It transitions from a 1\/2-inch end to a 1\/8-inch end, allowing plumbers and HVAC technicians to reduce line size within a system without additional adapters. The coupling uses standard copper-to-copper solder joints on both ends, making it compatible with common torch brazing and soft-solder installation methods. It is a compact, reliable fitting used in refrigeration, plumbing, and HVAC piping assemblies where a clean, leak-free reduction is required.\u003c\/p\u003e\u003cp\u003eThis reducing coupling suits residential and light commercial applications where copper tubing runs require a size transition. Typical install scenarios include domestic water supply lines, drain and vent piping, HVAC refrigerant line segments, and hydronic systems. The C x C end configuration means both connections are sweat-soldered, making it a straightforward choice for licensed plumbers and HVAC technicians working with standard copper tubing installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces from 1\/2-inch to 1\/8-inch in a single fitting, eliminating extra adapters\u003c\/li\u003e\n\u003cli\u003eC x C (sweat-solder) end connections on both sides for standard torch installation\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance and reliable joint integrity\u003c\/li\u003e\n\u003cli\u003eCompact profile suits tight spaces in plumbing and HVAC piping runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-use fitting for copper tubing systems requiring a 1\/2-inch to 1\/8-inch reduction with sweat-solder end connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and IFGC or IPC guidelines. Shut off and depressurize the water or refrigerant line before cutting and fitting. Clean and flux all mating tube ends thoroughly before soldering to ensure a leak-free joint. Do not apply heat directly to flux residue left on finished joints; clean after soldering per standard practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection Type\u003c\/strong\u003e: C x C (Sweat Solder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Coupling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CORED1218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524786127154,"sku":"CORED1218","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2861748bfa8ae07cc2b85a3694335df7_4fa41193-8a9c-4d9d-a70c-295e9a2bde58.jpg?v=1785457463","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cored1218-copper-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
