The back cap threads onto the rear of the torch body to seal the collet body assembly and secure the tungsten electrode in place during welding. At 1.875 inches in length, this is a short-style cap suited for tight-access work where a standard or long cap would interfere with the weld area. It weighs 0.02 pounds and is sold individually. TIG welders and maintenance shops stock these caps as routine consumable replacements to keep torches operating correctly.\u003c\/p\u003e\u003cp\u003eThis back cap is compatible with torch series 9 and 20, which are among the most widely used air-cooled TIG torch configurations in light industrial and fabrication environments. These torches appear in pipe welding, sheet metal work, maintenance repair, and general fabrication shops. The short cap length makes it practical for welding in corners or confined joints where a long cap would be obstructed. It is a direct drop-in replacement requiring no modification to the torch body.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eShort-style cap length of 1.875 inches for restricted-access welding positions\u003c\/li\u003e\n\u003cli\u003eCompatible with Series 9 and Series 20 TIG torches\u003c\/li\u003e\n\u003cli\u003eThreads onto torch body to seal and retain the tungsten electrode\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.02 pounds — minimal added mass to the torch assembly\u003c\/li\u003e\n\u003cli\u003eSold as a single piece for targeted replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Series 9 and Series 20 TIG welding torches as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBack cap replacement is performed by a qualified welder or torch technician. Disconnect the torch from the power source and allow it to cool completely before disassembling the torch body. Thread the cap on by hand until snug — over-tightening can damage the threads on the torch body. Verify the tungsten is seated correctly and the collet body is properly installed before returning the torch to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Back Cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Torch Series\u003c\/strong\u003e: 9, 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 315090010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51727102116146,"sku":"315090010","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f57a9f95e76641d17dfea9a8dfbcddf0.jpg?v=1788673367","url":"https:\/\/voomisupply.com\/products\/pro-source-315090010-tig-torch-back-cap-1-875-in","provider":"Voomi Supply","version":"1.0","type":"link"}
