The black finish is applied through a standard black oxide or paint process common to malleable iron fittings used in gas, air, and water distribution lines. At 5.46 pounds, the casting delivers the structural mass expected of a heavy-duty reducing coupling. Licensed plumbers and pipefitters are the primary installers for this type of fitting in commercial and residential mechanical systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for use in threaded piping assemblies where a 4-inch line must transition to a 3-inch line, or where two pipe ends of matching size require a threaded union. Typical applications include gas distribution piping, compressed air systems, fire suppression rough-in, and general industrial or mechanical pipe runs where malleable iron fittings meet code requirements. The black finish makes this fitting appropriate for non-potable or gas service lines where a galvanized finish is not required or specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4x3 inch reducing configuration for transitioning between pipe sizes\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides durability and impact resistance in threaded piping systems\u003c\/li\u003e\n  \u003cli\u003eBlack finish suitable for gas, air, and non-potable water piping applications\u003c\/li\u003e\n  \u003cli\u003eHeavy casting at 5.46 pounds supports high-demand mechanical piping installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fitting for use in threaded malleable iron piping systems requiring a 4x3 inch reducing coupling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of malleable iron pipe fittings should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC) where applicable. Always shut off the relevant gas, air, or water supply and depressurize the line before making any connections. Apply appropriate thread sealant or PTFE tape rated for the intended service medium before threading the fitting. Do not over-torque threaded connections, as malleable iron threads can crack under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4x3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.46 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 777701350566\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: BMI USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMI USA","offers":[{"title":"Default Title","offer_id":51342988280114,"sku":"35056","price":71.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554098.jpg?v=1782012930","url":"https:\/\/voomisupply.com\/products\/bmi-usa-35056-4x3-inch-black-malleable-iron-pipe-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
