54N16 - Weldcraft 54N16 Alumina Gas Lens Nozzle #6 (3/8") - 10 Pack

Upgrade Your TIG Torch with Better Gas Coverage

If you are looking to smooth out your gas flow and get cleaner, colorful welds, switching to a gas lens setup with the Weldcraft 54N16 Nozzle is one of the best upgrades you can make. This #6 cup (3/8") is the workhorse of the TIG world—perfect for everything from mild steel brackets to stainless exhaust work. Made from tough alumina ceramic, these cups can take the heat without crumbling or cracking halfway through a job.

Why use this gas lens cup over a standard cup? It's all about the flow. When paired with a gas lens body, this nozzle pushes gas out in a straight, calm column rather than a chaotic cloud. This means you can stick your tungsten out further—sometimes up to an inch depending on conditions—to see exactly what you are doing in tight corners or deep grooves. It also helps keep your puddle clean and reduces the chance of porosity, saving you from grinding out bad welds.

These cups fit the standard 17, 18, and 26 series torches found in almost every shop. Whether you are running an air-cooled 17 or a water-cooled 20, if you have the gas lens setup, this cup fits. They come in a pack of 10, so you can keep a stash in your toolbox and never be caught without a fresh cup when you drop your torch or walk the cup a little too hard. Reliable, durable, and essential for precision work.
