Mueller Streamline W 04033cb Copper Reducing Tee 3/4x3/4x1/2

Product Description

The MUELLER STREAMLINE w 04033cb is a copper reducing tee fitting designed for sweat (solder) connections in both residential and industrial piping systems. Configured as a female soldered x female soldered x female soldered (CxCxC) connection, this fitting reduces the branch outlet from 3/4 inches to 1/2 inch while maintaining full 3/4-inch flow on the run. It meets ASME B16.22 dimensional standards and is manufactured from copper, making it compatible with standard plumbing and hydronic applications. The fitting is cleaned and polished for reliable, flux-ready soldering and is backed by a 50-year manufacturer warranty.

This fitting is suited for residential plumbing, light commercial, and industrial piping installations where a branch takeoff at a reduced size is required. Common applications include domestic water distribution, radiant heating supply and return lines, and in-wall rough-in work. The KLEENFIT cleaning process makes it appropriate for use in medical facilities, food processing plants, clean room environments, and research labs where oil- and grease-free fittings are required. A licensed plumber typically installs this fitting during new construction or remodel work.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable edition of the IPC or local plumbing code. Shut off and fully drain the water supply line before cutting or soldering. Clean all tube ends and fitting sockets with emery cloth and apply flux prior to soldering. Do not apply heat directly to finished walls or combustible materials — use a heat shield and keep a fire extinguisher accessible during torch work.
