Unions allow sections of copper pipe to be disconnected and reconnected without cutting, making them essential for serviceable connections at water heaters, pumps, and shutoff assemblies. The fitting is machined from copper with an outside diameter of 1-5\/8 inches, consistent with standard 1-1\/2 inch nominal pipe sizing. Licensed plumbers and pipefitters specify copper unions where future access or component replacement is anticipated in the system layout.\u003c\/p\u003e\n\u003cp\u003eThis union is suited for potable water supply lines, hydronic heating loops, and general plumbing distribution systems where a removable, leak-tight joint is required. The C x C end configuration accepts standard 1-1\/2 inch copper tubing soldered with lead-free solder per current plumbing code requirements. It is appropriate for both new construction rough-in and retrofit service work where an existing threaded or soldered connection must be broken and re-established cleanly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch nominal size with C x C sweat end connections for direct copper tubing integration\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance in potable water and hydronic applications\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 1-5\/8 inches matches standard nominal 1-1\/2 inch copper pipe fitment\u003c\/li\u003e\n  \u003cli\u003eUnion design allows future disconnection without cutting pipe, simplifying equipment service\u003c\/li\u003e\n  \u003cli\u003eCompatible with lead-free solder per IPC and local plumbing code requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style replacement or new-installation copper union for 1-1\/2 inch nominal copper pipe systems using sweat (solder) connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local IPC or applicable plumbing codes. Shut off the water supply and depressurize and drain the line fully before cutting or soldering. Use lead-free solder and appropriate flux rated for potable water service when making sweat connections. Allow all joints to cool completely before restoring system pressure and inspecting for leaks.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Copper Fittings\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: HAILIANG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HLG15-657-0295\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HAILIANG","offers":[{"title":"Default Title","offer_id":51306216882482,"sku":"HLG15-657-0295","price":55.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549046.jpg?v=1781286889","url":"https:\/\/voomisupply.com\/products\/hailiang-hlg15-657-0295-copper-union-1-1-2-inch-c-x-c","provider":"Voomi Supply","version":"1.0","type":"link"}
