Mueller Streamline DWVCOUP2 Dwv Coupling 2 in C X C

Product Description

The MUELLER STREAMLINE DWVCOUP2 is a wrot copper drain, waste, and vent (DWV) coupling sized at 2 inches with a cup-by-cup (C x C) end configuration. It joins two sections of 2-inch copper DWV pipe using standard soldered sweat connections. Wrot copper construction provides consistent wall thickness, clean internal surfaces, and reliable joint strength. This fitting is installed by licensed plumbers during new construction and remodel work on residential and light commercial drain and vent systems.

This coupling is used in DWV piping systems where a straight, in-line connection is required between two lengths of 2-inch copper pipe. Common applications include horizontal drain runs, vertical stack connections, and vent piping above the flood level rim. The C x C socket design accepts standard 2-inch copper tube for soldered assembly per applicable plumbing codes.

Key Features

• Wrot copper construction for uniform wall thickness and smooth interior bore
• Cup-by-cup (C x C) end connections accept standard 2-inch copper DWV tube
• Soldered sweat joint assembly compatible with lead-free solder per code requirements
• Straight coupling design for in-line pipe connections in drain, waste, and vent systems
• No center stop, allowing full engagement for repair or replacement cuts

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 2-inch copper DWV piping systems assembled per ASTM B306 tube specifications.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and drain the affected lines before cutting into any existing piping. Clean all pipe ends and fitting sockets with emery cloth and apply flux before soldering with lead-free solder. Inspect joints for full penetration and allow adequate cool-down time before pressure testing or restoring flow.
