The union features a 1-inch FNPT (female NPT) inlet on one side and a 1-inch Female C (sweat\/solder) connection on the other, making it suitable for installations where copper tubing meets threaded steel or iron pipe. Constructed from steel, this union provides the mechanical strength needed for residential and light commercial plumbing and HVAC hydronic systems. Licensed plumbers and HVAC technicians install dielectric unions as a code-required measure wherever copper and ferrous piping meet.\u003c\/p\u003e\n\u003cp\u003eThe 1-DUXLC is used in residential and commercial plumbing systems at connection points between copper supply lines and threaded steel or galvanized pipe, such as at water heater inlets and outlets, boiler connections, and hydronic heating system tie-ins. The FNPT x Female C configuration accommodates a direct transition from threaded iron or steel pipe to copper tubing without requiring an adapter. This fitting is suitable for domestic hot and cold water service and hydronic heating applications where galvanic isolation is required by plumbing code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDielectric insert isolates copper from steel or iron piping to stop galvanic corrosion\u003c\/li\u003e\n  \u003cli\u003e1-inch FNPT x Female C connection accommodates threaded-to-sweat transitions\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability for pressure piping applications\u003c\/li\u003e\n  \u003cli\u003eStandard union design allows for future disconnection without cutting pipe\u003c\/li\u003e\n  \u003cli\u003eSuitable for water heater, boiler, and hydronic system connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation dielectric union for residential and commercial plumbing systems requiring a 1-inch FNPT x Female C galvanic isolation fitting.\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 depressurize the system before installation. The Female C (sweat) end requires soldering with appropriate flux and lead-free solder per code; do not apply torch heat directly to the dielectric insert or union body. Apply thread sealant or PTFE tape to the FNPT end before threading onto the mating fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT x Female C (Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: WILKINS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1-DUXLC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILKINS","offers":[{"title":"Default Title","offer_id":51523566993714,"sku":"1-DUXLC","price":33.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9377351205c5b2f27700f16d5d75a038.jpg?v=1785442803","url":"https:\/\/voomisupply.com\/products\/wilkins-1-duxlc-dielectric-union-1-in-fnpt-x-female-c","provider":"Voomi Supply","version":"1.0","type":"link"}
