Manufactured from malleable iron with a black finish, this fitting transitions from a 1-1\/2 inch female iron pipe (FIP) inlet to a 3\/4 inch FIP outlet while redirecting flow at a 90 degree angle. Rated at Class 150 with a liquid and gas pressure rating of 300 psi, it handles the demands of both low-pressure gas lines and standard water piping. Licensed plumbers and pipefitters install this type of fitting when a direction change and pipe size reduction are required at the same connection point.\u003c\/p\u003e\u003cp\u003eThis reducing elbow is suited for threaded black iron pipe systems commonly found in natural gas supply lines, propane distribution, steam heating systems, and general water service piping. The black finish is standard for gas piping installations where coating integrity and corrosion resistance are required by local codes. It is appropriate for use in residential and light commercial systems where Class 150 malleable iron fittings are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90 degree elbow combines direction change and size reduction in a single fitting\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction rated to 300 psi liquid and gas pressure\u003c\/li\u003e\n\u003cli\u003eFemale iron pipe (FIP) threads on both ends for standard threaded pipe connections\u003c\/li\u003e\n\u003cli\u003eBlack finish suitable for gas line applications per common code requirements\u003c\/li\u003e\n\u003cli\u003eClass 150 rated for residential and light commercial service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for Class 150 threaded malleable iron pipe systems using 1-1\/2 inch to 3\/4 inch black iron pipe.\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 plumbing and mechanical codes, including IFGC requirements for gas line work. Shut off and depressurize the supply line completely before disassembling or threading any fitting. Apply an approved thread sealant or PTFE tape rated for the service medium before making up the threaded connections. Do not over-tighten; use a pipe wrench with a backup wrench on adjacent fittings to avoid stressing upstream joints.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 90 Degree Reducing Elbow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/2 x 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Threaded (FIP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: FIP\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\u003eClassification\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BK MUELLER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 520-174HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K MUELLER","offers":[{"title":"Default Title","offer_id":67906718007602,"sku":"520-174HC","price":34.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ca8c9f3fd32072b411d77f1b756dd0d_9e43773a-a75b-4498-82db-2951b97b8310.jpg?v=1791170772","url":"https:\/\/voomisupply.com\/products\/bk-mueller-520-174hc-90-reducing-elbow-1-1-2x3-4-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
