Configured in a 1 x 1 x 1\/2 inch nominal size, it allows a branch takeoff at half the diameter of the run pipe without requiring additional bushings in most standard installations. The fitting carries a 150 lb pressure rating and features a black oxide finish that provides basic corrosion resistance for indoor or protected environments. All three ports use Female National Pipe Taper (FNPT) threading, making it compatible with standard tapered male pipe threads. Licensed plumbers and pipefitters install this type of fitting in gas, water, and air distribution systems.\u003c\/p\u003e\u003cp\u003eThis reducing tee is suited for residential and light commercial plumbing, HVAC hydronic piping, compressed air lines, and low-pressure gas distribution where a threaded branch connection is required. The 1 inch run ports accommodate standard 1 inch pipe, while the 1\/2 inch branch port serves smaller-diameter supply or takeoff lines. The malleable iron construction handles the mechanical stress of assembly and light vibration better than cast iron in the same pressure class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 x 1 x 1\/2 inch nominal reducing configuration for run-to-branch diameter reduction\u003c\/li\u003e\n\u003cli\u003eFNPT threads on all three ports for standard tapered male pipe thread engagement\u003c\/li\u003e\n\u003cli\u003e150 lb pressure rating suitable for low-pressure gas, water, and air service\u003c\/li\u003e\n\u003cli\u003eMalleable iron body offers improved ductility and impact resistance compared to cast iron\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides surface protection in dry or protected indoor installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for threaded malleable iron pipe systems using 1 inch run pipe and 1\/2 inch branch pipe in 150 lb service class applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the pipe system completely before disassembling or adding fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten; use a pipe wrench with a backup wrench on the adjacent fitting to avoid stressing the piping system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 x 1 x 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper) all ports\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 Oxide\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 810040006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525035917618,"sku":"BLTRED1112I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_5ef008a7-3d1a-4013-b529-123c8a58af3c.jpg?v=1785462999","url":"https:\/\/voomisupply.com\/products\/sigma-810040006-malleable-iron-reducing-tee-1x1x1-2-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
