Mueller Streamline w04070 Reducing Tee C X C X C 1-1/4 Inches X 1-1/4 Inches X 3/4 Inches Wrot Copper Solder-joint Fitting

Product Description

The Mueller Streamline W04070 is a wrot copper reducing tee designed for soldered copper pipe systems in residential and commercial plumbing applications. This fitting connects three copper pipes using cup-style solder joints, with two 1-1/4 inch ends running inline and one 3/4 inch branch outlet. The C x C x C configuration means all three ports accept standard copper tubing for a clean, leak-free soldered connection. Wrot copper fittings are formed from solid copper stock, giving them a dense grain structure that resists corrosion and holds up under sustained pressure and temperature cycling. This makes them a preferred choice for licensed plumbers and pipefitters working on potable water supply lines, hydronic heating systems, and other pressurized copper piping systems. The reducing tee is used when a main run needs to branch off to a smaller line, such as feeding a 3/4 inch supply to a fixture or sub-loop while maintaining full 1-1/4 inch flow through the main run. Mueller Streamline has manufactured copper solder-joint fittings for over 80 years and is widely trusted in the trade for dimensional accuracy and consistent quality. The W04070 meets NSF 61G standards for use in above-ground potable water supply systems, confirming it is safe for drinking water contact. It also conforms to multiple ASME standards covering copper and bronze fittings, including B16.22 for wrought copper fittings and B16.18 for cast copper alloy fittings. At 0.35 pounds, the fitting is lightweight and easy to handle during installation. Plumbers, pipefitters, and mechanical contractors working on copper pipe systems will find this fitting reliable and code-compliant for a wide range of supply and distribution applications.

• Wrot copper construction provides a dense, corrosion-resistant grain structure suited for pressurized water systems
• C x C x C solder-joint ends on all three ports for a secure, leak-free copper pipe connection
• NSF 61G listed and ASME compliant, making it safe and code-approved for potable water supply applications
