186W58 - ESAB Purox C-65 & C-59 Replacement Coupling Nut

Keep Your Purox Torch Running Strong

Don't let a stripped or worn-out nut sideline your trusty cutting torch. The ESAB 186W58 Nut is the authentic replacement part you need to restore your Purox C-65 or C-59 cutting attachment to full working order. For decades, the Purox C-series has been a favorite among welders for its reliability and performance. However, even the toughest tools need maintenance. The coupling nut is one of the most frequently handled parts of the torch assembly, often subjected to wrenching, heat, and impact. If your current nut is showing signs of wear, cross-threading, or rounding, it's time to swap it out for a brand-new OEM replacement.

Safety is the number one priority in any welding shop. A loose cutting attachment isn't just annoying—it's dangerous. It can lead to flashbacks, gas leaks, or the attachment coming loose during a cut. The ESAB 186W58 is designed to provide a rock-solid connection between your cutting attachment and the torch handle. Made from durable brass, it withstands the rigors of daily shop use and resists seizing, making it easier to swap attachments when you need to switch from cutting to heating or welding.

Why risk your equipment with ill-fitting aftermarket parts? This nut is manufactured by ESAB to the exact prints of the original Purox design. It threads on smoothly and tightens down securely, giving you the confidence that your equipment is safe and ready to perform. Whether you are refurbishing an old torch found in the back of the shop or maintaining your daily driver, this small part makes a big difference. Keep a spare in your toolbox so you never have to stop work due to a damaged thread.
