WESAW-14A - Western Enterprises AW-14A Brass Inert Gas Nut CGA 032

Reliable Gas Connections for Your Welding Rig

Every welder knows that a quality weld starts with consistent shielding gas coverage. If your gas connections are leaky or worn out, you risk porosity, oxidation, and a lot of wasted time grinding out bad welds. The Western Enterprises AW-14A Inert Arc Nut is the heavy-duty brass fitting you need to ensure your gas delivery system is tight, secure, and reliable. Whether you are setting up a new TIG machine or replacing a stripped nut on your MIG wire feeder, this component is built to last.

Why Brass Matters
In a busy shop, equipment gets banged around. Plastic fittings can crack, and cheap alloys can strip out, leading to frustrating leaks. This nut is machined from solid brass, giving it the strength to handle repeated tightening and loosening. Brass is also naturally resistant to corrosion, meaning it won't seize up or degrade over time, even in humid shop environments. It’s the industry standard for a reason—it works.

Perfect Fit for Inert Gases
Safety is paramount when dealing with compressed gases. This nut features the standard CGA 032 connection with 5/8"-18 Right-Hand threads. This specific design is intended solely for inert gases like Argon, Helium, and Nitrogen mixtures. Because the threads are specific to this gas family, you don't have to worry about accidentally hooking up a fuel gas line to your shielding gas inlet. It’s a simple, fail-safe way to keep your shop safe.

Easy Installation
Nobody likes struggling with rounded-off fittings. The AW-14A features a crisp 11/16" hex shape that fits your wrench perfectly, allowing you to get a snug seal without slipping. It is rated for up to 200 PSI, which is well above the typical flowmeter output pressures used in welding, giving you a wide margin of safety. Don't let a ten-cent leak ruin a hundred-dollar part—upgrade your connections with Western Enterprises brass fittings and keep your arc stable and your puddles clean.
