Rated at 150 lb, this fitting features female National Pipe Taper (FNPT) threads on both ends and accommodates a 2-inch nominal inlet reducing to a 3\/4-inch nominal outlet. The black oxide finish provides a degree of corrosion resistance suitable for standard indoor and dry service applications. Plumbers and pipefitters install this type of fitting in low-pressure water, steam, and general-purpose piping assemblies where a diameter reduction is required at a threaded joint.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial plumbing, fire protection, and industrial piping applications where malleable iron Class 150 threaded fittings are specified. It is appropriate for use in steam, water, oil, and air service within the pressure and temperature limits of a 150 lb malleable iron fitting. The FNPT thread form on both ends accepts standard NPT-threaded pipe, making it compatible with the broad range of pipe and fittings found in typical trade installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction provides durability and resistance to impact in threaded piping systems\u003c\/li\u003e\n  \u003cli\u003eFNPT threads on both ends accept standard NPT pipe for straightforward installation\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class rating suitable for low-pressure steam, water, oil, and air service\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for basic surface protection in dry or indoor environments\u003c\/li\u003e\n  \u003cli\u003eReduces from 2-inch nominal to 3\/4-inch nominal in a single fitting\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 Class 150 malleable iron threaded piping systems using standard NPT pipe connections.\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, including the IPC and IFGC where relevant. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly, and tighten to appropriate engagement without over-torquing malleable iron threads. Do not exceed the pressure and temperature ratings of the 150 lb fitting class for the intended service fluid.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: FNPT both ends\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 2 inches nominal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/4 inch nominal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\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: 810089607\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525511610674,"sku":"BLRED234I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0eabc50583c61a419da8ef4f53862fd_a564cb7f-52a0-4e8a-9b53-a9267acee5b5.jpg?v=1785476069","url":"https:\/\/voomisupply.com\/products\/sigma-810089607-reducing-coupling-2x3-4-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
