It carries a Class 150 pressure rating and is suitable for liquid and gas service up to 300 psi. The black finish is applied for corrosion resistance in standard service environments. This bushing is installed by licensed plumbers, pipefitters, and gas service technicians working on threaded iron pipe systems.\u003c\/p\u003e\n\u003cp\u003eThis bushing fits into residential and light commercial piping applications where a threaded reducer is needed between a 1-inch fitting and a 3\/8-inch branch or component. Common install scenarios include gas supply lines, compressed air distribution, and water supply piping where malleable iron fittings are specified. Its Class 150 rating makes it appropriate for standard service pressures found in most residential and commercial mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and durability in threaded pipe systems\u003c\/li\u003e\n  \u003cli\u003eBlack finish for corrosion resistance in standard service conditions\u003c\/li\u003e\n  \u003cli\u003eClass 150 rated with a 300 psi liquid and gas pressure rating\u003c\/li\u003e\n  \u003cli\u003eThreaded end connections on both ends for standard NPT installation\u003c\/li\u003e\n  \u003cli\u003eReduces from 1-inch female thread to 3\/8-inch male thread\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 standard threaded malleable iron pipe systems rated at Class 150 service conditions.\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 and mechanical codes, including IFGC requirements when used on gas lines. Shut off gas or water supply and depressurize the line completely before removing or installing any fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eFitting Type\u003c\/strong\u003e: Bushing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1 x 3\/8 inches\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\u003ePressure Rating\u003c\/strong\u003e: 300 psi (liquid and gas)\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: 521-952HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K MUELLER","offers":[{"title":"Default Title","offer_id":67907048440114,"sku":"521-952HC","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8146eac4315245cceb84617f369af45.jpg?v=1791173791","url":"https:\/\/voomisupply.com\/products\/bk-mueller-521-952hc-threaded-bushing-1-x-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
