Mueller Streamline 10056680 Solder Union 3 Inch Brass

Product Description

The MUELLER STREAMLINE 10056680 is a 3-inch nominal solder union designed for copper-to-copper pipe connections in plumbing and mechanical systems. This brass union uses a C end style, meaning both ends accept standard solder (sweat) connections. It allows sections of copper piping to be joined and later disconnected without cutting the line, making it a practical fitting for serviceable runs in residential and commercial installations. The brass construction provides solid corrosion resistance in water service and hydronic applications. Licensed plumbers and pipefitters are the typical installers for this type of union fitting.

This solder union is suited for use in domestic water supply, hydronic heating, and general plumbing distribution systems where a removable joint is needed at a 3-inch pipe location. The C end style is compatible with standard copper tubing of the corresponding nominal size. Its domestic designation indicates it meets requirements for use in potable water and interior plumbing systems, making it appropriate for both new construction and retrofit work.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off and drain the water supply completely before cutting into any existing line. Clean and flux all mating surfaces thoroughly before applying heat to ensure a leak-free solder joint. Allow all joints to cool fully before restoring system pressure and testing for leaks.
