12301102 - Tweco 23-37F Standard Nozzle 3/8" Flush (2-Pack)

Tweco 23-37F Standard MIG Nozzle (2-Pack)

The Tweco 23-37F (Stock No. 1230-1102) is a standard performance nozzle designed for professional MIG welding applications. Engineered to fit the industry-standard Tweco #2, #3, and #4 MIG guns, this nozzle is a critical component for maintaining efficient gas shielding and weld quality. The '23 Series' designation indicates its compatibility with the widely used slip-on insulator system, making it a versatile choice for fabrication shops and industrial environments.

This specific model features a 3/8-inch (9.5mm) bore, which provides a focused gas column suitable for standard wire diameters and joint configurations. The Flush Tip ('F') design means the contact tip sits flush with the end of the nozzle. This geometry is preferred by many operators for its balance between gas coverage and visibility of the weld puddle, particularly in short-circuit transfer modes. The flush design also helps prevent bridging spatter from instantly clogging the orifice.

Constructed from high-quality copper alloy, the 23-37F is built to resist the intense heat of the welding arc and minimize spatter adhesion. The slip-on connection ensures that changeovers are fast and tool-free, reducing downtime during consumable replacement. This package contains two (2) nozzles, ensuring you have a backup ready when needed.
