It accepts 1\/2 inch female NPT, 1\/2 inch male NPT, and 1\/2 inch sweat connections, giving installers flexibility across copper and threaded pipe configurations. The dielectric sleeve and seat electrically isolate the two sides of the joint, stopping the electrochemical reaction that degrades fittings over time. At 0.6 pounds, it is a compact, single-piece fitting suited for residential and light commercial plumbing installations. Licensed plumbers and pipefitters are the typical installers for this type of union.\u003c\/p\u003e\n\u003cp\u003eThis dielectric union is used wherever a transition between copper tubing and threaded iron or steel pipe is required. Common applications include connections at water heaters, boilers, and other plumbing equipment where copper supply lines meet steel or galvanized threaded ports. The sweat end accommodates direct solder connection to copper pipe, while the NPT ends thread directly onto iron fittings or equipment nipples. It is appropriate for residential potable water systems and light commercial plumbing where local codes require dielectric isolation at dissimilar-metal joints.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-way connection compatibility: 1\/2 inch FNPT, 1\/2 inch MNPT, and 1\/2 inch sweat\u003c\/li\u003e\n  \u003cli\u003eDielectric isolation prevents galvanic corrosion at dissimilar-metal transitions\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 2.75 inches tall, 1.75 inches wide\u003c\/li\u003e\n  \u003cli\u003eSingle-unit package suitable for individual repair or replacement jobs\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.6 pounds for easy single-hand installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement dielectric union for residential and light commercial plumbing systems requiring 1\/2 inch threaded or sweat connections at dissimilar-metal transitions.\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 International Plumbing Code (IPC). Shut off the water supply and relieve system pressure completely before removing the existing fitting or making new connections. Use thread sealant or PTFE tape on all NPT threads and follow standard soldering practice for the sweat end. Do not over-tighten the union nut, as excessive force can damage the dielectric seat and compromise electrical isolation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 1\/2 inch FNPT, 1\/2 inch MNPT, 1\/2 inch Sweat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnion Type\u003c\/strong\u003e: Dielectric Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 168-003NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699064602930,"sku":"168-003NL","price":23.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/feabb72e653044189cb05a9d0d92462b.jpg?v=1788371884","url":"https:\/\/voomisupply.com\/products\/value-collection-168-003nl-dielectric-union-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
