Built from malleable iron with a galvanized finish, this bushing handles standard 150 lb pressure-rated piping systems. The hex head profile allows for wrench installation, providing solid torque control during assembly. It is a common fitting for HVAC, plumbing, and fire protection piping where pipe size transitions are required. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in residential and commercial piping systems where a 4-inch line must transition to a 2-inch branch or connection point. Typical applications include water supply lines, gas distribution piping, and steam systems rated at 150 lb. The galvanized coating provides corrosion resistance in wet or outdoor-exposed environments. FIG 3383 references the standard hex head bushing pattern used across the industry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 4-inch FNPT to 2-inch MNPT for straightforward pipe size transitions\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating suitable for standard piping service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides durability and impact resistance\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish resists corrosion in wet or exposed installations\u003c\/li\u003e\n  \u003cli\u003eHex head design allows wrench engagement for secure, leak-free make-up\u003c\/li\u003e\n  \u003cli\u003eFIG 3383 pattern for industry-standard fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement 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 is performed by licensed plumbers or pipefitters following applicable IPC or IFGC requirements depending on the service. Shut off the water, gas, or steam supply and depressurize the line fully before disassembly or fitting installation. Apply thread sealant or PTFE tape to the male threads before makeup. Tighten with a pipe wrench to the hex flats — do not overtighten to the point of cracking the fitting body.\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 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: 819908898\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524509073714,"sku":"GALBUSH42I-LF","price":27.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89b042a6433f59f3a7393de72ad9a709_7857e897-d0df-4cdb-972c-4f333dce255e.jpg?v=1785450305","url":"https:\/\/voomisupply.com\/products\/sigma-819908898-hex-head-pipe-bushing-2x4-in-150lb-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
