Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting handles demanding service conditions in both residential and light commercial installations. The galvanized finish provides corrosion resistance. Connecting a 1\/2-inch line to a 1\/8-inch line, it is installed by licensed plumbers and pipefitters wherever a diameter transition is needed in a threaded iron pipe assembly.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for use in plumbing, HVAC hydronic, gas distribution, and steam piping systems where a transition from 1\/2-inch to 1\/8-inch pipe is required. Its threaded end connections comply with standard NPT pipe thread configurations, making it compatible with other threaded malleable iron and black iron fittings. It is commonly found in boiler rooms, mechanical rooms, and utility piping runs in residential and commercial buildings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and durability in pressurized piping\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for corrosion resistance in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eRated 300 psi for liquid and gas service\u003c\/li\u003e\n  \u003cli\u003eRated 150 psi for steam service\u003c\/li\u003e\n  \u003cli\u003eThreaded end connections for standard NPT pipe assembly\u003c\/li\u003e\n  \u003cli\u003eClass 150 fitting classification for broad system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for threaded malleable iron pipe systems requiring a 1\/2-inch to 1\/8-inch reducing connection.\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 plumbing codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where applicable. Shut off and depressurize the system completely before removing or installing any fitting. Apply appropriate pipe thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings 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: Reducing Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/2 x 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Threaded (NPT)\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\u003eSteam Pressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\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: 511-330HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K MUELLER","offers":[{"title":"Default Title","offer_id":67911970292018,"sku":"511-330HC","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6af8adce7a8c1ceea460a2893d1823e.jpg?v=1791223864","url":"https:\/\/voomisupply.com\/products\/bk-mueller-511-330hc-reducing-coupling-1-2x1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
