Rated at 150 lb, this fitting transitions from a 1\/2 inch nominal female connection to a 1\/4 inch nominal female connection using FNPT (female national pipe thread) ends on both sides. The galvanized finish provides corrosion resistance suited for general-purpose plumbing and mechanical piping applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting in low-pressure piping assemblies.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in residential and light commercial piping systems where a threaded reduction in line size is required. Typical applications include water supply lines, compressed air distribution, and low-pressure gas piping where a 1\/2 inch to 1\/4 inch size reduction is needed at a threaded connection point. The 150 lb pressure rating makes it suitable for standard service conditions in these system types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1\/2 inch nominal to 1\/4 inch nominal in a single threaded fitting\u003c\/li\u003e\n  \u003cli\u003eFNPT end style on both connections for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating for general-purpose low-pressure service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction for durability in threaded mechanical connections\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for added corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation threaded reducing coupling for 1\/2 inch by 1\/4 inch nominal FNPT piping systems rated at 150 lb service.\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 plumbing codes such as the IPC. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not overtighten, as malleable iron fittings can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/2 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread)\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\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: 811085612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525377098034,"sku":"GALRED1214I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0eabc50583c61a419da8ef4f53862fd_86e4265f-c494-432b-8bda-d055a23e9a7d.jpg?v=1785472141","url":"https:\/\/voomisupply.com\/products\/sigma-811085612-pipe-reducing-coupling-1-2x1-4-in-fnpt-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
