This nozzle features an 11 mm (7\/16 inch) orifice diameter and is a direct replacement component for use with compatible ESAB TIG torch bodies. Welding technicians and fabricators install this nozzle as part of routine torch maintenance or when upgrading consumables to restore arc quality and shielding gas coverage. Proper nozzle selection directly affects weld bead quality and tungsten contamination risk, making correct sizing critical.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for light-duty to medium-duty TIG welding applications where a Size 7 orifice is specified. It is compatible with the 20A torch as well as Torch HW17, HW18, and HW26, and Torch HW20. Typical use cases include sheet metal fabrication, pipe welding, and structural work performed in both shop and field environments. The Size 7 designation indicates the nozzle orifice measures 7\/16 inch (11 mm), which provides adequate shielding gas coverage for a wide range of base metals and joint configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 7 nozzle with 11 mm (7\/16 inch) orifice for consistent shielding gas coverage\u003c\/li\u003e\n  \u003cli\u003eDirect replacement consumable for ESAB TIG torch bodies HW17, HW18, HW26, and HW20\u003c\/li\u003e\n  \u003cli\u003eCompatible with the 20A torch configuration\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement as needed\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.01 pounds for easy handling during torch assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the ESAB 20A torch and Torch HW17, HW18, HW26, and Torch HW20.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTIG torch nozzles are installed and serviced by qualified welders or welding equipment technicians. Always disconnect the torch from the power source and allow it to cool completely before removing or installing consumables. Thread or press the nozzle onto the torch body according to the torch manufacturer's assembly instructions, ensuring a secure fit to prevent shielding gas leaks. Inspect the nozzle for cracks or spatter buildup before each use and replace when damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrifice Size\u003c\/strong\u003e: Size 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrifice Diameter\u003c\/strong\u003e: 11 mm (7\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23271700\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ESAB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0157121039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ESAB","offers":[{"title":"Default Title","offer_id":51541547942194,"sku":"0157121039","price":23.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d1a2c9f0b62f3edd14ddaa471053b38.jpg?v=1785879085","url":"https:\/\/voomisupply.com\/products\/esab-0157121039-tig-torch-nozzle-size-7-11-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
