The fitting connects a 1-1\/2 inch run on both ends to a reduced 3\/4 inch branch outlet, all with female NPT (FNPT) threads. A black oxide finish provides baseline corrosion resistance for indoor and general-purpose applications. Plumbers and pipefitters install this fitting where a branch takeoff at a smaller diameter is required without transitioning to a separate reducing bushing or coupling. The malleable iron body handles the mechanical stress of threaded assembly and typical system pressures in low-pressure piping configurations.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is suited for residential and light commercial piping systems including gas distribution, steam, compressed air, and water service lines where threaded malleable iron fittings are specified. The FNPT thread pattern on all three outlets allows direct connection to standard NPT-threaded pipe and fittings. It is commonly used in branch line configurations where a main run must continue at full size while a smaller branch feeds a secondary zone, appliance, or instrument tap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing tee configuration: 1-1\/2 inch x 1-1\/2 inch run with 3\/4 inch branch outlet\u003c\/li\u003e\n  \u003cli\u003eFemale NPT threads on all three ports for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class malleable iron construction\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for general-purpose indoor service\u003c\/li\u003e\n  \u003cli\u003eFIG 1105R pattern for drop-in replacement in existing threaded systems\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 malleable iron threaded pipe systems using standard NPT pipe and fittings.\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 mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the system completely before disassembling any existing fittings. Apply thread sealant tape or pipe compound rated for the service fluid to all male threads before assembly. Do not over-torque threaded connections, as malleable iron threads can crack under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 1105R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1-1\/2 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 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\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: 810045807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524269474098,"sku":"BLTRED11211234I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_321cb4c5-1d6b-450f-b9be-f5131e0df6a9.jpg?v=1785445611","url":"https:\/\/voomisupply.com\/products\/sigma-810045807-malleable-iron-reducing-tee-1-1-2x1-1-2x3-4-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
