Rated at 150 lb, this fitting transitions a 1-1\/2 inch nominal pipe down to a 1 inch nominal pipe using female NPT (FNPT) threads on both ends. The galvanized finish provides corrosion resistance for use in wet or exposed environments. It is commonly installed by licensed plumbers and pipefitters in water distribution, HVAC hydronic, and general industrial piping systems.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial piping applications where a threaded reduction is needed between two straight runs of pipe. The FNPT end style on both ends allows for straightforward installation with standard pipe dope or PTFE tape. It is appropriate for use in water supply lines, low-pressure steam systems, and general fluid conveyance where a 150 lb malleable iron fitting meets system pressure and material requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1-1\/2 inch nominal to 1 inch nominal pipe in a single fitting\u003c\/li\u003e\n  \u003cli\u003eFemale NPT threads on both ends for standard threaded pipe connections\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class malleable iron construction\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for corrosion resistance in wet or exposed installations\u003c\/li\u003e\n  \u003cli\u003eConforms to FIG 3121R fitting pattern for reducing couplings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded replacement fitting for 1-1\/2 inch by 1 inch nominal FNPT malleable iron reducing coupling applications in 150 lb rated piping systems.\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 plumbing codes and IFGC or IPC requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus the appropriate number of turns for the pipe size without overtightening malleable iron. Inspect threads on mating pipe ends for damage before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread) 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: FIG 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: 811088418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524641161522,"sku":"GALRED1121I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0eabc50583c61a419da8ef4f53862fd_509427ab-7085-4b07-a478-f8891d32f1b2.jpg?v=1785453835","url":"https:\/\/voomisupply.com\/products\/sigma-811088418-reducing-coupling-1-1-2x1-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
