These pre-formed rings are used to join copper refrigerant lines and fittings during HVAC system installation and service. The Sil-Fos 15 alloy designation indicates a silver-bearing, self-fluxing composition suited for copper-to-copper joints, delivering a strong, leak-resistant bond when properly applied. HVAC technicians rely on pre-formed rings to deposit a consistent, controlled amount of alloy at the joint, reducing the risk of over- or under-brazing on refrigerant circuit connections.\u003c\/p\u003e\u003cp\u003eThese brazing rings are suited for residential and light commercial HVAC applications where 3\/8 inch copper tubing is joined at coil connections, line set fittings, or service valve assemblies. The pre-formed ring format is particularly useful in tight equipment cabinets where feeding rod filler material by hand is difficult. Licensed HVAC technicians and refrigeration mechanics are the primary installers in this application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSil-Fos 15 alloy composition — self-fluxing on copper-to-copper joints\u003c\/li\u003e\n\u003cli\u003ePre-formed ring format for consistent alloy placement at the joint\u003c\/li\u003e\n\u003cli\u003eSized for 3\/8 inch tubing connections\u003c\/li\u003e\n\u003cli\u003eProduces a high-strength, leak-resistant brazed joint in refrigerant circuits\u003c\/li\u003e\n\u003cli\u003eReduces material waste compared to cut-length rod filler\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style brazing consumable for copper-to-copper refrigerant tubing joints commonly found in residential and light commercial HVAC systems using 3\/8 inch line connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBrazing of refrigerant circuits must be performed by EPA Section 608 certified technicians following applicable mechanical and refrigeration codes. Purge the refrigerant circuit with dry nitrogen during brazing to prevent internal oxidation scaling. Ensure the system is fully recovered and depressurized before cutting or opening any refrigerant line. Allow joints to cool completely before pressurizing for leak testing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlloy Type\u003c\/strong\u003e: Sil-Fos 15 phosphor-silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Pre-formed ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTubing Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRANE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 98701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51524802969906,"sku":"98701","price":25.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/883dc0fd6449cc872e9bb4b217e52e53.webp?v=1785458042","url":"https:\/\/voomisupply.com\/products\/trane-98701-sil-fos-15-brazing-rings-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
