Elkhart Products COU-2 Copper Coupling with Stop 2 Inch

Product Description

The ELKHART PRODUCTS COU-2 is a copper coupling with stop designed for soldered sweat connections in residential and commercial plumbing systems. Part of the KLEENFIT product line, this fitting arrives cleaned and bagged to maintain surface integrity and reduce prep time at the point of installation. The 2-inch x 2-inch copper-to-copper (C x C) configuration accepts standard Type L and Type M copper tubing. At 0.391 pounds, the fitting is lightweight and easy to handle in tight spaces. The internal stop ensures consistent tube seating depth, which is critical for achieving a reliable, leak-free solder joint.

This coupling is suited for potable water supply lines, hydronic heating distribution piping, and general-purpose copper pipe runs in both residential and light commercial applications. Licensed plumbers and pipefitters will find this fitting appropriate for in-wall, under-slab, and mechanical-room installations where a full-length repair or extension splice is required on 2-inch copper lines.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and fully depressurize and drain the line before cutting or soldering. Clean pipe ends and fitting sockets thoroughly with emery cloth and flux before applying heat. Avoid overheating the fitting, as excessive heat can damage the internal stop and compromise joint integrity.
