Sized at 1-1\/2 x 1-1\/4 inches nominal with female NPT (FNPT) ends, this fitting connects two pipes of differing diameters while keeping one side of the bore flat, which is critical for maintaining proper drainage slope and preventing air pockets in horizontal runs. The eccentric offset design is a standard choice in HVAC hydronic piping, steam systems, and industrial plumbing. A licensed plumber or pipefitter typically handles installation in commercial and residential mechanical systems.\u003c\/p\u003e\n\u003cp\u003eThis eccentric reducer fits into Schedule 40 standard-wall threaded pipe assemblies and is rated for service from -20 to 150 degrees F. It is suited for steam, water, and compatible fluid distribution lines where reducing a 1-1\/2 inch line down to 1-1\/4 inch is required. The black oxide finish provides a basic level of surface protection. Typical applications include boiler piping, hydronic heating distribution, and process piping in light industrial environments where cast iron fittings meet project specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEccentric bore offset keeps one side flat for proper drainage slope on horizontal pipe runs\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 x 1-1\/4 inch nominal sizing with FNPT threaded ends for standard pipe thread connections\u003c\/li\u003e\n  \u003cli\u003e125 lb pressure class rated to 175 psi\u003c\/li\u003e\n  \u003cli\u003eSchedule 40 \/ standard wall compatible\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -20 to 150 degrees F\u003c\/li\u003e\n  \u003cli\u003eCast iron construction with black oxide finish for corrosion surface treatment\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement eccentric reducing coupling for Schedule 40 standard-wall threaded cast iron pipe systems in the 125 lb pressure class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC code requirements. Depressurize and drain the pipe system fully before removing any existing fittings or installing this coupling. Apply an appropriate thread sealant or PTFE tape to the male pipe threads before makeup. Do not over-torque threaded connections in cast iron fittings, as the material is not ductile and can crack under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 125 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 175 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: SCH 40 \/ Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -20 to 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: ASC ENGINEERED SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300153608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51268783341874,"sku":"0300153608","price":327.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/Cast_Iron_Eccentric_Reducer_Large_0a50d3ef-6132-4fa8-a148-8f81deb5e03f.jpg?v=1780705639","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-300153608-eccentric-reducer-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
