Constructed from black malleable iron, this fitting connects a 1.25-inch female threaded port to a 0.5-inch female threaded port, making it suitable for gas distribution lines, compressed air systems, and general industrial piping. The black finish is standard for gas-line applications. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting during rough-in and service work where a directional change and a size reduction are needed at the same junction point.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial piping installations where threaded black iron pipe is specified. Common applications include natural gas supply lines, propane distribution, and compressed air headers where pipe diameter changes occur at elbows. The female-threaded connections on both ends accept standard NPT male pipe threads on the mating pipe or nipple.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombines a 90-degree direction change with a reducing connection in one fitting\u003c\/li\u003e\n  \u003cli\u003e1.25-inch female threaded inlet and 0.5-inch female threaded outlet\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003eBlack finish is standard for gas piping systems per common code requirements\u003c\/li\u003e\n  \u003cli\u003eFemale NPT threads on both ends for use with standard threaded black iron pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded fitting compatible with standard NPT black iron pipe systems requiring a 1.25-inch to 0.5-inch reducing 90-degree elbow connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, IFGC, or IPC requirements. Shut off and depressurize the gas or fluid supply before disassembling or threading any fittings. Apply appropriate thread sealant or PTFE tape rated for the service medium to all NPT connections before assembly. Do not overtighten threaded connections, 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\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\u003eEnd Connection\u003c\/strong\u003e: Female Threaded x Female Threaded (FPT x FPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 Degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Reducing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Inlet)\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Outlet)\u003c\/strong\u003e: 0.5 inches\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 520-163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51283986776370,"sku":"520-163","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277080.png?v=1781065144","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-520-163-reducing-90-degree-elbow-fpt","provider":"Voomi Supply","version":"1.0","type":"link"}
