It transitions from a 4-inch female threaded inlet to a 1-1\/2-inch female threaded outlet, allowing plumbers and pipefitters to reduce line size within a run without additional fittings. The black coating provides corrosion resistance suitable for gas, water, and industrial piping applications. At 4.90 pounds, this is a solid, heavy-duty fitting intended for permanent installation in commercial or residential systems where a reliable threaded reducing connection is required.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for use in threaded black iron piping systems commonly found in natural gas distribution, compressed air lines, fire suppression headers, and hydronic heating systems. The malleable iron construction allows the fitting to withstand mechanical stress and vibration better than cast iron alternatives. Licensed plumbers, gas fitters, and pipefitters typically install this type of fitting in both new construction and retrofit applications where pipe size reduction is needed inline.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 4-inch to 1-1\/2-inch in a single threaded fitting\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction offers superior impact and vibration resistance versus cast iron\u003c\/li\u003e\n  \u003cli\u003eBlack coating provides corrosion protection for gas and water service\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured for consistent quality and dimensional conformance\u003c\/li\u003e\n  \u003cli\u003eWeighs 4.90 pounds, reflecting heavy-duty wall thickness appropriate for this pipe size range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-install fitting for standard NPT threaded black iron piping systems using 4-inch and 1-1\/2-inch nominal pipe sizes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or certified gas fitter in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to male threads before makeup, and tighten to proper engagement using a pipe wrench sized for the fitting. Do not overtighten malleable iron fittings, as excessive force can crack the fitting body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 4 inches x 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Reducing Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.90 pounds\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: 310093208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51234042708274,"sku":"0310093208","price":206.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307627182.jpg?v=1780115962","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-310093208-reducing-coupling-4x1-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
