Constructed from malleable iron with a galvanized finish, this bushing is rated for 150 lb service. The hex head profile allows a wrench to seat the fitting securely without marring adjacent components. Plumbers and pipefitters install this type of bushing when transitioning between nominal pipe sizes in threaded iron piping systems, making it a common fitting in both new construction and retrofit work.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in residential and light commercial threaded pipe assemblies, including water distribution, steam, and general mechanical piping systems. The MNPT x FNPT end configuration allows it to thread directly into a larger female-threaded fitting or valve while accepting a smaller male-threaded pipe or nipple on the outlet side. The galvanized coating provides corrosion resistance in wet and moderately corrosive environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch MNPT outlet x 1-1\/2 inch FNPT inlet — reduces one pipe size in a threaded assembly\u003c\/li\u003e\n\u003cli\u003e150 lb pressure rating suitable for standard iron pipe service\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction for strength and thread integrity\u003c\/li\u003e\n\u003cli\u003eGalvanized finish for corrosion resistance in wet service conditions\u003c\/li\u003e\n\u003cli\u003eHex head design allows positive wrench engagement during installation\u003c\/li\u003e\n\u003cli\u003eFIG 3383 pattern — a widely recognized standard bushing configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard fitting for 1-1\/4 inch by 1-1\/2 inch threaded iron pipe systems rated at 150 lb.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLicensed plumbers and pipefitters typically install threaded iron bushings using pipe wrenches and approved thread sealant or PTFE tape applied to the male threads. Shut off and depressurize the system completely before disassembling any threaded fitting. Follow local plumbing codes and IFGC or IPC requirements for the specific application. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/4 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: Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3383\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 819907411\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51523375399218,"sku":"GALBUSH112114I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89b042a6433f59f3a7393de72ad9a709.jpg?v=1785441148","url":"https:\/\/voomisupply.com\/products\/sigma-819907411-hex-head-pipe-bushing-1-1-4-x-1-1-2-in-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
