KP2721-2 - Lincoln K231 Torch 45-Degree Curved Nozzle Extension

Get the Reach You Need with the KP2721-2

Every welder knows the frustration of trying to lay a perfect bead in a spot that your torch just doesn't want to fit into. When you are running a Submerged Arc setup like the Lincoln K231, that frustration can be compounded by the bulk of the equipment and the need to manage your flux pile. That is exactly why the Lincoln Electric KP2721-2 Nozzle Extension exists. It takes the proven performance of your K231 gun and adds a 45-degree curve to the business end, giving you the ability to reach around obstacles and down into deep joints without fighting your equipment.

Think about those tight fillet welds or deep V-grooves where a straight nozzle forces you to tilt the gun at an awkward angle, potentially messing up your flux coverage or causing wire feed issues. With the KP2721-2, you can keep your gun in a comfortable, stable position while the nozzle does the reaching for you. The 45-degree bend is designed to feed wire smoothly, so you don't have to worry about drag or bird-nesting inside the extension. It’s built with the same rugged quality you expect from Lincoln Electric, meaning it stands up to the heat and the daily grind of heavy fabrication work.

Swapping it out is straightforward, so you aren't losing valuable arc time wrestling with parts. Whether you are building ship hulls, heavy girders, or pressure vessels, having this extension in your toolbox means you are ready for the tricky joints that slow everyone else down. It’s not just an accessory; it’s a problem solver. When the prints call for a weld in a hard-to-reach corner, don't improvise—equip your K231 with the right extension and keep the arc burning smoothly.

Using genuine Lincoln parts also means you are protecting your investment. Cheap knock-offs often get the geometry wrong or use inferior copper alloys that overheat and wear out prematurely. The KP2721-2 is designed to last, ensuring that your focus stays on the puddle (or the flux line), not on equipment maintenance. Upgrade your sub-arc game and tackle complex geometries with confidence.
