Mueller Streamline w04005 Reducing Tee C X C X C 1/4 Inches X 1/4 Inches X 3/8 Inches Wrot Copper Solder Joint Fitting

Product Description

The Mueller Streamline w04005 is a wrot copper reducing tee designed for use in above-ground potable water supply and pressurized plumbing systems. This fitting features a C x C x C (cup by cup by cup) end configuration, with two 1/4 inch ends and one 3/8 inch end, making it the right choice when a branch line of a different diameter needs to be tapped off a main run. The cup ends accept standard copper tubing for soldering, providing a leak-free mechanical joint when properly sweated with appropriate flux and solder. Wrot copper fittings are cold-worked from copper tube, which produces a dense grain structure that delivers reliable strength and long service life in demanding plumbing installations. Mueller Streamline has manufactured copper solder-joint fittings for over 80 years and is widely recognized by plumbers and mechanical contractors as one of the most trusted names in the industry. The w04005 reducing tee meets NSF 61G requirements, confirming it is safe for use in potable water systems. It is also manufactured to multiple ASME standards including B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1, ensuring dimensional accuracy and compatibility with other code-compliant copper fittings. Plumbers, pipefitters, and mechanical contractors rely on this type of reducing tee when routing domestic water lines, hydronic distribution systems, and other copper piping applications where a branch reduction is required. At just 0.04 pounds, the fitting is lightweight and easy to handle during installation. The precision cup ends allow for consistent solder pull-through and uniform joint formation, reducing the chance of voids or cold joints in the finished connection.

• Wrot copper construction provides high density grain structure and long-term durability in pressurized water systems
• C x C x C end connections with 1/4 inch x 1/4 inch x 3/8 inch sizing allow a direct branch reduction off the main copper run
• Meets NSF 61G for potable water safety and manufactured to ASME B16.22 and multiple additional ASME dimensional standards
