23-37 - Tweco Style 23-37 Insulated MIG Nozzle, 3/8 Inch Bore

Premium Performance Tweco-Style 23-37 Insulated Nozzle

Upgrade your MIG torch setup with the 23-37 Tweco-Style Insulated Nozzle, a robust consumable built for welders who demand consistency and value. Whether you are running a Tweco Classic No. 2 in a body shop or a Lincoln Magnum on a fabrication line, this nozzle delivers the durability required for sustained welding arcs. The 3/8-inch bore is perfectly sized for light-to-medium amperage applications, concentrating shielding gas around the weld pool to prevent porosity and oxidation.

One of the standout features of this nozzle is its one-piece construction with a built-in insulator. This design not only speeds up consumable changes but also ensures a concentric fit every time, reducing turbulence in the gas flow. The nozzle creates a 1/8-inch tip recess, which is the sweet spot for many welders—protecting the contact tip from excessive spatter accumulation while keeping the stick-out manageable. Compatible with standard 52FN and 54A gas diffusers, this nozzle is an essential part of your welding inventory, ensuring your gun is ready for carbon steel, stainless, or flux-cored applications.

• Broad Compatibility: Fits Tweco #2, #3, #4 and Lincoln Magnum guns.
• Efficient Design: 3/8" bore optimizes gas usage for standard wire sizes.
• Easy Installation: Threaded base locks firmly onto the diffuser for a rattle-free fit.
