It connects a 2-inch pipe to a 1-inch pipe using female iron pipe (FIP) threads on both ends. Rated at Class 150 with a pressure rating of 300 psi, this fitting handles demanding service conditions in both residential and light commercial installations. The black finish is standard for gas piping applications. Plumbers and pipefitters install this coupling where a reduction in pipe diameter is required within a threaded iron pipe system.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is suited for use in natural gas, propane, water, and air distribution systems where malleable iron fittings are specified. It is commonly installed in residential gas lines, commercial gas distribution headers, and industrial piping networks that require a step-down from 2-inch to 1-inch pipe. The threaded FIP connection allows installation using standard pipe wrenches without special tooling, making it a straightforward field fit for service and retrofit work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMalleable iron construction provides strength and impact resistance in threaded piping systems\u003c\/li\u003e\n\u003cli\u003eBlack finish meets standard requirements for gas piping applications\u003c\/li\u003e\n\u003cli\u003eFIP threads on both ends for connection to standard NPT male-threaded pipe\u003c\/li\u003e\n\u003cli\u003e300 psi pressure rating suitable for gas and liquid service\u003c\/li\u003e\n\u003cli\u003eClass 150 classification for use in standard commercial and residential piping\u003c\/li\u003e\n\u003cli\u003eReduces from 2-inch to 1-inch pipe in a single fitting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-stock reducing coupling for malleable iron threaded pipe systems using NPT connections in Class 150 service.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable code requirements such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the pipeline completely before removing or installing any fitting. Apply listed pipe thread sealant or tape rated for the service medium to all male threads before assembly. Do not overtighten with pipe wrenches, as malleable iron threads can be damaged by excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Coupling\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 (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: 521-385HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K MUELLER","offers":[{"title":"Default Title","offer_id":67915539710258,"sku":"521-385HC","price":34.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23f4d44d1b117952780bd56bcdc6beec.jpg?v=1791254001","url":"https:\/\/voomisupply.com\/products\/bk-mueller-521-385hc-reducing-coupling-2x1-in-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
