It features a 1-inch female NPT thread, a 1-inch male NPT thread, and a 1-inch sweat (solder) end, offering multiple connection options in a single fitting. Licensed plumbers and pipefitters install this union during water heater connections, boiler piping, and similar applications where copper and steel or iron pipes meet. The dielectric barrier built into the union interrupts electrical continuity between dissimilar metals, extending the service life of connected components.\u003c\/p\u003e\n\u003cp\u003eThis dielectric union is used in residential and light commercial plumbing systems wherever copper tubing meets threaded iron or steel pipe. Typical installation scenarios include water heater inlet and outlet connections, hydronic heating systems, and potable water supply lines. The combination of sweat, FNPT, and MNPT ends provides flexibility for connecting into existing threaded systems or sweated copper runs without additional adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDielectric barrier prevents galvanic corrosion between dissimilar metals\u003c\/li\u003e\n  \u003cli\u003eThree-way connection: 1-inch FNPT, 1-inch MNPT, and 1-inch sweat ends\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 1.85 inches tall and 1.31 inches in length\u003c\/li\u003e\n  \u003cli\u003eSingle-piece union design allows disconnection without cutting pipe\u003c\/li\u003e\n  \u003cli\u003eSuitable for water heater and boiler connection points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement dielectric union for 1-inch residential and light commercial plumbing connections where threaded and sweat pipe ends meet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off the water supply and relieve system pressure completely before disassembling existing unions or making new connections. When making the sweat connection, protect the dielectric insert from excessive heat by applying a wet rag or heat shield, as the non-metallic dielectric material can be damaged by torch temperatures used during soldering. Ensure threaded connections are made with appropriate thread sealant rated for potable water service.\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 (Female NPT)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size (Male NPT)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSweat Size\u003c\/strong\u003e: 1 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: 1.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 165-105NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717279121714,"sku":"165-105NL","price":43.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73f239e25caf231d85cf7b4a5a0d976a.jpg?v=1788537721","url":"https:\/\/voomisupply.com\/products\/value-collection-165-105nl-dielectric-union-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
