It transitions from a 2.5-inch socket on one end to a 2-inch socket on the other, allowing a plumber to step down copper pipe sizes within a water supply or hydronic system. The C x C ends accept standard copper tubing for a clean, torch-soldered joint. This fitting is a standard component in residential and light commercial plumbing rough-in and repipe work.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for water distribution lines, hydronic heating loops, and similar closed-loop or potable water systems where a pipe size reduction is required mid-run. It is typically installed by licensed plumbers during new construction, renovation, or repair work where supply line sizing changes between runs. Both ends use the cup-and-solder (C x C) connection method, requiring standard copper fittings preparation and lead-free solder per applicable code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 2.5-inch to 2-inch copper pipe in a single fitting\u003c\/li\u003e\n  \u003cli\u003eC x C ends for sweat-solder connection on both sides\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance in potable water and hydronic applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard Type L and Type M copper tubing\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 piping systems requiring a 2.5-inch to 2-inch reducing connection with cup-by-cup solder joints.\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 codes and IPC requirements. Shut off the water supply and depressurize the line before cutting or soldering. Clean and flux all mating surfaces before applying heat, and use lead-free solder for potable water applications as required by code. Allow the joint to cool fully before restoring pressure to the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Sweat Solder)\u003c\/li\u003e\n  \u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\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: CORED2122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51525274173746,"sku":"CORED2122","price":50.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2861748bfa8ae07cc2b85a3694335df7_38b3eefd-924d-4f30-b909-cd3a753fdada.jpg?v=1785469191","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cored2122-copper-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
