It features a 1\/2-inch female NPT (FNPT) thread on one end and a 1\/2-inch sweat (solder) connection on the other, making it suitable for transitioning between copper and steel or iron pipe runs. The dielectric insert electrically isolates the two pipe sections, stopping the electrochemical reaction that degrades metal fittings over time. Licensed plumbers and pipefitters install this fitting during new construction and retrofit work where code requires galvanic separation at dissimilar-metal joints.\u003c\/p\u003e\n\u003cp\u003eThis dielectric union is used in residential and light commercial plumbing systems wherever copper tubing meets threaded steel or galvanized pipe. Common install points include water heater connections, boiler supply and return lines, and service entry points. The sweat end accepts standard 1\/2-inch copper tubing, and the threaded end connects to 1\/2-inch NPT male fittings. The fitting is packaged individually and suited for single-unit repair or replacement jobs as well as multi-unit service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDielectric insert isolates dissimilar metals to prevent galvanic corrosion\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch FNPT thread end accepts standard male NPT fittings\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch sweat end compatible with standard copper tubing\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at approximately 1.85 inches tall and 1.31 inches in length\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.46 pounds for easy single-hand positioning during install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install fitting for 1\/2-inch plumbing connections requiring a threaded-to-sweat dielectric transition in residential and light commercial systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and relieve system pressure before disassembly. The sweat end requires standard soldering tools and lead-free solder per applicable code requirements. Do not over-torque the threaded connection, and inspect the dielectric sleeve for proper seating before pressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnion Type\u003c\/strong\u003e: Dielectric Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSweat Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 165-103NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700673937714,"sku":"165-103NL","price":34.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a17f75e02f189249f126dfd4564f8b84.jpg?v=1788393619","url":"https:\/\/voomisupply.com\/products\/value-collection-165-103nl-dielectric-union-1-2-fnpt-x-sweat","provider":"Voomi Supply","version":"1.0","type":"link"}
