Manufactured under the Ward Mfg product line, this fitting transitions from a 2-1\/2 inch nominal inlet to a 1-1\/4 inch nominal outlet using National Pipe Straight (NPS) threaded ends. Rated at 125 lb pressure class and conforming to ASME B16.4 dimensional standards, it is suited for general-purpose piping systems where an offset centerline between the two pipe runs is required. Licensed plumbers and pipefitters are the primary installers of this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis eccentric reducing coupling is used in residential and light commercial piping applications including water distribution, drain and vent systems, and industrial process lines where gravity drainage alignment is critical. The eccentric design keeps the bottom of the pipe bore level, which helps maintain proper flow and drainage pitch across the reduction. It is a domestically manufactured fitting and carries certifications meeting several ASME, ASTM, and federal standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEccentric reduction keeps pipe bottom level for proper drainage alignment\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 x 1-1\/4 inch nominal NPS threaded ends for standard pipe connections\u003c\/li\u003e\n  \u003cli\u003e125 lb pressure class cast iron construction for durability in general piping service\u003c\/li\u003e\n  \u003cli\u003eBlack finish provides corrosion resistance for above-ground applications\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured to ASME B16.4 dimensional and ASME B1.20.1 thread standards\u003c\/li\u003e\n  \u003cli\u003eMeets AB-1953, ASTM A126, and Federal Spec WW-P-501 requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded reducer for cast iron NPS piping systems rated at 125 lb pressure class in residential and commercial plumbing and mechanical applications.\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 the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten cast iron fittings, as the material is not ductile and can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 2-1\/2 x 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: NPS (National Pipe Straight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 125 lb\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Eccentric Reducer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AB-1953, ASME B16.4 Dimension, ASME B1.20.1 Thread, ASTM A126 Cast Iron, Federal Spec WW-P-501\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: 300155801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51268352573746,"sku":"0300155801","price":697.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/Ward_1BX1NER.jpg?v=1780703130","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-300155801-eccentric-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
