Constructed from malleable iron with a black oxide finish, it carries a 150 lb pressure rating suitable for general-purpose piping systems. The hex head profile allows full wrench engagement for secure installation without slipping. Plumbers and pipefitters use this bushing when transitioning between pipe sizes in threaded iron piping assemblies in both commercial and residential applications.\u003c\/p\u003e\n\u003cp\u003eThis bushing fits standard threaded iron pipe systems where a size reduction from 2-inch to 1-1\/2-inch is required. It is appropriate for use in water distribution, low-pressure steam, hydronic heating, and general industrial piping. The MNPT x FNPT end configuration allows the bushing to thread into a female-threaded fitting or valve body while accepting a male-threaded pipe or fitting on the outlet side. It is a common component in mechanical rooms, boiler rooms, and fire protection piping where malleable iron fittings are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch MNPT inlet threads down to 1-1\/2-inch FNPT outlet for in-line pipe size reduction\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and resistance to mechanical stress in threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers corrosion resistance appropriate for typical indoor piping environments\u003c\/li\u003e\n  \u003cli\u003eHex head profile allows full wrench engagement for leak-free thread makeup\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating meets standard requirements for general-purpose threaded iron piping\u003c\/li\u003e\n  \u003cli\u003eFIG 3383 standard dimensions ensure interchangeability with compatible malleable iron fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard FIG 3383 hex head pipe bushing for use in 150 lb malleable iron threaded piping systems with 2-inch MNPT and 1-1\/2-inch FNPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter. Isolate and depressurize the piping system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly and tighten to proper engagement using a pipe wrench on the hex head. Do not overtighten, as malleable iron threads can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 2 x 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: MNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 lb\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 Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure\u003c\/strong\u003e: FIG 3383\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: SIGMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 818907685\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525331648818,"sku":"BLBUSH2112I-LF","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89b042a6433f59f3a7393de72ad9a709_6d19f072-ca29-4e5d-8460-12d3a2268236.jpg?v=1785470784","url":"https:\/\/voomisupply.com\/products\/sigma-818907685-hex-head-pipe-bushing-2x1-5in-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
