Unions allow a section of copper pipe to be disconnected and reconnected without cutting, making them essential for equipment isolation, service access, and future repairs. Constructed from copper, this fitting is sized at 2 inches with an OD of 2-1\/8 inches. It is installed by licensed plumbers working on residential and commercial water distribution, hydronic heating, and mechanical piping systems where serviceability is a design requirement.\u003c\/p\u003e\u003cp\u003eThis union is suited for wet plumbing applications where copper-to-copper sweat joints are the specified connection method. Typical installations include supply and return lines at water heaters, boilers, pressure-reducing valves, strainers, and other serviceable components where the ability to break and remake a joint in-line adds value. The C x C end configuration requires standard copper tubing prep and lead-free solder or braze alloy per applicable code.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eC x C (sweat) end connections for standard copper tube integration\u003c\/li\u003e\n\u003cli\u003eFull 2-inch nominal size accommodates high-flow residential and light commercial applications\u003c\/li\u003e\n\u003cli\u003eOD size of 2-1\/8 inches for dimensional reference during layout and rough-in\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance in potable water and hydronic systems\u003c\/li\u003e\n\u003cli\u003eUnion design allows in-line disconnection without cutting pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-use fitting for 2-inch copper plumbing systems using sweat-joint (C x C) connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber following applicable IPC or local plumbing code requirements.
