12621037 - Tweco 26-62-F MIG Nozzle, 5/8" Bore, Flush Tip (1262-1037)

Reliable Flush Nozzle for Spray Master & Professional Guns

Keep your heavy-duty MIG gun running smooth with the Tweco 26-62-F Nozzle (Part #1262-1037). If you are running a Tweco Spray Master 450 or one of the big Professional series guns (No. 5 or No. 6), this is the workhorse nozzle you need in your kit. Built tough from solid copper alloy, it stands up to the intense heat of high-amperage welding and resists spatter buildup, so you spend less time cleaning your nozzle and more time laying beads.

The 5/8-inch bore is the "goldilocks" size for most industrial jobs—wide enough to give you excellent gas coverage on thicker materials, but not so bulky that it blocks your view of the puddle. This model features a Flush tip relationship, which places your contact tip right at the edge of the nozzle opening. Many welders prefer this setup because it makes it easier to judge your stick-out distance and get closer to the work without snagging, all while keeping the tip cool and shielded. It's a great all-arounder for everything from shop fabrication to field repairs.

Installation is straightforward, fitting securely onto your gun's front end parts. When your gas shielding is consistent, your welds are cleaner, and you have less porosity to grind out later. Don't let a worn-out nozzle compromise your weld quality; swap in a fresh Tweco 26-62-F and get back to welding with confidence. This package contains one genuine Tweco nozzle ready for action.
