It features female National Pipe Taper (FNPT) threads on both ends and transitions from a 1-1\/2 inch nominal inlet to a 3\/4 inch nominal outlet. Rated at 300 psi and classified at 150 lb pressure class, this reducer is built for reliable service in demanding plumbing and mechanical applications. The black finish is standard for non-galvanized malleable iron fittings used in gas and liquid piping systems. It is installed by licensed plumbers and pipefitters working on commercial and residential mechanical systems.\u003c\/p\u003e\u003cp\u003eThis concentric reducer is suited for residential and light commercial piping installations where a threaded reduction is needed between two pipe sizes in-line. Common applications include water supply lines, steam systems, gas distribution piping, and mechanical room installations. Its concentric design keeps the pipe centerlines aligned, which is important in tight or structured pipe runs. Domestically manufactured, it meets the dimensional and material standards expected in trade plumbing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eConcentric reducer design maintains centerline alignment between inlet and outlet pipes\u003c\/li\u003e\n\u003cli\u003eFNPT threads on both ends for standard threaded pipe connections\u003c\/li\u003e\n\u003cli\u003e300 psi pressure rating at 150 lb pressure class for reliable service\u003c\/li\u003e\n\u003cli\u003eTemperature range of -20 to 150 degrees F suits a broad range of piping applications\u003c\/li\u003e\n\u003cli\u003eBlack malleable iron construction provides strength and machinability\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for threaded malleable iron pipe systems using 1-1\/2 inch to 3\/4 inch nominal pipe sizes with FNPT connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) as required by the system type. Shut off and depressurize the piping system completely before removing or installing any fitting. Apply an appropriate pipe thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -20 to 150 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Coupling (Concentric Reducer)\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: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69029134850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS","offers":[{"title":"Default Title","offer_id":51621291032882,"sku":"69029134850","price":17.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b62aba060be62caefb9538ba94745c96_2628d5d2-6da8-44f5-b6c5-8e4923330089.jpg?v=1787352469","url":"https:\/\/voomisupply.com\/products\/mars-69029134850-concentric-reducer-1-1-2-x-3-4-in-malleable-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
