Mueller Streamline w04087 Wrot Copper Reducing Tee C X C X C 1-1/2 Inches X 1-1/2 Inches X 3/4 Inches

Product Description

The Mueller Streamline W04087 is a wrot copper reducing tee fitting designed for use in above-ground potable water supply and pressurized plumbing systems. This fitting features a C x C x C connection configuration, meaning all three ports accept standard cup-style female solder connections. The run measures 1-1/2 inches on both ends, while the branch outlet steps down to 3/4 inches, making it ideal for splitting flow to a smaller line without requiring an additional bushing or adapter. Plumbers and pipefitters rely on this type of reducing tee when branching off a main supply line to serve a fixture, appliance, or secondary distribution line at a reduced diameter. Mueller Streamline has been manufacturing precision solder-joint copper fittings for over 80 years and is one of the most trusted names in the trade. The W04087 is manufactured from high-grade wrot copper, which offers excellent corrosion resistance, long service life, and superior strength compared to cast fittings. Wrot copper fittings are cold-worked rather than cast, resulting in a denser grain structure and tighter dimensional tolerances. This matters on the job site because consistent dimensions mean cleaner, faster solder joints with less rework. The fitting meets NSF 61G certification requirements, confirming it is safe for use in systems that carry drinking water. It also conforms to multiple ASME standards including B16.22, which governs wrought copper and copper alloy solder-joint pressure fittings. At 0.47 pounds, the W04087 is lightweight and easy to handle in tight spaces. Whether roughing in a new system or retrofitting an existing one, this reducing tee delivers the dimensional accuracy and material quality that professional plumbers demand on commercial and residential jobs alike.

• Wrot copper construction provides a dense grain structure and tight dimensional tolerances for reliable solder joints
• C x C x C configuration with 1-1/2 inches run and 3/4 inches branch outlet for common reducing branch applications
• NSF 61G certified and meets ASME B16.22 and multiple additional ASME standards for potable water safety and pressure system compliance
