It connects female iron pipe thread (FIP) on one side to a copper solder joint on the other, preventing electrolytic corrosion and galvanic action at the transition point. Dielectric unions are a code-required fitting in many jurisdictions wherever copper piping meets steel or galvanized pipe. The fitting creates an insulating barrier between the two metals, stopping the electrochemical reaction that accelerates pipe corrosion and eventual joint failure.\u003c\/p\u003e\u003cp\u003eThis union is used in water supply piping where copper lines connect to galvanized steel, black iron, or other ferrous pipe sections. Typical install scenarios include water heater inlet and outlet connections, main service entry transitions, and any point where a copper distribution system interfaces with a threaded steel supply line. The 1\/2-inch size fits standard residential water supply branch lines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrevents electrolysis and galvanic corrosion at dissimilar-metal pipe joints\u003c\/li\u003e\n\u003cli\u003eFemale iron pipe thread x copper solder joint end connections for direct transition fitting\u003c\/li\u003e\n\u003cli\u003e1\/2-inch nominal size suits standard residential branch supply lines\u003c\/li\u003e\n\u003cli\u003eUnion design allows pipe to be disconnected and reconnected without cutting\u003c\/li\u003e\n\u003cli\u003eSold as individual unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation dielectric union for 1\/2-inch female iron pipe thread to copper solder joint transitions in residential and light commercial plumbing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber. Shut off the water supply and relieve system pressure before beginning work. The copper side is soldered using standard sweat-joint technique; the iron pipe side is threaded with appropriate thread sealant or PTFE tape per local code. Local plumbing codes, including the IPC, typically require dielectric unions wherever copper and ferrous piping are joined in a water system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Female Iron Pipe Thread x Copper Solder Joint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 30 per case (sold as each)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.24 pounds (case)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HOMEWERKS WORLDWIDE LLC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 520-01-12-12B-Z\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOMEWERKS WORLDWIDE","offers":[{"title":"Default Title","offer_id":51524067262770,"sku":"520-01-12-12B-Z","price":215.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5eee761034bf4692a4186adb40707550.jpg?v=1785444923","url":"https:\/\/voomisupply.com\/products\/homewerks-520-01-12-12b-z-dielectric-union-0-5-in-fip-x-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
