12401404 - Tweco 24CT-37 MIG Nozzle, 3/8" Bore, Coarse Thread (2-Pack)

Reliable Shielding for Professional MIG Welding

Keep your MIG torch performing at its peak with the Tweco 24CT-37 Standard Nozzle. Designed for professional welders who demand consistency, this nozzle is a staple for anyone running Tweco No. 3 or No. 4 MIG guns. The nozzle plays a crucial role in directing shielding gas over the weld puddle, protecting it from atmospheric contamination that leads to porosity and weak welds. With its 3/8-inch bore, this specific model offers a slightly narrower opening than the standard 1/2-inch version, providing tighter gas coverage and better access when welding in corners or confined spaces.

Built for the Grind
Welding generates intense heat and spatter, which can quickly degrade inferior consumables. The Tweco 24CT-37 is machined from durable copper alloy, chosen for its ability to withstand thermal shock and resist spatter adhesion. This means you spend less time cleaning your nozzle and more time laying beads. The coarse thread design is a favorite among fabricators because it is less likely to seize up after a long day of welding, allowing for quick, frustration-free changeouts when it's time to replace the nozzle or clean the diffuser.

Perfect Fit and Function
Whether you are repairing heavy equipment or fabricating structural components, having the right nozzle size is essential. This 2-pack ensures you always have a backup ready to go. The nozzle fits seamlessly with standard Tweco insulators and gas diffusers, maintaining the correct tip-to-nozzle recess for stable arc characteristics. Upgrade your consumable kit with genuine Tweco parts and experience the difference in durability and performance.
