12301302 - Tweco 23T-37F MIG Nozzle, 3/8" Tapered, Flush Tip, Thread-On (OEM)

See the Puddle Better with the Tweco 23T-37F Tapered Nozzle

If you are tired of struggling to see your arc when welding in tight corners or deep fillets, the Tweco 23T-37F tapered nozzle is the upgrade your MIG gun needs. This isn't just a standard gas cup; it's designed with a 3/8-inch bore and a tapered nose that significantly reduces the bulk at the front of your gun. This profile lets you get closer to the joint and gives you a clear line of sight to the weld puddle, which is essential for controlling your bead profile and ensuring proper fusion in difficult positions.

The 23T-37F features a "Flush" tip relationship. This means your contact tip sits right at the edge of the nozzle opening. Many welders prefer this setup for short-circuit MIG welding because it allows for a manageable stick-out while keeping the gas shielding close to the arc. It strikes the perfect balance between the recessed tips used for spray transfer and the protruding tips used for deep access, making it a versatile daily driver for most fabrication jobs.

Durability is key when you are burning wire all day. This nozzle uses a heavy-duty thread-on connection that locks onto your diffuser. Unlike slip-on nozzles that can get loose and wobble over time, this one stays put, ensuring your gas flow is always centered around the wire. The built-in G7 silicone insulator is tough as nails, resisting the high heat of the arc and preventing the nozzle from shorting out against the workpiece. Plus, the copper construction resists spatter buildup, making it easier to clean and keep in service longer. Whether you are running a Tweco Classic #2 or a Spray Master, this OEM nozzle restores your gun's performance to factory standards.
