KP4523-1-75S-B25 - Lincoln KP4523-1-75S-B25 Magnum PRO Water-Cooled Nozzle 3/4-inch ID (25-Pack)

Reliable Performance for Professional Welders

Keep your shop running smoothly with the Lincoln Electric Magnum PRO Water-Cooled Nozzle, available in a cost-effective bulk pack of 25. When you are pushing your water-cooled MIG gun to the limit, you need consumables that can take the heat. The KP4523-1-75S-B25 is built to withstand the intense thermal stress of high-amperage welding, ensuring that you spend more time welding and less time changing out burned-up parts. These nozzles are a direct replacement for Magnum PRO water-cooled systems, offering the perfect fit and reliable conductivity you expect from genuine Lincoln Electric parts.

The 3/4-inch inner diameter is a game-changer for welders working on heavy structural steel or heavy equipment manufacturing. This wide bore delivers a massive column of shielding gas to the weld zone, which is critical for keeping your welds clean and passing X-ray quality inspections. Whether you are using CO2 or an Argon blend, the generous flow capacity of this nozzle helps prevent porosity caused by drafts or gun angle changes. It provides the forgiveness and coverage needed for laying down heavy beads in demanding environments.

Visibility is key to a good weld, and the 1/8-inch stickout design of this nozzle puts you in control. Because the contact tip extends slightly past the nozzle, you get a better view of the wire entering the puddle. This is especially helpful when welding in corners or tight spots where a standard flush nozzle might block your line of sight. It allows you to get the arc exactly where it needs to be without sacrificing gas coverage. The stickout design also helps keep the nozzle face cleaner for longer, as it sits slightly further back from the immediate spatter zone of the arc.

Buying in bulk is the smart choice for busy fabrication shops. This 25-pack ensures your tool crib is always stocked, eliminating the panic of running out of nozzles in the middle of a rush job. The "B25" bulk packaging offers better value per unit and reduces the hassle of frequent reordering. Equip your team with the best tools for the job—choose Lincoln Electric Magnum PRO nozzles for durability, consistency, and superior weld quality.
