Manufactured from 304L stainless steel, this fitting connects a 3-inch pipe to a 1-1\/4-inch pipe using butt weld end connections on both ends. The eccentric geometry positions the flat side of the reducer along one plane, which is critical in horizontal liquid lines where preventing air pockets or maintaining a consistent flow invert elevation is required. At 0.52 pounds, it is a compact, weldable component suited for professional fabrication and installation work.\u003c\/p\u003e\n\u003cp\u003eThis eccentric reducer is used in commercial and industrial piping applications including HVAC hydronic systems, process piping, plumbing distribution, and sanitary or chemical service lines where 304L stainless steel is specified for corrosion resistance. The butt weld end connections require field welding by a qualified pipefitter or welder. Schedule 10 wall thickness makes this fitting appropriate for lower-pressure service conditions typical of HVAC and general process piping rather than high-pressure steam or hydraulic systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304L stainless steel construction provides excellent corrosion resistance in wet and chemical environments\u003c\/li\u003e\n  \u003cli\u003eEccentric design maintains a flat bottom or flat top orientation to control flow invert and prevent air trapping in horizontal runs\u003c\/li\u003e\n  \u003cli\u003eButt weld end connections on both ends for full-penetration welded joints\u003c\/li\u003e\n  \u003cli\u003eSchedule 10 wall thickness suited for low-to-moderate pressure piping service\u003c\/li\u003e\n  \u003cli\u003e3 x 1-1\/4 inch reduction in a single fitting eliminates the need for multiple reducers in series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style butt weld eccentric reducer for Schedule 10 stainless steel piping systems transitioning from 3-inch to 1-1\/4-inch nominal pipe size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a qualified pipefitter or certified welder following applicable codes such as ASME B31.1, B31.3, or B31.9 depending on the service application. Isolate and depressurize the piping system completely before cutting in or fitting up this reducer. Verify pipe schedule and material compatibility before welding, as mixing schedules or alloy grades can compromise joint integrity. Orient the eccentric reducer with the flat side up or flat side down as required by the system design to maintain proper drainage or venting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Eccentric Reducer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3 x 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304L Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Butt Weld x Butt Weld\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.52 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01413-4820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51538292113714,"sku":"01413-4820","price":828.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c7da2a8539f454e6c688762880367b7.jpg?v=1785822067","url":"https:\/\/voomisupply.com\/products\/merit-brass-01413-4820-eccentric-reducer-3x1-1-4-in-304l-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
