3389 - Western Enterprises 3389 Brass Adapter - 1/4" NPT Male x 9/16"-18 RH Male

Reliable Oxygen Adapter for Your Rig

When you are setting up your torch or fixing a regulator, having the right fittings in your toolbox can save the day. The Western Enterprises 3389 is a must-have brass adapter for any welder dealing with oxygen or inert gas lines. This little lifesaver converts a standard 1/4-inch NPT hole into a male B-Size connection, allowing you to hook up your standard green oxygen hoses to equipment that wasn't originally designed for them, or to replace damaged outlet fittings on your gear.

We know that in the shop, durability counts. That is why this adapter is made from heavy-duty brass that won't strip out easily or crack under pressure. It features the standard Right-Hand threads you expect for oxygen service, ensuring you don't accidentally mix it up with your acetylene lines. It is perfect for adapting flowmeters, hard-piping systems, or custom manifold setups to your standard welding hoses.

Don't let a mismatched thread stop your project. With the Western 3389, you get a tight, secure seal that keeps your gas flowing where it needs to go. It is simple, effective, and built to industry standards. Whether you are running a MIG setup with Argon or an Oxy-Fuel cutting torch, this adapter ensures your connections are safe and professional. Keep a couple in your parts bin so you are never stuck looking for a way to connect your gas supply.
