It connects female iron pipe (FIP) to female brass pipe (FBP) ends in a 1\/2-inch size. This type of fitting is a standard component in residential and light commercial plumbing systems wherever steel or iron pipe meets copper or brass pipe. Licensed plumbers and pipefitters install dielectric unions as a code-required safeguard against electrolytic corrosion that can degrade pipe joints over time.\u003c\/p\u003e\n\u003cp\u003eThis fitting is commonly used in water heater connections, boiler supply and return lines, and other plumbing applications where ferrous and non-ferrous piping materials meet. The FIP x FBP configuration makes it suitable for threaded pipe installations in both new construction and retrofit service work. At 1\/2 inch, it fits the most common branch and service line sizes found in residential systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDielectric design isolates dissimilar metals to stop galvanic corrosion at pipe joints\u003c\/li\u003e\n  \u003cli\u003eFIP x FBP threaded ends for connection between iron and brass threaded pipe\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch size fits standard residential and light commercial plumbing branch lines\u003c\/li\u003e\n  \u003cli\u003eUnion-style body allows removal and reinstallation without cutting pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation dielectric union for 1\/2-inch threaded plumbing systems where iron or steel pipe connects to copper or brass pipe fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDielectric unions are installed by licensed plumbers in accordance with the International Plumbing Code (IPC) and local amendments. Shut off the water supply and relieve system pressure before removing or installing any union fitting. Use appropriate thread sealant or PTFE tape on all threaded connections. Do not overtighten threaded ends, as this can crack the internal dielectric sleeve and defeat the isolation function.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FIP x FBP (Female Iron Pipe x Female Brass Pipe)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC Code\u003c\/strong\u003e: 082647025592\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: LEGEND VALVE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DUN-EA03\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51233191592242,"sku":"DUN-EA03","price":23.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307611849.jpg?v=1780093711","url":"https:\/\/voomisupply.com\/products\/legend-valve-dun-ea03-dielectric-union-fip-x-fbp-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
