Western Enterprises F-31 CGA-295 to 1/4" NPT Male Brass Adapter

Reliable Adapter for Argon and Nitrogen Setups

For welders and fabricators, having the right connections is the difference between a smooth project and a frustrating day of chasing leaks. The Western Enterprises F-31 Valve Stem Adapter is a must-have fitting for anyone working with inert gas cylinders, particularly those set up for Argon, Nitrogen, or Helium mixtures. This solid brass adapter is designed to convert a CGA-295 connection into a standard 1/4-inch NPT Male thread, giving you the flexibility to hook up your regulators, hoses, or custom manifolds exactly how you need them. Whether you are building a purge line for stainless steel welding or setting up a central gas distribution system in your shop, this adapter provides the secure link you need.

Built to last, the F-31 is machined from heavy-duty brass. In a welding shop environment, equipment takes a beating—tools get dropped, parts get knocked around, and temperature fluctuate. Brass is the ideal material for this application because it is tough enough to resist physical damage but soft enough to create a tight metal-to-metal seal when tightened properly. It is also naturally spark-resistant, adding an extra layer of safety to your gas setup. With a pressure rating of 500 PSIG, this fitting is more than capable of handling the delivery pressures typically found in shop lines and manifold systems, ensuring you have a steady and safe flow of shielding gas to your welder.

One of the biggest advantages of the F-31 is its versatility. The 1/4-inch NPT Male thread is one of the most common thread sizes in the industry. This means you can screw this adapter directly into a wide range of aftermarket regulators, valves, and pipe fittings without hunting for obscure converters. If you are retrofitting an older regulator or building a custom "pigtail" hose to connect a bulk tank to your machine, this adapter bridges the gap. It simplifies your inventory; instead of keeping a drawer full of random bushings, a few of these high-quality adapters can solve multiple connection problems related to inert gas cylinders.

Safety is always priority number one when dealing with compressed gases. The CGA-295 standard is specific to inert gases, preventing you from accidentally hooking up a flammable or oxidative gas to your shielding line. The Western Enterprises F-31 respects this standard with precision machining that ensures a perfect fit with CGA-295 nuts and valves. No forcing threads, no cross-threading—just a smooth, secure connection every time. When you install the F-31, you can trust that your gas system is leak-free and safe, allowing you to focus on laying down perfect beads rather than worrying about your equipment.
