It is a pressure-rated fitting used in potable water supply, hydronic heating, and commercial plumbing distribution systems wherever a pipe size reduction is required inline. Licensed plumbers and mechanical contractors install this fitting as part of copper piping assemblies soldered per applicable codes. The cast copper construction provides the structural integrity and corrosion resistance required for long-term pressure service.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and commercial plumbing applications requiring a direct inline reduction from a 3-inch main to a 1-1\/4-inch branch or distribution line. Typical installations include domestic water supply systems, radiant and hydronic heating piping, and mechanical room distribution headers where multiple pipe sizes converge. Both ends accept standard copper tubing for sweat soldering with lead-free solder per current plumbing code requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast copper construction for high-pressure integrity and corrosion resistance in wet plumbing systems\u003c\/li\u003e\n  \u003cli\u003eC x C (sweat) end connections on both ends for standard lead-free solder installation\u003c\/li\u003e\n  \u003cli\u003eInline reducing configuration transitions 3-inch pipe to 1-1\/4-inch pipe in a single fitting\u003c\/li\u003e\n  \u003cli\u003ePressure-rated fitting suitable for water supply and hydronic system service\u003c\/li\u003e\n  \u003cli\u003eSold individually, no minimum multi-pack required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pressure fitting compatible with standard 3-inch and 1-1\/4-inch copper tubing (Type K, L, or M) joined by sweat soldering in potable water and hydronic pressure piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off and depressurize the system and drain all water from the line before cutting or soldering. Clean and flux both the fitting sockets and the tube ends before applying heat; use only lead-free solder where required by code for potable water service. Do not apply heat near combustible materials without proper shielding, and allow the joint to cool completely before repressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3 inches x 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x C (Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Pressure Fitting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.54 pounds\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: NIBCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B003250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51539493519666,"sku":"B003250","price":314.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5f7f1e6858394801f569ff41d08af00.jpg?v=1785841665","url":"https:\/\/voomisupply.com\/products\/nibco-b003250-cast-copper-reducer-3x1-1-4-in-c-x-c","provider":"Voomi Supply","version":"1.0","type":"link"}
