OVERVIEW

Protect Your Oxy-Fuel Rig

Every welder knows that keeping your gear clean and damage-free is the key to consistent performance. The Western Enterprises 86W41 Plug & Chain is a small but mighty accessory for your oxy-fuel setup. Designed to fit standard B-Size fuel connections, this brass plug is essential for capping off unused ports on your regulator, manifold, or Y-connector. Because it features Left-Hand (LH) threads, it is specifically coded for your fuel gas lines (Acetylene, Propane, etc.), ensuring you never mix up your safety caps with your oxygen gear.

Keep Dirt and Debris Out

Dust, grit, and shop grime are the enemies of gas equipment. If dirt gets into your hose connections or regulator outlets, it can cause leaks, clog your torch valves, or even create dangerous blockages. By screwing in the 86W41 plug whenever a port is disconnected, you create a solid brass barrier against contamination. It also protects the precision threads on your equipment from getting banged up or stripped during transport or storage. If you travel with your rig or have a manifold system in your shop, these plugs are mandatory for keeping your system sealed and safe.

Never Lose Your Plug Again

We've all been there—you take off a dust cap, set it down, and five minutes later it's vanished into the shop floor abyss. The 86W41 solves this problem with a sturdy retaining chain. You can attach the ring to your regulator body or piping, so the plug hangs right there when you're welding and is ready to screw back in the moment you're done. It’s a simple, hassle-free solution that saves you the frustration of lost parts.

Built for the Shop

Made from solid brass, this plug is tough enough to handle the daily abuse of a welding environment. It won't rust, and it stands up to the knocks and drops of shop life. Whether you are running a large fabrication shop with multiple stations or a mobile repair truck, having a few of these plugs on hand ensures your fuel gas lines are always secure, leak-free, and ready for action.
