OVERVIEW

Get Into Tight Spots with the #5 Long Gas Lens Cup

Struggling to get your torch into a tight corner without losing gas coverage? The 54N5L #5 Long Alumina Cup is the solution for your 17, 18, or 26 series torch. This isn't your standard stubby cup—it's an extended 3-inch nozzle designed specifically for Large Gas Lens setups. It gives you the reach you need to weld inside pipes, manifolds, and roll cages where standard cups just won't fit.

Because it mounts to a large gas lens collet body, you get the best of both worlds: the ability to extend your tungsten further (stick-out) and the physical reach of the long ceramic body. The #5 (5/16") bore keeps your shielding gas focused right where the puddle is, minimizing waste while ensuring your weld stays bright and clean. Whether you are welding stainless exhaust headers or intricate aluminum brackets, this cup helps you see the puddle and control the arc in hard-to-reach places.

Made from impact-resistant alumina ceramic, this nozzle stands up to the heat of daily welding. It's a must-have addition to your TIG kit for those days when a standard cup leaves you stuck on the outside looking in. Upgrade your reach and keep your welds clean with the 54N5L.

FAQ

It fits 17, 18, and 26 series torches (including WP-17, WP-18, WP-26, CS300, CS410) when equipped with a Large Diameter Gas Lens collet body.

Yes, this nozzle requires a Large Diameter Gas Lens collet body (e.g., 45V64 for 3/32" tungsten, 45V116 for 1/16"). It will not fit standard collet bodies or standard gas lenses.

A #5 cup has an orifice diameter of 5/16 of an inch, or approximately 8.0 millimeters.

The 'L' designation typically indicates a length of approximately 3 inches (76mm), significantly longer than the standard 54N series cups.

The gas lens provides laminar flow, allowing for a longer tungsten stick-out. Combined with the long cup body, this setup is perfect for reaching into deep recesses while maintaining excellent shielding.

Yes, the alumina ceramic material is suitable for both AC and DC welding processes.

54N15 is the standard length #5 cup for large gas lenses. 54N5L (or 54N15L) is the extended length version of the same cup size.
