Mueller Streamline w04067 Reducing Tee C X C X C 1/2 X 1/2 X 1 Inch Wrot Copper Solder Fitting

Product Description

The Mueller Streamline W04067 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 (cup by cup by cup) female solder joint configuration. The two run ends accept 1/2 inch copper tubing, while the branch outlet accepts 1 inch copper tubing. This configuration allows plumbers and pipefitters to reduce or split flow from a 1 inch main line down to a 1/2 inch branch, or to combine 1/2 inch lines into a 1 inch run depending on system layout.

Wrot copper is a wrought, work-hardened material known for its dense grain structure, which contributes to reliable pressure ratings and long service life. This fitting is manufactured to meet or exceed ASME B16.22 standards for wrought copper and copper alloy solder-joint pressure fittings, along with ASME B16.15, B16.18, B16.24, B16.50, and B1.20.1. It also meets NSF 61G requirements, confirming suitability for potable water contact. These certifications are commonly required on commercial, residential, and light industrial plumbing projects where code compliance is mandatory.

Mueller Streamline has been a trusted name in copper solder-joint fittings for over 80 years. Plumbers, pipefitters, and mechanical contractors rely on Streamline fittings for consistent dimensions, smooth cup interiors that promote uniform solder flow, and tight tolerances that reduce the risk of leaks. The W04067 reducing tee weighs 0.36 pounds and is a practical, code-compliant solution for copper pipe distribution systems in new construction and retrofit applications alike.

• Wrot copper construction with dense grain structure for reliable long-term performance in pressurized water systems
• C x C x C solder joint ends: two 1/2 inch run connections and one 1 inch branch connection for flow splitting or reducing
