B-Size Oxygen Hose Nut, 9/16-18 RH Brass Fitting

Reliable Replacement Nut for Oxygen Hoses

Keep your oxy-fuel rig running smoothly and safely with the Western Enterprises WES7 Oxygen Hose Nut. Over time, the brass fittings on your welding hoses can take a beating. Threads get stripped, hexes get rounded off from pliers, or the metal simply fatigues. When it's time to repair a leak or build a new hose extension, you need a nut that fits perfectly and holds tight. The WES7 is the standard B-Size nut you need for almost all standard oxygen regulators and torches found in welding shops across the country.

Why the Right Nut Matters
In welding, the difference between a safe setup and a dangerous one often comes down to the fittings. This nut features Right-Hand threads, which is the universal code for "Oxygen." This prevents you from accidentally screwing an oxygen hose onto an acetylene or propane regulator. The solid brass construction isn't just for looks; it's durable, resists corrosion from the elements, and most importantly, it's non-sparking. If you drop your torch or drag the line across concrete, you want fittings that can handle the abuse without compromising safety.

Easy Installation and Maintenance
Designed with an 11/16" hex, this nut is easy to tighten with your standard wrench set—no need to hunt for specialty tools. It fits 9/16"-18 threads, commonly referred to as "B-Size" fittings. Whether you are fixing a cut line in the field or setting up a new manifold system in the shop, having a few of these nuts in your toolbox can save the day. A leaky connection wastes expensive gas and creates a fire hazard; swapping out a damaged nut is a quick, cheap fix that ensures your flame stays stable and your shop stays safe.

Applications
This nut is compatible with any standard B-Size oxygen nipple. It is rated for up to 200 PSI, covering all your typical cutting and welding pressures. Use it for repairing hoses on portable torch kits, track burners, or stationary bench setups. Don't let a stripped nut shut down your project—grab the WES7 and get back to burning.
