Constructed from malleable iron with a black oxide finish, this bushing is built for use in low-pressure piping systems where a durable, threaded reduction fitting is required. The hex head profile allows for wrench engagement during installation, making tightening and removal straightforward. At a 150 lb pressure rating, it suits standard residential and light commercial piping applications. Licensed plumbers and pipefitters are the typical installers for this class of fitting.\u003c\/p\u003e\n\u003cp\u003eThis bushing fits into pipe systems that require a step-down reduction between nominal 1-1\/2 inch and 1-1\/4 inch threaded pipe. It is commonly used in hydronic heating systems, gas distribution piping, compressed air lines, and general plumbing rough-in work. The MNPT x FNPT configuration means the male thread screws into a larger female-threaded fitting or valve, while the female end accepts a smaller male-threaded pipe or nipple. This fitting is suited for both residential and light commercial installations where malleable iron fittings meet system specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHex head design allows wrench engagement for secure make-up and removal\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and impact resistance in threaded piping systems\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers surface protection in dry or low-moisture environments\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class suits standard residential and light commercial service\u003c\/li\u003e\n  \u003cli\u003eMNPT x FNPT end style for direct threaded connections without additional adapters\u003c\/li\u003e\n  \u003cli\u003eNominal 1-1\/2 x 1-1\/4 inch sizing covers a common reduction step in pipe assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded reduction fitting for use in standard 150 lb malleable iron pipe systems with NPT threaded connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the system type. Shut off and depressurize the piping system fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before make-up. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3383\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1-1\/4 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\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: 818907412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524699586866,"sku":"BLBUSH112114I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89b042a6433f59f3a7393de72ad9a709_0cc2858e-5520-4430-b263-17b0842796d9.jpg?v=1785455684","url":"https:\/\/voomisupply.com\/products\/sigma-818907412-hex-head-pipe-bushing-1-5x1-25-in-mnpt-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
