Mueller Industries, Inc. STREAMLINE W 04058 Copper Reducing Tee

Copper reducing tee for potable water systems

This Mueller Industries Streamline W 04058 copper reducing tee connects three copper tubes of different sizes in a potable water installation. It is designed for professional plumbers and DIY installers who need a reliable sweat fitting to join 1 in, 3/4 in and 1/2 in nominal copper tubing. The wrot copper construction provides corrosion resistance suitable for drinking water supply lines.

Three cup connections

The fitting features cup connections on all three sides sized for 1 in, 3/4 in and 1/2 in nominal copper tube sizes with corresponding outer diameters of 1 1/8 in and 7/8 in for the larger ends. This specific reducing tee configuration determines whether the part matches the pipe layout, as the centre stop is not applicable and each branch accepts a different tube diameter for sweat soldering.

Wrot copper material handles normal supply pressures

The wrot copper body withstands typical residential water pressures and temperatures found in potable systems without deformation or noise under normal flow conditions. Copper's thermal conductivity allows the joint to heat evenly during soldering, while the smooth interior surfaces minimise turbulence and pressure drop once installed. No external power or moving parts are involved.
