Manufactured to FIG 3105R specifications, this fitting connects three sections of pipe at a tee junction while reducing the branch outlet from 1-1\/2 inches to 1-1\/4 inches nominal. The run connections measure 1-1\/2 inches nominal on both ends. It carries a 150 lb pressure rating and features female national pipe taper (FNPT) threads on all three ports. The galvanized finish provides corrosion resistance for installations in moderate-exposure environments such as mechanical rooms, gas distribution headers, and water supply lines.\u003c\/p\u003e\u003cp\u003eThis reducing tee is suited for residential and light commercial mechanical installations where a branch line requires a size transition off a main run. Typical applications include plumbing supply lines, compressed air distribution, hydronic heating headers, and low-pressure gas piping where a threaded reducing branch connection is needed. Licensed plumbers and pipefitters install this fitting in new construction and retrofit work following applicable IPC and IFGC requirements for threaded fittings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFIG 3105R malleable iron construction rated to 150 lb\u003c\/li\u003e\n\u003cli\u003eReducing branch outlet: 1-1\/4 inches nominal, run ports: 1-1\/2 inches nominal on both ends\u003c\/li\u003e\n\u003cli\u003eFNPT threads on all three ports for standard threaded pipe assembly\u003c\/li\u003e\n\u003cli\u003eGalvanized finish for corrosion resistance in moderate-exposure service\u003c\/li\u003e\n\u003cli\u003eSuitable for gas, air, water, and steam applications within pressure rating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threaded fitting replacement compatible with standard 150 lb malleable iron threaded piping systems using NPT-threaded pipe and fittings per ASME B16.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly and tighten to standard pipe-thread engagement using a pipe wrench. Do not over-torque, as malleable iron fittings can crack if over-stressed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3105R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1-1\/2 x 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper) all three 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: Galvanized\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: 811045418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525133435186,"sku":"GALTRED112112114I-LF","price":16.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_300faae6-f0df-440f-9cb9-891dd562c9d2.jpg?v=1785465236","url":"https:\/\/voomisupply.com\/products\/sigma-811045418-galvanized-reducing-tee-1-1-2x1-1-2x1-1-4-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
