Sized at 3 x 1-1\/4 inches, this fitting transitions flow from a larger to a smaller pipe diameter while offsetting the centerline — a critical characteristic for pump suction lines and horizontal runs where air pockets and drainage must be controlled. Constructed from 316L stainless steel, it offers low carbon content that minimizes carbide precipitation during welding, making it well suited for corrosive service environments. Licensed plumbers, pipefitters, and industrial pipe welders are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis eccentric reducer is appropriate for commercial and industrial piping applications including process piping, HVAC chilled and condenser water systems, chemical transfer lines, and sanitary or marine installations where 316L stainless steel is specified for corrosion resistance. The butt weld end connections on both ends allow full-penetration welds for a flush, high-integrity joint. Schedule 10 wall thickness suits moderate-pressure service in a range of wet mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316L stainless steel construction resists corrosion and pitting in aggressive media\u003c\/li\u003e\n  \u003cli\u003eLow carbon 316L grade minimizes carbide precipitation in the heat-affected weld zone\u003c\/li\u003e\n  \u003cli\u003eEccentric offset keeps the bottom of pipe level, preventing air lock on suction lines and aiding drainage on horizontal runs\u003c\/li\u003e\n  \u003cli\u003eButt weld x butt weld ends allow full-penetration welds for leak-free, high-strength joints\u003c\/li\u003e\n  \u003cli\u003eSchedule 10 wall thickness for moderate-pressure commercial and industrial service\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.52 pounds for easier handling during fitup and tacking\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 requiring a 3 x 1-1\/4 inch transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter or certified pipe welder following applicable codes such as ASME B31.3 for process piping or ASME B31.9 for building services piping. Shut down and depressurize the piping system completely before cutting into existing lines. Fit and tack in proper orientation — flat side down for horizontal pump suction runs, flat side up for gravity drainage applications — before completing full-penetration butt welds. Post-weld passivation of 316L stainless steel joints is standard practice in corrosive service environments.\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: 316L 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: 01613-4820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51539431522610,"sku":"01613-4820","price":1057.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c7da2a8539f454e6c688762880367b7_9060cdc5-5e8c-45c2-b2b7-d5dc38ba6376.jpg?v=1785840139","url":"https:\/\/voomisupply.com\/products\/merit-brass-01613-4820-eccentric-reducer-3x1-1-4-in-316l-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
