Rated at 150 lb, this fitting connects a 2-inch pipe to a 1\/2-inch pipe using female NPT (FNPT) threads on both ends. The galvanized finish provides corrosion resistance in wet and moderate-exposure environments. Malleable iron construction delivers reliable strength and thread engagement for standard-pressure service lines. This type of reducing coupling is installed by licensed plumbers and pipefitters performing line reductions in distribution or branch piping systems.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial piping applications where a step-down from 2-inch to 1\/2-inch nominal pipe is required. Typical uses include water distribution, gas branch lines, and mechanical room piping where galvanized malleable iron fittings are specified. The FNPT end style accepts standard tapered male pipe threads on the mating pipe segments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 2-inch nominal pipe to 1\/2-inch nominal pipe in a single fitting\u003c\/li\u003e\n  \u003cli\u003eFemale NPT (FNPT) threads on both ends for standard threaded pipe connections\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction rated at 150 lb pressure class\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for corrosion resistance in wet service environments\u003c\/li\u003e\n  \u003cli\u003eConforms to standard reducing coupling geometry per Figure 3121R\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 2-inch by 1\/2-inch NPT threaded pipe systems using 150 lb class malleable iron fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements. Shut off and depressurize the line before removing any existing fitting or making new connections. Apply appropriate thread sealant or PTFE tape to the male threads of the mating pipe before assembly. Do not over-torque threaded connections, as malleable iron fittings can crack if overtightened beyond hand-tight plus wrench turns appropriate to the pipe size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 2 x 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper) both ends\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  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: 3121R\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: 811089812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525447745842,"sku":"GALRED212I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0eabc50583c61a419da8ef4f53862fd_a61c5263-3b66-4ac6-bc9d-923e434fd31b.jpg?v=1785473989","url":"https:\/\/voomisupply.com\/products\/sigma-811089812-reducing-coupling-2x1-2-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
