KP3075-1-38S-B25 - Lincoln Electric Magnum PRO Gas Nozzle, 3/8 ID, 1/4 Stick-out, Thread-on (25-Pack)

Keep Your Magnum PRO Running Smoothly

Every welder knows that the nozzle is the first line of defense for your MIG gun, taking the brunt of the heat and spatter day in and day out. The Lincoln Electric KP3075-1-38S-B25 gives you a supply of 25 high-quality gas nozzles, ensuring you aren't left scrambling for a replacement in the middle of a job. Designed specifically for the popular Magnum PRO 100L and 175L guns, these nozzles are built to fit perfectly and perform reliably. If you are running a smaller MIG machine in a garage, body shop, or light fab station, these are likely the exact replacements you need to keep your welds clean and your arc stable.

The 3/8-inch bore size on these nozzles is excellent for general-purpose welding, offering a tight, focused cone of shielding gas that saves you money on gas flow while protecting the puddle. One of the standout features is the 1/4-inch stick-out. Because the contact tip sits recessed inside the nozzle, you get better visibility of the wire as it hits the joint, which is a huge help when you are trying to follow a tricky seam. This recess also helps keep your contact tip cleaner for longer, as it isn't sticking out into the spatter zone as much as flush nozzles. Whether you are welding mild steel, stainless, or doing some flux-cored work (where a nozzle protects the threads even if gas isn't used), this geometry is versatile and user-friendly.

Forget about nozzles that rattle loose or fall off when they get hot. These feature a secure thread-on design that locks them tightly to the diffuser. This solid connection doesn't just keep the nozzle in place; it helps pull heat away from the tip, keeping your consumables cooler and lasting longer. With this 25-pack, you can swap out crusty, spatter-filled nozzles without hesitation, ensuring your gas coverage is always perfect. Clean nozzles mean less porosity and less grinding later. Stock up your tool crib or welding cart with this bulk pack and focus on laying beads rather than cleaning out clogged nozzles.
