Glass TIG Torch Nozzle for Number 9&20, Narrow Coverage

Manufacturer part: 77425A281

Direct the flow of shielding gas to your weld with these nozzles. When choosing a nozzle size, consider the thickness of the material you’re welding. In general, the thicker the material, the higher the nozzle size you should use. All nozzles require a compatible collet in order to connect to your TIG torch. Borosilicate Glass—Borosilicate glass nozzles are clear, so you can see what you’re working on even in tight corners, but they break more easily than other nozzles. These nozzles require a push-on collet body. For Narrow Gas Coverage—Nozzles for narrow gas coverage are good for welding most metals.Gas-Saving TIG Welding—Gas-saving nozzles use less gas than standard nozzles but won’t compromise the quality of your weld. These nozzles require a gas diffuser, which prevents oxidation and pitting in the weld by reducing gas turbulence and improving shielding.
