It accepts 3\/4-inch female NPT, 3\/4-inch male NPT, and 3\/4-inch sweat connections, making it adaptable to copper and threaded iron or steel piping in a single fitting. Weighing 1.18 pounds, this union is sized for residential and light commercial plumbing applications. Licensed plumbers and pipefitters install dielectric unions wherever copper tubing meets ferrous pipe, such as at water heater connections, boiler supply and return lines, and other mixed-metal piping transitions.\u003c\/p\u003e\n\u003cp\u003eThis dielectric union is suited for residential and commercial plumbing installations where copper pipe meets galvanized steel or black iron pipe. Typical applications include water heater inlet and outlet connections, hydronic heating system piping, and general domestic water supply lines. The sweat end accommodates standard 3\/4-inch copper tubing, while the NPT ends accept threaded steel or brass fittings. This fitting is sold as a single unit per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDielectric union design isolates dissimilar metals to prevent galvanic corrosion\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch FNPT, 3\/4-inch MNPT, and 3\/4-inch sweat connection options in one fitting\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions: 1.31 inches length, 1.22 inches width, 1.85 inches height\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for individual repair or replacement jobs\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 3\/4-inch copper tubing and 3\/4-inch NPT threaded pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement dielectric union for 3\/4-inch residential and light commercial plumbing systems using mixed copper and threaded ferrous pipe.\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 before removing any existing fitting. Sweat connections require proper flux application and soldering technique; threaded connections should be sealed with thread sealant or PTFE tape rated for water service. Do not overtighten threaded ends, as the internal dielectric sleeve can be damaged by excessive force.\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: 3\/4 inch FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size (Male NPT)\u003c\/strong\u003e: 3\/4 inch MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSweat Size\u003c\/strong\u003e: 3\/4 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: 1.18 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: 167-004NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708003516722,"sku":"167-004NL","price":21.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf6ca88b7d7d72275977448cabb902cc.jpg?v=1788443326","url":"https:\/\/voomisupply.com\/products\/value-collection-167-004nl-dielectric-union-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
