KP3360-1-B25 - Lincoln Electric 350A Extended Reach Thread-on Gas Diffuser (25-Pack)

Reach Further and Weld Better

When you are deep in a weld and trying to get the perfect angle on a tight corner, the last thing you want is your gun geometry holding you back. The Lincoln Electric KP3360-1-B25 Gas Diffuser is built with an extended reach design specifically to solve that problem. By extending the contact tip position, this diffuser gives you that extra clearance needed to see the puddle clearly and manipulate the arc in restricted spaces. It is designed for 350A thread-on guns, making it a robust choice for heavy-duty MIG applications where heat and spatter are constant factors.

We know that a loose diffuser can ruin a good day of welding. That is why the thread-on connection of the KP3360-1 is so important. Unlike slip-on parts that can loosen up as the gun heats and cools, this diffuser threads securely into place. This ensures a solid electrical connection, which means a smoother, more consistent arc and less heat buildup in the front end of your gun. A cooler running gun means your consumables last longer, and you spend less time swapping out parts and more time burning wire. The gas ports are precision-drilled to ensure your shielding gas flows smoothly, preventing porosity and keeping your welds clean.

This product comes in a pack of 25, which is perfect for busy shops. There is nothing worse than reaching for a replacement part and finding the bin empty. With this bulk pack, you can keep a handful in your toolbox or at your station, ensuring you are always ready to go. The durability of these diffusers means you won't be changing them constantly, but when you do need a fresh one, you have plenty on hand. They are built to withstand the abuse of daily fabrication work, resisting thread galling and maintaining their shape even after hours of welding at high amperages.

If you are running a Lincoln 350A setup and find yourself struggling to get into tight spots, or if you just want a reliable, high-quality diffuser that stays put, the KP3360-1-B25 is the upgrade you need. It delivers the reliability Lincoln is famous for, combined with the practical design features that professional welders demand. Upgrade your front-end consumables and experience the difference in access and arc stability.
