Mueller Streamline 9107050 Copper Tee 3x3x1/2 in Cxcxc

Product Description

The MUELLER STREAMLINE 9107050 is a reducing copper tee fitting designed for use in residential and commercial plumbing systems. This fitting connects three copper pipe runs in a tee configuration, with two 3-inch run ports and one 1/2-inch branch port, all joined via sweat (solder) connections. The C x C x C end style means all three openings accept copper pipe for soldered joints, making this a standard workhorse fitting for potable water distribution, hydronic heating loops, and general plumbing rough-in. Licensed plumbers and pipefitters install this type of fitting during new construction and retrofit work.

This tee is suited for installations where a main 3-inch copper line requires a reduced 1/2-inch branch takeoff — common in large-diameter domestic water mains, commercial building supply lines, and mechanical room piping. Domestic manufacture supports project specifications that require USA-made components. The 611R series from MUELLER STREAMLINE is a widely recognized designation in the copper fitting trade.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and fully drain the line before cutting and fitting. Clean all pipe ends and fitting sockets thoroughly and apply flux before soldering. Avoid overheating the fitting during the sweat process, as excessive heat can damage the fitting or nearby components.
