This 4 inch x 1 inch bushing features a male 4-inch NPT end and a female 1-inch NPT end, allowing two pipes of different diameters to connect in-line. The hex profile enables wrench engagement for proper torque during installation. Weighing 3.59 pounds, it is a heavy-duty fitting intended for use in commercial and industrial plumbing, HVAC hydronic systems, and gas distribution lines. Licensed plumbers and pipefitters are the primary installers of this type of fitting.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for residential and commercial applications where a large-diameter threaded pipe or valve must transition down to a 1-inch threaded connection. Typical scenarios include reducing main supply lines at equipment connections, boiler piping assemblies, and similar threaded pipe configurations. The black coating makes it appropriate for gas piping as well as water and steam systems where galvanized fittings are not specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHex body profile allows standard pipe wrench or adjustable wrench engagement for secure installation\u003c\/li\u003e\n\u003cli\u003eCast iron construction provides strength and durability in high-pressure threaded pipe assemblies\u003c\/li\u003e\n\u003cli\u003eBlack coating suitable for gas, water, and steam piping applications\u003c\/li\u003e\n\u003cli\u003e4 inch x 1 inch size handles significant diameter reduction in a single fitting\u003c\/li\u003e\n\u003cli\u003eDomestically sourced fitting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for threaded cast iron pipe systems requiring a 4-inch to 1-inch reduction in residential and commercial plumbing, HVAC, and gas distribution applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before making up the joint. Do not over-tighten cast iron fittings, as the material is not ductile and can crack under excessive stress.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 4 inches x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Hex Bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 3.59 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASC ENGINEERED SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 318909009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233704149298,"sku":"0318909009","price":268.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307630688.jpg?v=1780107169","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-318909009-cast-iron-hex-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
