This hex bushing reduces a 2-inch female threaded fitting down to a 1-inch male threaded connection, making it a standard component in gas and liquid piping assemblies. The malleable iron construction provides the ductility needed to withstand mechanical stress and vibration in piping systems, while the black finish offers corrosion resistance suitable for interior installations. With a pressure rating of 300 psi, it handles the demands of most commercial and residential plumbing and gas distribution lines. Plumbers and pipefitters install this bushing where a reduction between threaded pipe sizes is required.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in residential and light commercial piping systems where threaded iron pipe is the standard connection method. Common applications include natural gas distribution, compressed air lines, and water supply piping that uses malleable iron fittings throughout. The Class 150 rating and 300 psi pressure capacity make it appropriate for a wide range of service conditions. It is designed to thread directly into standard NPT-threaded fittings, valves, and pipe nipples using conventional pipe wrenches and thread sealant or PTFE tape.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003eBlack finish suitable for interior gas and plumbing applications\u003c\/li\u003e\n  \u003cli\u003eThreaded connections on both ends for standard NPT compatibility\u003c\/li\u003e\n  \u003cli\u003eClass 150 rated with a 300 psi pressure rating for liquid and gas service\u003c\/li\u003e\n  \u003cli\u003eReduces 2-inch female thread to 1-inch male thread 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 fitting for standard NPT threaded malleable iron piping systems in residential and commercial applications.\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 local codes and IFGC or IPC requirements for the intended service. Shut off all gas or fluid supply and relieve system pressure before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly and tighten with a pipe wrench to achieve a leak-free connection. Do not over-tighten, as this can crack fittings or damage threads.\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 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Threaded (NPT)\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 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: 521-985HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K MUELLER","offers":[{"title":"Default Title","offer_id":67906291302706,"sku":"521-985HN","price":22.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b6dbb342b4f84d76605deb8bb331f40.jpg?v=1791166998","url":"https:\/\/voomisupply.com\/products\/bk-mueller-521-985hn-black-iron-pipe-bushing-2x1-in-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
