It features female national pipe taper (FNPT) threads on all three outlets and a black oxide finish that provides basic corrosion resistance in dry or mildly exposed environments. The nominal size configuration is 1 inch run by 3\/4 inch run by 1\/2 inch branch, making it a standard reducing fitting for branching off a main line to a smaller service line. Licensed plumbers and pipefitters install this fitting in gas distribution, steam, and water piping systems where a directional branch at a reduced diameter is required.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is suited for residential and light commercial piping installations. It is commonly used where a 1-inch main line must continue while also feeding a 1\/2-inch branch line through a 3\/4-inch transition. Typical applications include natural gas distribution piping, steam heating systems, and general-purpose black iron pipe assemblies. The FNPT thread pattern is compatible with standard NPT-threaded pipe and fittings throughout these systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction handles thermal cycling and mechanical stress better than cast iron in threaded systems\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion protection suitable for interior and sheltered installations\u003c\/li\u003e\n  \u003cli\u003eFNPT threads on all three connections accept standard NPT male-threaded pipe\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class rating for use in low-pressure steam, gas, and water service\u003c\/li\u003e\n  \u003cli\u003eReducing configuration: 1 inch x 3\/4 inch x 1\/2 inch nominal for branching to smaller diameter lines\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 standard NPT black iron pipe systems in residential and light commercial plumbing, gas, and steam 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 fuel gas codes, including IPC and IFGC requirements where adopted. Shut off and depressurize the line fully before removing any existing fittings or threading in the new tee. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten threaded connections in malleable iron fittings, as this can crack the fitting body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 x 3\/4 x 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\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 Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Tee\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: 810041012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524306960690,"sku":"BLTRED13412I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_27ddc760-8a41-4c2b-a4bd-8f6468ae6c5b.jpg?v=1785445741","url":"https:\/\/voomisupply.com\/products\/sigma-810041012-malleable-iron-reducing-tee-1x3-4x1-2-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
