It provides a three-way branch connection with a reduced branch outlet, allowing a smaller secondary line to tap off a main run without requiring additional adapters. The fitting is manufactured from copper, which offers reliable corrosion resistance and long service life in both hot and cold water applications. Licensed plumbers and mechanical contractors install this type of fitting during new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is suited for potable water distribution, hydronic heating loops, and general mechanical piping where a 3-inch main run requires a 1-inch branch takeoff. The fitting is compatible with standard sweat soldering assembly using clean copper tube ends and appropriate flux and solder. It is commonly used where branch circuits supply fixtures, zone lines, or secondary equipment from a larger main.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance in potable water and hydronic systems\u003c\/li\u003e\n  \u003cli\u003eReducing branch outlet eliminates the need for a separate reducer fitting on the branch side\u003c\/li\u003e\n  \u003cli\u003e3-inch run by 3-inch run by 1-inch branch configuration for common main-to-branch transitions\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard sweat solder installation per IPC and IFGC-referenced plumbing practices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for copper sweat piping systems using standard Type K, Type L, or Type M copper tube in matching nominal sizes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing code and IPC guidelines. Shut off and depressurize the water system fully before cutting into any existing line. Tube ends must be cut square, deburred, and cleaned with emery cloth before applying flux and soldering. Avoid overheating the fitting during soldering, as excessive heat can damage the joint integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRun Size\u003c\/strong\u003e: 3 inches x 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBranch Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Sweat (solder)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Tee\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: COTRED331\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524670095666,"sku":"COTRED331","price":109.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cafa517ad89b08802b61b81953f3bf26.jpg?v=1785454735","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cotred331-copper-reducing-tee","provider":"Voomi Supply","version":"1.0","type":"link"}
