12301100 - Tweco 23-37 Style MIG Nozzle, 3/8" Bore, Slip-On (2-Pack)

Reliable Performance with Tweco 23-37 Style Nozzles

Keep your MIG gun running smoothly with this 2-pack of Tweco 23-37 style nozzles. If you are welding with a Tweco No. 3 or No. 4 gun, you know that the nozzle takes the brunt of the heat and spatter. These standard nozzles feature a 3/8-inch bore, which is the go-to size for many general welding jobs, giving you tight, efficient gas coverage that helps keep your puddles clean and your arcs stable.

The best thing about the 23 Series design is the slip-on fit. No more wrestling with seized threads when you need to clean out spatter or change a contact tip. Just twist and pull, and you have access to your front-end consumables. These nozzles are built from heavy-duty copper alloy, meaning they stand up to the heat of 300 to 400 amp welding and resist spatter buildup better than cheaper alternatives. When spatter does stick, the smooth copper surface makes it easier to ream out.

Whether you are in a production shop or a home garage, having spares on hand is a must. A worn or clogged nozzle can ruin your gas coverage and lead to porosity in your welds. With this convenient 2-pack, you can swap out a beat-up nozzle instantly and get back to laying beads. These nozzles fit perfectly over your standard insulators and stay put until you are ready to take them off.
