Mueller Streamline DWVCOUP2112 Dwv Coupling 2-1/2 in

Product Description

The MUELLER STREAMLINE DWVCOUP2112 is a wrot copper DWV coupling designed for drain, waste, and vent piping systems. It features a cup-by-cup (C x C) end configuration, allowing it to be soldered directly to copper pipe on both ends. At 2-1/2 inches, this fitting is sized for mid-range DWV runs commonly found in residential and light commercial plumbing. Licensed plumbers install this fitting as part of gravity-fed drainage systems where leak-free, durable joints are required. Wrot copper construction offers consistent wall thickness and a clean surface finish that promotes reliable solder joints.

This coupling is used in copper DWV systems for connecting two lengths of 2-1/2-inch copper pipe in a straight run. Typical applications include branch drains, vertical stacks, and horizontal waste lines within residential homes, multi-family buildings, and light commercial facilities. The C x C end configuration is compatible with standard sweat-solder installation methods used throughout the plumbing trade.

Key Features

• Wrot copper construction provides consistent wall thickness and smooth interior surface
• Cup-by-cup (C x C) ends accept standard sweat-solder connections on both sides
• 2-1/2-inch nominal size fits mid-range DWV piping runs
• Designed for gravity-fed drain, waste, and vent applications
• No center stop, allowing pipe to be inserted through for repair coupling use

Compatibility

Designed as an OEM-style replacement and standard-fit coupling for 2-1/2-inch copper DWV piping systems installed to ASTM and applicable plumbing code standards.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code and the International Plumbing Code (IPC). Shut off the water supply and drain the affected lines before cutting into existing pipe. Clean and flux all mating surfaces thoroughly before applying solder to ensure a sound, leak-free joint. Avoid overheating the fitting during soldering, as excessive heat can compromise the integrity of the copper.
