It carries a Class 150 pressure rating with a working pressure of 300 psi, making it suitable for both liquid and gas service in standard commercial and residential piping systems. The black finish is achieved through a standard black lacquer or oil treatment process common to malleable iron fittings. Licensed plumbers and pipefitters install this type of bushing when reducing pipe size within a threaded iron piping system.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in residential and light commercial gas and liquid piping applications where a threaded iron reduction fitting is required. Typical installations include gas distribution lines, water supply systems, and industrial piping where malleable iron fittings and Class 150 ratings are specified. The 2-inch male thread connects to an existing 2-inch female-threaded fitting, while the 3\/4-inch female thread accepts the downstream pipe or fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and thread integrity under torque\u003c\/li\u003e\n  \u003cli\u003e300 psi liquid and gas pressure rating\u003c\/li\u003e\n  \u003cli\u003eClass 150 classification for standard piping systems\u003c\/li\u003e\n  \u003cli\u003eThreaded end connections on both male and female ends\u003c\/li\u003e\n  \u003cli\u003eBlack finish suitable for gas and liquid service piping\u003c\/li\u003e\n  \u003cli\u003eReduces from 2-inch to 3\/4-inch pipe size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-use threaded bushing for Class 150 malleable iron piping systems requiring a 2-inch by 3\/4-inch reduction connection in gas or liquid service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter in accordance with local plumbing codes and the International Fuel Gas Code (IFGC) where applicable. Shut off all gas or liquid supply and relieve system pressure before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-torque the fitting, as malleable iron threads can crack under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Bushing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 2 x 0.75 inches\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\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid and Gas Pressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: BK MUELLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 521-984HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K MUELLER","offers":[{"title":"Default Title","offer_id":67912152809778,"sku":"521-984HC","price":15.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0eb329027a971eca6108bd1ec83c28d2.jpg?v=1791228002","url":"https:\/\/voomisupply.com\/products\/bk-mueller-521-984hc-threaded-malleable-iron-bushing-2x0-75in","provider":"Voomi Supply","version":"1.0","type":"link"}
