This fitting connects three lines at a junction point while stepping down across all three openings: a 1-1\/4 inch run inlet, a 3\/4 inch run outlet, and a 1\/2 inch branch outlet. The reducing configuration allows a single fitting to transition between multiple pipe sizes without additional reducers or couplings. Licensed plumbers and pipefitters install this type of fitting during new construction and remodel work where supply lines branch off a main distribution run at differing diameters.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is suited for residential and light commercial plumbing applications where copper distribution piping changes size at a branch point. Typical installations include domestic hot and cold water supply systems, radiant heating loops, and in-wall or under-slab rough-in work. The 1-1\/4 x 3\/4 x 1\/2 inch sizing makes it a common choice where a larger main line feeds a reduced branch to a fixture or zone valve.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing tee configuration handles three different pipe sizes in a single fitting\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch run inlet x 3\/4 inch run outlet x 1\/2 inch branch outlet\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance and long service life in water systems\u003c\/li\u003e\n  \u003cli\u003eEliminates the need for separate reducer couplings at branch transitions\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard sweat (solder) joining methods used in copper piping work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-use fitting for copper plumbing systems using 1-1\/4 inch, 3\/4 inch, and 1\/2 inch pipe sizes joined by sweat soldering.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber using standard copper sweat-soldering tools including a torch, flux, and lead-free solder meeting ASTM B32 and local plumbing code requirements. Shut off the water supply and fully drain the affected lines before cutting and fitting. Follow local IPC or UPC code requirements for solder composition on potable water systems. Do not overtighten or force-fit the tee onto pipe ends; ensure pipe is properly reamed, deburred, and cleaned before applying flux and heat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRun Inlet Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRun Outlet Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBranch Outlet Size\u003c\/strong\u003e: 1\/2 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 Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Sweat (Solder)\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: COTRED1143412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524656791858,"sku":"COTRED1143412","price":39.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adc59379ae2b91fe4e74d242c8f69c06_fa35f367-5f99-41c3-94d9-2b32f8951be2.jpg?v=1785454302","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cotred1143412-copper-reducing-tee","provider":"Voomi Supply","version":"1.0","type":"link"}
