This small but essential sealing component maintains a proper gas-tight fit between the back cap and torch body, preventing shielding gas leaks that can compromise weld quality. It is used with the 41V24 Long Back Cap, 41V33 Short Back Cap, and 41V35 Medium Back Cap. Fabricators, pipe welders, and TIG welding technicians performing routine torch maintenance or back cap replacement will reach for this part to restore proper torch performance quickly and reliably.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is compatible with Series 9 and Series 20 TIG torches, which are widely used in light-duty to medium-duty TIG welding applications across fabrication shops, maintenance facilities, and job sites. It serves as a direct replacement during back cap service intervals or whenever visible wear, cracking, or gas leakage is detected at the back cap connection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement O-ring for 41V24, 41V33, and 41V35 back caps\u003c\/li\u003e\n  \u003cli\u003eSeals the back cap-to-torch body interface to prevent shielding gas leaks\u003c\/li\u003e\n  \u003cli\u003eCompatible with Series 9 and Series 20 TIG torches\u003c\/li\u003e\n  \u003cli\u003eManufactured in the United States\u003c\/li\u003e\n  \u003cli\u003eLow-cost consumable that restores torch gas integrity without full torch replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the 41V24 Long Back Cap, 41V33 Short Back Cap, and 41V35 Medium Back Cap on Series 9 and Series 20 TIG torches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified welding technician or maintenance professional. Before servicing the torch, disconnect the torch from the power source and shut off shielding gas supply at the regulator. Remove the existing back cap, extract the worn O-ring, seat the new 900-98w77 O-ring properly in the groove, and reinstall the back cap. Inspect for gas leaks after reassembly before returning the torch to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: O-Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed With\u003c\/strong\u003e: 41V24 Long Back Cap, 41V33 Short Back Cap, 41V35 Medium Back Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Torches\u003c\/strong\u003e: Series 9, Series 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: US\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: BEST WELDS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 900-98w77\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BEST WELDS","offers":[{"title":"Default Title","offer_id":51524707221810,"sku":"900-98W77","price":15.09,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/best-welds-900-98w77-o-ring-tig-torch-back-caps","provider":"Voomi Supply","version":"1.0","type":"link"}
