Tweco Style 21 Series MIG Nozzle (5-Pack) 21-37, 21-50, 21-62

Crafted for durability, the nozzle housing is cut and formed from copper alloy tubing, paired with a solid brass alloy insert, ensuring long-lasting reliability in tough welding conditions. A built-in silicone insulator provides critical electrical insulation from the gas diffuser. Available in 3/8, 1/2, 5/8, and 3/4 inch sizes, this nozzle supports light to medium-duty welding tasks up to 160 amperes. Compatible with Lincoln K530-5 100L Magnum, Tweco #1 100AMP MIG Gun, and 160A Spool Guns, fitting Tweco 51 Diffuser threads and 61 Series Tubes.
