It features a female NPT (FNPT) end style on both ports and is rated at 150 lb, making it suitable for moderate-pressure service in commercial and industrial piping applications. Constructed from malleable iron with a black finish, this union provides reliable mechanical strength and a leak-resistant ground joint seat that allows easy disconnection and reconnection of pipe sections without disturbing the rest of the run. Licensed plumbers and pipefitters install this type of fitting as a standard component in maintainable piping systems.\u003c\/p\u003e\n\u003cp\u003eThis ground joint union is suited for use in residential and commercial piping systems where threaded iron pipe is specified. Common applications include gas distribution piping, steam lines, hydronic heating systems, and general industrial process piping. The 2 inch nominal size fits standard Schedule 40 and Schedule 80 black iron pipe. It is typically installed wherever future service access or equipment disconnection is anticipated.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFIG 3463 ground joint design provides a metal-to-metal seat for secure, leak-resistant sealing\u003c\/li\u003e\n  \u003cli\u003e2 inch nominal FNPT end connections for use with standard threaded iron pipe\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating suitable for moderate-pressure gas, steam, and liquid service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction offers high impact resistance and durability in demanding piping environments\u003c\/li\u003e\n  \u003cli\u003eBlack finish is standard for gas and steam piping applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit union for 2 inch nominal threaded malleable iron piping systems rated at 150 lb class service.\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 codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Shut off and depressurize the affected piping system completely before disassembling or installing any union fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before make-up, and tighten connections using pipe wrenches to achieve a wrench-tight fit. Do not over-tighten or use impact tools, as this can crack malleable iron fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3463\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 lb\u003c\/li\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIGMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 812509206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524584014130,"sku":"BLU2I-LF","price":21.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0211824fb5b74af7a4106487a55dca8e_d08d3b24-98fd-4f7f-a15a-a9d68572988f.jpg?v=1785452423","url":"https:\/\/voomisupply.com\/products\/sigma-812509206-fig-3463-ground-joint-union-2in-fnpt-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
