406488 - 406488 5/32" (4.0mm) TIG Collet Body 5-Pack for 17/18/26 Torches

Reliable 406488 Replacements for Your TIG Rig

Every TIG welder knows that the front-end consumables of a torch are the heartbeat of the operation. If your collet body is warped, dirty, or stripped, your arc is going to wander, and your gas coverage will suffer. This 5-pack of Generic 406488 Collet Bodies is the perfect restock solution for welders running 5/32-inch (4.0mm) tungsten. Designed to fit the industry-standard 17, 18, and 26 series torches, these parts are the workhorses of the TIG world, compatible with everything from your shop's old Miller Syncrowave torch to a brand new CK Worldwide setup.

When you are welding thick aluminum or heavy plate steel, you need the current carrying capacity of a 5/32" electrode. That means you need a collet body that can handle the heat. These copper bodies are built to take the thermal punishment of high-amperage welding without melting down or seizing up in the torch head. They provide the solid electrical connection needed to transfer power from the cable to the tungsten, ensuring smooth starts and a stable arc. Plus, the threads are machined cleanly to accept your standard ceramic cups (10N series) without binding or cross-threading.

Why buy a 5-pack? Because dropping a hot collet body on a concrete floor usually ruins the threads, and thermal cycling eventually takes its toll. Running a damaged collet body is a recipe for frustration—it can cause your collet to twist, snap, or fail to grip the tungsten properly. With this pack in your toolbox, you can swap out worn components instantly and get back under the hood. These are standard collet bodies (not gas lenses), making them the economical choice for general-purpose welding where specialized gas coverage isn't required.

These parts fit the "Big 3" of TIG torches: the air-cooled WP-17 and WP-26, and the water-cooled WP-18. They also fit compatible models like the WP-150, WP-210, and various 300-amp torches. Whether you are in a production environment or a home garage, keeping your torch consumables fresh is the cheapest way to improve your weld quality. Stop fighting with worn-out parts and grab a pack of these 406488 collet bodies to keep your arc crisp and your puddles clean.
