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

Reliable Connection for Your Welding Setup

When setting up your MIG or TIG welder, the last thing you want is to be stalled by a mismatched connection. The Western Enterprises AW-15A Inert Arc Adaptor is the problem-solver every welder should have in their toolbox. Designed to bridge the gap between different thread types, this handy brass fitting converts a 1/4-inch NPT Male port into a standard B-Size 5/8-inch-18 Right Hand Female connection. This allows you to easily connect your standard inert gas hose—typically used for Argon or Argon/CO2 mixes—to regulators, flowmeters, or machine inlets that use pipe threads.

Built for the Shop Environment

Welding shops can be tough on equipment, which is why this adaptor is made from solid brass. It stands up to daily wear and tear, resists corrosion, and ensures a tight, leak-free seal every time. A leaking gas connection isn't just a safety hazard; it wastes expensive shielding gas and can lead to porosity in your welds. With the AW-15A, you can trust that your shielding gas delivery system is secure, allowing you to focus on laying down perfect beads.

Easy Installation and Compatibility

Installing the AW-15A is straightforward. The adaptor features a 3/4-inch hex shape, giving you plenty of grip for your wrench to tighten it down securely. Because it uses the industry-standard B-Size thread for the female end, it is compatible with the vast majority of inert gas hoses found in North America. Whether you are hooking up a new TIG torch, replacing a damaged regulator fitting, or customizing a gas manifold for a purge setup, this adaptor provides the compatibility you need.

Safety First

This fitting is specifically designed for inert gases like Argon, Helium, and Nitrogen. The Right-Hand thread ensures you won't accidentally connect it to a fuel gas line, keeping your setup safe and compliant. Rated for up to 200 PSI, it easily handles the delivery pressures used in standard welding operations. Don't let a missing fitting hold up your project; keep a Western Enterprises AW-15A on hand for reliable, professional gas connections.
