Built from domestic iron with a black finish, this union allows two sections of threaded pipe to be connected or disconnected without rotating the pipe itself. The extra-heavy designation indicates a heavier wall construction suited for higher-pressure or heavy-duty service conditions. At 1.20 pounds, it is a solid, durable fitting appropriate for commercial and industrial piping systems where standard-weight fittings may not meet service requirements.\u003c\/p\u003e\u003cp\u003eThis union is used in residential and commercial gas, steam, and liquid piping systems where threaded iron pipe is the specified material. It is a common component in boiler room piping, mechanical room assemblies, and industrial process lines where maintainable connections are required. Plumbers, pipefitters, and mechanical contractors install this fitting as part of threaded black iron pipe systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtra-heavy wall construction for demanding pressure and load conditions\u003c\/li\u003e\n\u003cli\u003eAll-iron body with black finish for use in gas and steam service\u003c\/li\u003e\n\u003cli\u003e1-inch threaded end connections for standard NPT pipe\u003c\/li\u003e\n\u003cli\u003eDomestic manufacture\u003c\/li\u003e\n\u003cli\u003eAllows pipe disconnection without rotating the run of pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1-inch threaded black iron pipe systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable codes such as the International Plumbing Code or International Fuel Gas Code. Shut off and depressurize the system fully before disassembling or installing any threaded union. Apply thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Tighten to the fitting manufacturer's recommended engagement using a pipe wrench — do not overtighten, as this can crack the iron body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Extra Heavy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.20 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 312704208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233548894514,"sku":"0312704208","price":99.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307627148.jpg?v=1780102869","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-312704208-black-iron-union-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
