36Z40 - ESAB 36Z40 B-Size Hose Nut, 5/8"-18 RH, Brass

Secure Your Gas Lines with Confidence

When you are in the middle of a critical weld or a heavy cutting job, the last thing you need is a leaky hose connection. The ESAB 36Z40 Hose Nut is the reliable solution for replacing worn, stripped, or damaged nuts on your oxygen or inert gas lines. Designed with the standard B-Size 5/8"-18 Right Hand thread, this nut is the industry standard for connecting your hoses to regulators and torches. It is a small but vital part of your setup, ensuring that your gas flow remains consistent and your work environment remains safe from hazardous leaks.

Built for the Welding Shop

Welding gear takes a beating, and your fittings are no exception. Dragging hoses across the floor, frequent equipment changes, and the general wear and tear of shop life can take a toll on brass fittings. The ESAB 36Z40 is machined from solid brass, giving it the toughness to withstand daily abuse without cracking or cross-threading. The clean threads ensure a smooth action when you are tightening down your connections, giving you that positive feedback that the seal is tight and ready for pressure. It is the kind of quality part that gives you peace of mind every time you crack open the cylinder valve.

Universal Fit for Oxygen and Inert Gases

This nut isn't just for one specific machine; it's a universal problem solver for your B-Size connections. Because it uses Right Hand threads, it is compatible with Oxygen lines for your oxy-fuel torch, as well as Argon, Helium, and mixed gas lines for your MIG and TIG welders. Whether you are running an old-school Purox torch or a modern ESAB power source, if it uses a standard B-Size gas outlet, this nut is the correct fit. Keep a few in your toolbox or parts bin so you are never stuck waiting on a simple fitting to get back to work.

Easy Maintenance and Repair

Fixing a damaged hose end is a quick way to extend the life of your expensive welding hoses. By pairing the ESAB 36Z40 nut with a compatible nipple and a hose ferrule or clamp, you can repair a cut or damaged hose end in minutes. Don't let a crushed nut or stripped thread compromise your weld quality or safety. Swap it out with a genuine ESAB replacement and get back to laying beads with the confidence that your equipment is sealed, secure, and professional.
