuring a secure and leak-free fitment within pneumatic and hydraulic circuits commonly found in welding setups.

Technically, the AW-18 features a B-Size nut configuration with 5/8"-18 UNF threads, a standard specification for many regulator outlets, flowmeters, and machine connections in the North American market. The barb end is engineered to accommodate a 3/16-inch Inner Diameter (I.D.) hose, providing a tight friction fit that, when secured with an appropriate ferrule or clamp, withstands pressures up to 200 PSIG. This pressure rating is sufficient for the vast majority of shielding gas delivery systems used in MIG and TIG welding, as well as recirculating water cooling lines for high-amperage torches.

This component is compatible with CGA 032 and CGA 033 connection standards, further broadening its utility across various gas service types. The brass construction not only provides mechanical strength but also ensures compatibility with non-corrosive gases and cooling fluids, preventing contamination of the weld pool or degradation of the cooling system. With a total length of approximately 2.228 inches, it provides ample shank length for double-crimping or secure clamping.
