54N17 - Weldcraft 54N17 #5 Alumina Gas Lens Cup (10-Pack)

Enhance Your TIG Precision with Weldcraft 54N17 Gas Lens Nozzles

For welders looking to improve their weld quality and visibility, the Weldcraft 54N17 Alumina Gas Lens Nozzle is an essential upgrade for your torch. Designed to fit the popular 17, 18, and 26 series TIG torches, this #5 cup (5/16-inch) is specifically built to work with gas lens collet bodies. If you are tired of turbulence disrupting your shielding gas or struggling to see the puddle in tight corners, switching to a gas lens setup with this high-quality alumina cup is the solution.

Why Choose a Gas Lens Nozzle?
Standard TIG cups work fine for basic jobs, but they often produce turbulent gas flow that can pull in atmospheric air, leading to porosity or oxidation. The 54N17 nozzle works in tandem with a gas lens to create a smooth, laminar column of gas. This means you can extend your tungsten further out of the cup—sometimes up to an inch depending on the setup—allowing you to reach into deep V-grooves or tight pipe angles while keeping the weld pool perfectly shielded. The #5 size is particularly useful for tighter joints where a larger cup would obstruct your view or fail to fit.

Built for the Shop Environment
Made from durable alumina ceramic, these nozzles are built to withstand the intense heat of TIG welding without cracking or melting. They offer excellent impact resistance, meaning they can handle the occasional bump against the workpiece. The material also resists spatter buildup, making cleanup quick and easy so you can keep your arc on time high. Whether you are welding stainless steel, chromoly, or mild steel, these cups provide the consistency professional fabricators demand.

This pack contains 10 nozzles, ensuring you have plenty of spares on hand for long projects. Compatible with all major brands of air-cooled (17, 26) and water-cooled (18) torches using medium gas lenses, the Weldcraft 54N17 is a reliable workhorse for any serious TIG welder's kit.
