Mueller Streamline WB04048 Copper Tee 1 Inch Cxcxc

Product Description

The MUELLER STREAMLINE WB04048 is a 1-inch copper tee fitting configured in a C x C x C (sweat) end pattern, designed for use in pressurized plumbing and hydronic systems. All three ports accept standard copper tubing joined by soldering, making it a reliable choice for branch connections in water distribution lines. Licensed plumbers and pipefitters install this fitting in residential and light commercial applications where a durable, corrosion-resistant branch connection is required. Its all-copper construction ensures compatibility with potable water systems and meets expectations for long-term service life in both hot and cold water lines.

This tee fitting is suited for residential and commercial water supply piping, radiant heating systems, and general plumbing rough-in work. The 1-inch size fits standard Type L and Type M copper tubing and is appropriate for main-line branch-offs in supply and return configurations. Domestic manufacture supports projects with buy-American requirements or specifications that restrict imported fittings on municipal or government work.

Installation Notes

Installation is performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. Shut off the water supply and fully drain the line before cutting and fitting. Clean all mating surfaces with emery cloth and apply appropriate flux before soldering; heat evenly and allow joints to cool fully before restoring pressure. Do not use open flame near insulation or combustible framing without a proper heat shield in place.
