It connects a 3\/8 inch OD (1\/4 inch ID) tube on one end to a 5\/16 inch OD (3\/16 inch ID) tube on the other, allowing technicians to step down tubing size within a refrigeration or plumbing line. This fitting is suited for brazed or soldered joints and is a standard component in copper tubing systems where a diameter transition is required. HVAC and refrigeration technicians as well as plumbers install this type of fitting during new construction and service work.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is used in residential and light commercial applications where copper tubing runs must transition between two different outside diameters. Common installation scenarios include refrigerant line modifications, ACR (air conditioning and refrigeration) tubing work, and small-diameter domestic plumbing runs. The C x C end configuration requires a sweat or braze connection on both ends, making it a straightforward choice when working in all-copper systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces from 3\/8 inch OD (1\/4 inch ID) to 5\/16 inch OD (3\/16 inch ID)\u003c\/li\u003e\n\u003cli\u003eC x C configuration accepts sweat or braze connections on both ends\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance and reliable thermal conductivity\u003c\/li\u003e\n\u003cli\u003eCompatible with standard ACR and plumbing copper tubing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for copper tubing systems requiring a reduction from 3\/8 inch OD to 5\/16 inch OD in C x C sweat applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is installed by licensed HVAC technicians or plumbers using standard sweat-soldering or silver-brazing procedures. Shut off and recover any refrigerant or depressurize the water system before cutting into an existing line. Follow applicable codes including IFGC, IPC, and local mechanical codes for joint preparation, flux use, and alloy selection. Do not apply heat directly to the fitting body longer than necessary to avoid oxidation of the copper.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End OD\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End ID\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End OD\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End ID\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Sweat\/Braze)\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: 13112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAKOTA SOURCING","offers":[{"title":"Default Title","offer_id":51672374673714,"sku":"13112","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6228253634db8_9868bcbe-b3fc-419e-8632-066371ce8912.jpg?v=1787966669","url":"https:\/\/voomisupply.com\/products\/dakota-sourcing-13112-copper-reducing-coupling-c-x-c","provider":"Voomi Supply","version":"1.0","type":"link"}
