Mueller Streamline w07422 45 Degree Elbow Fitting Cup X Cup 2 Inches Dwv Copper Solder Joint

Product Description

The Mueller Streamline W07422 is a 45-degree elbow copper solder-joint fitting designed for drain, waste, and vent (DWV) plumbing applications. Built from wrot copper, this fitting delivers reliable performance in non-pressurized sanitary systems where consistent flow direction changes are required. The 45-degree angle allows plumbers and pipefitters to redirect piping runs smoothly, reducing turbulence and maintaining proper drainage slope in residential, commercial, and light industrial installations.

This fitting uses a cup by cup (C x C) connection on both ends, meaning each end accepts a standard copper pipe for soldering. The 2-inch end size is a common diameter found throughout DWV roughing work, making this elbow a go-to component for waste line offsets, drain stack transitions, and vent piping layouts. The solder cup design provides a secure, leak-resistant joint when properly cleaned, fluxed, and soldered according to standard trade practices.

Wrot copper construction means this fitting is formed by working the metal rather than casting, which results in a denser grain structure and tighter dimensional tolerances. Mueller Streamline manufactures this fitting to meet ASME B16.23 and ASME B16.29 standards, ensuring compatibility with industry-accepted piping systems. Wrot copper fittings in this line also meet NSF 61G requirements, confirming material safety for use in sanitary plumbing systems. The fitting weighs 0.33 pounds, making it easy to handle during overhead or confined-space installations. Plumbers working on new construction, remodel drain systems, or DWV repair projects will find this elbow straightforward to install with standard copper soldering tools and techniques.

• 45-degree elbow provides smooth directional change for DWV drain and vent piping runs
• Wrot copper construction meets ASME B16.23 and B16.29 standards with NSF 61G compliance
• Cup by cup solder-joint ends accept 2-inch copper pipe for secure, permanent connections
