Mueller Streamline 10056668 Solder Union 2.5 Inch Brass

Product Description

The MUELLER STREAMLINE 10056668 is a 2-1/2 inch nominal brass solder union designed for joining copper tubing in plumbing and hydronic systems. This fitting uses a C (solder cup) end style on both connections, allowing a licensed plumber to sweat the union in-line for future serviceability. Brass construction provides corrosion resistance and reliable performance in wet service environments. The union design allows the line to be broken and reconnected without cutting pipe, making it a standard choice for equipment connections where periodic removal is expected.

This solder union is suited for residential and light commercial plumbing installations, hydronic heating systems, and copper distribution lines where a removable connection point is required. It is domestically produced and appropriate for potable water, heating, and cooling piping applications. Installers typically use this fitting at equipment connections such as water heaters, pumps, boilers, and similar serviceable components.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC standards. Shut off the water supply and relieve system pressure before beginning work. Clean and flux all mating surfaces thoroughly before sweating; overheating brass fittings can damage sealing surfaces. Ensure the union nut is properly seated and hand-tightened before final torque to avoid cross-threading.
