PSTB80300236 - Parker Stubby TIG Torch Insulator Gasket

Get into Tight Spots with the Right TIG Setup

Every TIG welder knows the struggle: you need to lay a bead in a tight corner, inside a manifold, or around a roll cage, but your standard WP-17 or WP-26 torch head is just too bulky. That's where a "stubby" kit comes in handy, shrinking your torch's front end down to the size of a WP-9 or WP-20. But to make that conversion work, you need the right parts. The Parker Cup Gasket Stubby (PSTB80300236) is the essential insulator you need to complete that setup and get welding.

This isn't just a piece of plastic; it's the heat shield and seal that keeps your torch running right. When you switch to a stubby gas lens, your old insulator won't fit. This Parker gasket is designed to sit perfectly between your torch handle and the gas cup, creating a tight seal that prevents your expensive Argon from leaking out before it hits the puddle. A bad seal means sucked-in atmosphere, black tungsten, and porosity in your welds—headaches you don't need when you're in an uncomfortable position trying to finish a joint.

Why choose Parker? Parker Torchology parts are built to last. We've all had cheap white gaskets that crack after a few heat cycles or melt if you push the amperage a little too hard. This gasket is made from durable, high-heat material that stands up to the reflection of the arc, keeping your torch body protected. It fits snug, ensuring your cup screws on tight and stays there.

If you are running a stubby setup on your air-cooled 17/26 or water-cooled 18 torch, check your insulator regularly. If you see charring, cracks, or if the cup feels loose no matter how much you tighten it, it's time to swap it out. Keep a few of these Parker Stubby Cup Gaskets in your tackle box or welding cart. It’s a small part that makes a huge difference in your ability to weld comfortably and cleanly in restricted spaces.
