It transitions from a 7\/8-inch OD (3\/4-inch ID) female socket to a 5\/8-inch OD (1\/2-inch ID) female socket, allowing a plumber or HVAC technician to step down copper line size within a refrigerant or potable water system. Copper construction provides corrosion resistance and reliable pressure integrity at brazed or soldered joints. This fitting is a standard trade component found in both mechanical and plumbing rough-in work.\u003c\/p\u003e\u003cp\u003eThe 13119 reducing coupling is suited for residential and light commercial applications where a copper line set or water supply run changes diameter. Typical install scenarios include HVAC refrigerant piping, domestic hot and cold water distribution, and hydronic heating loops where a tube-size reduction is required at a branch or equipment connection point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces from 7\/8-inch OD to 5\/8-inch OD in a single sweat fitting\u003c\/li\u003e\n\u003cli\u003eCxC (cup by cup) end configuration accepts standard copper tubing for soldering or brazing\u003c\/li\u003e\n\u003cli\u003eCopper construction resists corrosion in water and refrigerant service\u003c\/li\u003e\n\u003cli\u003eCompact coupling profile minimizes space requirements in tight chases and equipment compartments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sweat fitting compatible with standard 3\/4-inch and 1\/2-inch nominal copper tubing per ASTM B88 Type L and Type K specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or HVAC technicians using standard sweat-soldering or brazing procedures. Shut off and depressurize the water or refrigerant system and allow all lines to cool completely before cutting and fitting. Clean and flux all mating surfaces per the fitting manufacturer and applicable IPC or IFGC guidelines before applying heat. Do not overheat the fitting, as excessive heat can damage flux and compromise joint integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End OD\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End ID\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End OD\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End ID\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: CxC Sweat (Cup x Cup)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DAKOTA SOURCING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAKOTA SOURCING","offers":[{"title":"Default Title","offer_id":51669526479154,"sku":"13119","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6228253634db8_d82d758b-4b98-4672-a689-d88b538e8603.jpg?v=1787958287","url":"https:\/\/voomisupply.com\/products\/dakota-sourcing-13119-copper-reducing-coupling-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
