It features a 1 x 1 x 3\/4 inch nominal configuration, meaning the run is 1 inch in diameter and the branch outlet reduces to 3\/4 inch. All three ports use female national pipe taper (FNPT) threads for secure, leak-resistant connections. Rated at 150 lb, this fitting is built from malleable iron, which provides the ductility needed to absorb vibration and mechanical stress in live piping systems. The black finish is standard for non-potable applications. Plumbers and pipefitters install this fitting where a branch line steps down in diameter from the main run.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is suited for low-pressure gas distribution, compressed air, and general industrial piping systems where a directional branch takeoff is required at a reduced pipe size. It is a common component in commercial and light industrial installations where 150 lb class malleable iron fittings meet system pressure and temperature requirements. The FNPT thread pattern is compatible with standard NPT-threaded pipe and fittings throughout a system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 1 x 3\/4 inch nominal reducing configuration with 3\/4 inch branch outlet\u003c\/li\u003e\n  \u003cli\u003eFNPT threads on all three ports for standard NPT pipe compatibility\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class malleable iron construction\u003c\/li\u003e\n  \u003cli\u003eBlack finish suited for gas and non-potable piping applications\u003c\/li\u003e\n  \u003cli\u003eMalleable iron body resists cracking under vibration and mechanical load\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 150 lb class black malleable iron threaded pipe systems using standard NPT connections.\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, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on service type. Shut off and depressurize the line completely before disassembling any portion of the system. Apply an appropriate thread sealant or PTFE tape rated for the service medium before making up all FNPT connections. Do not overtighten threaded fittings, 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\u003eNominal Size\u003c\/strong\u003e: 1 x 1 x 3\/4 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 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: 810039818\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525350490418,"sku":"BLTRED1134I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_b733efbe-80f7-41bf-b666-e3dd643054a8.jpg?v=1785471271","url":"https:\/\/voomisupply.com\/products\/sigma-810039818-reducing-pipe-tee-1x1x3-4-in-fnpt-malleable-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
