Malleable iron construction provides the ductility and strength required for pressurized service, resisting cracking under mechanical stress. The black finish indicates this fitting is intended for gas distribution, fire suppression, or industrial piping applications where a galvanized coating is not required. Licensed plumbers and pipefitters install this type of union to allow future disassembly of a piping run without cutting pipe.\u003c\/p\u003e\n\u003cp\u003eThis union is suited for residential and commercial gas piping, steam, and hydronic heating systems where threaded fittings are specified. The 4-inch size fits large-diameter branch or main lines commonly found in commercial mechanical rooms, boiler rooms, and industrial process piping. Its three-piece union design allows the line to be broken and reassembled cleanly during maintenance or equipment replacement without disturbing adjacent fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003eBlack finish suitable for gas, steam, and industrial piping applications\u003c\/li\u003e\n  \u003cli\u003e4-inch pipe size for large-diameter threaded piping systems\u003c\/li\u003e\n  \u003cli\u003eThree-piece union design allows pipe disassembly without cutting\u003c\/li\u003e\n  \u003cli\u003eThreaded connection compatible with standard NPT pipe threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 4-inch threaded malleable iron piping systems in commercial and industrial 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 applicable local plumbing and mechanical codes, including IFGC requirements for gas piping systems. Shut off and depressurize the piping system completely before breaking or assembling any union connection. Apply listed pipe thread sealant or tape appropriate for the service type before threading components together. Do not overtighten the union nut, as malleable iron threads can be damaged by 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\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 777701351129\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: 35112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMI USA","offers":[{"title":"Default Title","offer_id":51347024216370,"sku":"35112","price":180.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554226.jpg?v=1782096807","url":"https:\/\/voomisupply.com\/products\/bmi-usa-35112-malleable-iron-black-pipe-union-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
