54N25 - ESAB 54N25 TIG Torch Insulator Gasket

Fix Your Torch and Get Back to Welding

Is your TIG torch acting up? If you are experiencing gas leaks around the cup or noticing that your arc is wandering unexpectedly, it might be time to check your insulator. The ESAB 54N25 Gasket is the standard replacement insulator for the popular 17, 18, and 26 series TIG torches. Over time, the intense heat from welding can cause your old gasket to crack, burn, or warp. When that happens, you lose shielding gas coverage and risk damaging your torch threads or even shocking yourself. This simple, affordable part is the fix you need to restore your torch to peak performance.

Installing the 54N25 is quick and easy. It fits snugly between the torch handle and the cup, creating a tight seal that keeps your shielding gas flowing exactly where it needs to go—over the weld puddle. Made from durable, heat-resistant material, this gasket stands up to the daily abuse of the shop floor. Whether you are running a water-cooled WP-18 or an air-cooled WP-17 or WP-26, this part is designed to fit perfectly. Don't let a $5 part ruin a critical weld or waste your expensive argon.

This gasket is compatible with most standard setups and is often used when configuring your torch with specific gas lenses or standard collet bodies. It's always a good idea to keep a few of these in your toolbox. When you're in the middle of a job, the last thing you want is downtime caused by a burnt-out insulator. Trust ESAB quality to keep your equipment running smoothly so you can focus on laying down perfect beads.
