Every TIG welder knows the frustration of trying to lay a bead in a tight corner, inside a roll cage, or around a complex exhaust manifold, only to have the long tail of the torch bump against the workpiece. That standard long back cap sticking out the back of your torch can be a real deal-breaker when space is at a premium. Enter the 57Y04 Short Back Cap—often called the "button" or "stubby" cap. This little accessory is a game-changer for anyone doing automotive fabrication, pipe welding, or maintenance repair in cramped quarters.
Designed to fit the most popular torches in the industry—the 17, 18, and 26 series—this cap replaces your standard long cap and instantly shrinks the profile of your torch. By removing that extra length, you gain the freedom to manipulate your torch angle comfortably, even when you're jammed between two pipes or working inside a box. It’s made from tough, heat-resistant material that can handle the heat of the job without melting or deforming, ensuring it lasts through your toughest projects.
Using the short back cap is simple, but remember: because it's short, your tungsten needs to be short too. You'll need to use a cut-down piece of tungsten or a "stub" to fit inside. This is actually a great way to use up those shorter pieces of tungsten that are too small for the long cap but too good to throw away. The cap comes with a fresh O-ring to ensure you get a perfect gas seal every time, keeping your welds clean and porosity-free.
Whether you are a professional pipe welder or a garage fabricator, keeping a couple of these 57Y04 caps in your kit is a no-brainer. They are an inexpensive solution to a common problem, allowing you to weld comfortably in places you couldn't reach before. Compatible with Weldcraft, Miller, Lincoln, and most generic torches, it's the versatile upgrade your torch setup needs.
