It transitions from a 1-1\/2 inch pipe to a 1-1\/4 inch pipe in a single fitting, eliminating the need for adapters or additional components. This fitting is used in potable water, hydronic heating, and general plumbing distribution systems. Licensed plumbers and pipefitters install this fitting wherever a pipe run requires a diameter reduction, keeping flow paths clean and leak-free when properly soldered.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is suited for residential and light commercial plumbing installations. Typical applications include domestic hot and cold water supply lines, recirculation loops, and hydronic heating distribution piping. The C x C end configuration requires both pipe ends to be cleaned, fluxed, and soldered per standard copper joining practices. It fits inline wherever a 1-1\/2 inch line must step down to 1-1\/4 inch without introducing a union or threaded transition.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions from 1-1\/2 inch to 1-1\/4 inch copper pipe in a single fitting\u003c\/li\u003e\n\u003cli\u003eC x C (copper sweat) ends on both sides for a fully soldered, leak-resistant joint\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance suitable for potable water systems\u003c\/li\u003e\n\u003cli\u003eCompact reducing coupling profile minimizes installation space requirements\u003c\/li\u003e\n\u003cli\u003eCompatible with standard Type K, L, and M copper tubing of the corresponding sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use reducing coupling for 1-1\/2 inch to 1-1\/4 inch copper sweat piping systems in residential and light commercial plumbing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and drain the water supply completely before cutting into any existing pipe run. Clean all pipe ends and fitting sockets with emery cloth or a fitting brush, apply appropriate flux, and solder using lead-free solder per code requirements for potable water systems. Avoid overheating the fitting during soldering, as excessive heat can damage the copper and compromise joint integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection Type\u003c\/strong\u003e: C x C (copper sweat, both ends)\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: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CORED112114\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51523886940466,"sku":"CORED112114","price":20.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2861748bfa8ae07cc2b85a3694335df7.jpg?v=1785444265","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cored112114-copper-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
