This fitting is used by licensed plumbers to reduce pipe size within a run without the need for additional adapters. The Ftg x C configuration means one end slips over a copper tube like a fitting and the other end accepts a standard copper tube for soldering, making it a direct inline reducer.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and commercial plumbing systems where copper supply lines require a step-down in diameter. Typical installations include main-to-branch transitions in domestic water distribution, hydronic heating piping, and similar pressure-rated copper systems. The 4-inch to 2-inch size reduction makes it appropriate for larger-diameter main lines feeding smaller branch runs, a common configuration in multi-unit residential and light commercial construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 4 inches (Ftg end) to 2 inches (C end) in a single fitting\u003c\/li\u003e\n  \u003cli\u003eFtg x C configuration allows direct inline size reduction without additional adapters\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance and compatibility with potable water systems\u003c\/li\u003e\n  \u003cli\u003eSweat-solder connection on the C end follows standard copper joining practice\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for copper piping systems requiring a 4-inch to 2-inch reducing connection with a Ftg x C end configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber using standard copper soldering tools including a torch, flux, and lead-free solder in compliance with applicable plumbing codes such as the IPC. Shut off and drain the water supply completely before cutting into any existing line. Clean and flux all mating surfaces thoroughly before applying heat to ensure a leak-free joint. Do not apply flux inside the fitting bore until ready to solder, as premature oxidation can compromise the joint.\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\u003eInlet Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Ftg x C\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: COREDFTGC42\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524330684722,"sku":"COREDFTGC42","price":108.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0467d73255d728978ea9b67287db8e50.jpg?v=1785446189","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-coredftgc42-copper-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
