The external male NPT thread is sized at 1-1\/4 inches and the internal female NPT thread is sized at 3\/4 inches, allowing a direct transition between two pipe sizes within a threaded piping system. Constructed from malleable iron with a galvanized finish, this bushing carries a 150 lb pressure rating. It is a widely used fitting in plumbing, fire protection, and mechanical piping systems where a threaded pipe size reduction is required.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for residential and commercial plumbing, HVAC hydronic piping, and industrial pipe systems where a threaded reduction is needed at a branch, valve, or equipment connection. The hex head profile allows installation and removal with a standard pipe wrench or open-end wrench, which is useful in tight spaces where a hex fitting provides a more reliable grip than a flush-pattern bushing. The galvanized coating helps resist corrosion in typical wet service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch MNPT outer thread reduces to 3\/4 inch FNPT inner thread\u003c\/li\u003e\n  \u003cli\u003eHex head profile allows wrench engagement for reliable installation and removal\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure-rated malleable iron construction\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish provides corrosion resistance in wet service conditions\u003c\/li\u003e\n  \u003cli\u003eFIG 3383 standard configuration for broad cross-reference compatibility\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 150 lb malleable iron threaded piping 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 local codes and the International Plumbing Code. Shut off 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. Do not over-tighten, as excessive torque can crack malleable iron fittings.\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\/4 x 3\/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: 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: 819907049\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525063967026,"sku":"GALBUSH11434I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89b042a6433f59f3a7393de72ad9a709_74881754-f376-4f2b-9d33-9ab9bc69d5b5.jpg?v=1785463563","url":"https:\/\/voomisupply.com\/products\/sigma-819907049-hex-head-pipe-bushing-1-1-4x3-4-in-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
