Constructed from malleable iron with a galvanized finish, this bushing is rated for 150 lb service pressure. The hex head profile allows wrench engagement for reliable torque during installation. Plumbers and pipefitters install this fitting in threaded pipe assemblies wherever a concentric size reduction is needed at a junction point in the line.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for residential and commercial plumbing, fire protection, and general industrial piping systems that use standard 150 lb threaded malleable iron fittings. The male NPT by female NPT end configuration makes it a direct-thread reducer, threading into a larger female fitting while accepting a smaller male pipe or fitting on the opposite end. It is commonly installed in water supply lines, low-pressure steam systems, air lines, and similar threaded pipe networks where galvanized iron components are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch FNPT inlet reducing to 1 inch MNPT outlet for concentric pipe size reduction\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides toughness and resistance to mechanical shock\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish adds corrosion resistance for water and outdoor service environments\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating compatible with standard threaded pipe system fittings\u003c\/li\u003e\n  \u003cli\u003eHex head design allows secure wrench engagement during makeup and removal\u003c\/li\u003e\n  \u003cli\u003eFIG 3383 standard profile ensures dimensional interchangeability with comparable fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for 150 lb malleable iron threaded pipe systems using NPT connections.\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 plumbing codes such as the IPC. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply thread sealant or PTFE tape to the male threads before makeup, and tighten to a snug fit using a pipe wrench on the hex head — avoid overtightening, which can crack malleable iron fittings. Inspect threads for damage before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1 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\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: 819907445\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525507252530,"sku":"GALBUSH1121I-LF","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89b042a6433f59f3a7393de72ad9a709_4e8f9e38-7b22-458d-94ad-647392a1ce98.jpg?v=1785475913","url":"https:\/\/voomisupply.com\/products\/sigma-819907445-hex-head-pipe-bushing-1-5x1-in-150lb-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
