74S76 - Brass Adapter 1/4 NPT Male to 5/8-18 Female Inert Gas

Connect Your Argon Gear with Confidence

Struggling to get your gas lines hooked up because the threads don't match? The Western Enterprises 74S-76 Brass Adapter is the problem solver you need in your toolbox. This handy fitting converts a standard 1/4" NPT female port into a 5/8"-18 female connection, which is the standard "B-Size" fitting for inert gases like Argon, Helium, and Nitrogen.

If you are building a custom gas manifold, modifying a regulator, or setting up a new TIG welder, you often run into mismatched threads. This adapter bridges the gap between common pipe threads (NPT) and welding-specific gas threads. Made from heavy-duty brass, it stands up to the wear and tear of the shop and resists rust and oxidation. It's a simple, rugged part that does exactly what it's supposed to do—keep your gas flowing without leaks.

Key Applications:

• Adapting flowmeters to manifolds.
• Connecting inert gas hoses to custom equipment.
• Retrofitting regulators with different outlet ports.

Don't rely on sketchy, makeshift connections. Use the proper brass adapter to ensure your shielding gas gets to the weld puddle where it belongs. This fitting is rated for standard inert gas service and is compatible with standard US welding equipment.
