KP23-50-B25 - Lincoln Electric KP23-50 Fixed Recess Gas Nozzle, 1/2-in ID (25-Pack)

Keep Your Magnum Gun Running Smoothly

Every welder knows that the gas nozzle is the front line of the battle against spatter and heat. If you are running a Lincoln Magnum 250LX, 300, or 400 series MIG gun, the KP23-50 is the standard nozzle you likely reach for every day. This 25-pack (KP23-50-B25) is the smart way to buy, ensuring you aren't paying a premium for single nozzles or running out right in the middle of a big project. Having a fresh box on the shelf means your team can swap out beat-up nozzles instantly and keep the arcs lit.

This specific nozzle features a 1/2-inch bore, which is the "Goldilocks" size for most MIG applications—not too wide, not too narrow. It gives you excellent gas coverage for standard joints while still being compact enough to see your puddle clearly. The "Fixed Recess" feature is a huge time-saver and quality booster. Instead of fiddling with a slip-on nozzle to guess the right tip depth, this nozzle seats in the exact same spot every time. This means your contact tip stays recessed where it belongs, protecting it from shorting out against the work and ensuring your gas shield is fully established before the arc strikes.

Durability is key when you are pushing 300 or 400 amps. These nozzles are built to take the heat. They work perfectly with wire sizes ranging from thin .025" all the way up to 5/64", covering almost everything you'd throw at a Magnum gun. Whether you are welding mild steel, stainless, or doing general repairs, a clean nozzle is the secret to a porosity-free weld. Spatter buildup inside the nozzle disrupts your gas flow, leading to bad welds and grinding time. With this bulk pack, you can afford to replace them when they get too crusty, or rotate them out for cleaning without stopping production.

Don't let a clogged or battered nozzle ruin your bead. The Lincoln KP23-50 is the OEM standard for a reason—it fits right, it lasts, and it delivers the gas coverage you need. Grab the 25-pack and secure your consumables inventory for the long haul.
