54N14 - Alumina Gas Lens Nozzle #8 (1/2 Inch) for 17/18/26 Series TIG Torches

Get Better Gas Coverage with the #8 Gas Lens Cup

If you are looking to step up your TIG welding game, switching to a gas lens setup with the Generic 54N14 #8 Alumina Cup is one of the easiest upgrades you can make. This nozzle is designed to fit the popular 17, 18, and 26 series torches—the workhorses of the welding industry. Whether you are running an air-cooled WP-17 in your garage or a water-cooled WP-18 in a production shop, this cup helps you get the most out of your gas lens system.

Why use this #8 cup? The 1/2-inch opening provides a wide blanket of shielding gas that protects your weld puddle from the atmosphere. When paired with a gas lens, this cup creates a smooth, laminar flow of gas that is far less turbulent than what you get with standard nozzles. This means you can extend your tungsten electrode further out—sometimes up to an inch—without losing gas coverage. This is a game-changer when you need to see around a corner or reach into a tight fillet weld without dipping your tungsten.

Durability is key in any shop, and these nozzles are made from tough alumina ceramic. They handle the heat of high-amperage welding (up to 350 amps) without cracking or melting, and they resist spatter buildup so you don't have to constantly clean them. The 54N14 is the standard "medium" size, making it a versatile choice for everything from mild steel roll cages to stainless steel exhaust headers. Stop fighting turbulence and porosity; equip your torch with a 54N14 gas lens nozzle and see the difference in your bead appearance.

Practical Application

This cup is ideal for walking the cup on pipe or freehand welding on plate. Because it allows for a longer stick-out, you get better visibility of the arc and the puddle, which leads to more precise dips and a more consistent stack of dimes. It's a must-have for any welder's kit.
