Elkhart Products COU-14 Copper Coupling with Stop 1/4 in

Product Description

The ELKHART PRODUCTS COU-14 is a 1/4-inch copper coupling with stop, designed for sweat-solder (C x C) connections in refrigeration, HVAC, and plumbing tubing systems. Part of the KLEENFIT product line, it arrives cleaned and bagged to meet cleanliness standards required for refrigeration and ACR applications. The integral stop positions tubing consistently during assembly, ensuring repeatable joint depth and reducing the risk of a misaligned solder joint. At 0.007 pounds, it is a compact fitting suited for tight-space installations where a controlled insertion depth is critical to a leak-free result.

This coupling is used in residential and light commercial HVAC, refrigeration, and plumbing applications wherever 1/4-inch copper tubing must be joined inline. The KLEENFIT designation indicates the fitting is pre-cleaned and bagged at the factory, making it appropriate for ACR tubing assemblies and other applications where contamination control is required before brazing or soldering. It is typically installed by licensed HVAC technicians, refrigeration mechanics, or plumbers working with small-diameter copper lines.

Key Features

• Integral stop ensures consistent tubing insertion depth for repeatable solder joints
• KLEENFIT line: factory-cleaned and bagged to maintain internal cleanliness for ACR and plumbing use
• 1/4-inch C x C sweat-solder connection on both ends
• Copper construction for compatibility with standard copper tubing and solder alloys
• Compact profile at 0.43 x 0.71 x 0.43 inches for use in confined spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch copper tubing systems using C x C sweat-solder joints in HVAC, refrigeration, and plumbing applications.

Installation Notes

Installation should be performed by a qualified HVAC technician, refrigeration mechanic, or licensed plumber. Isolate and recover any refrigerant or shut off the water supply and depressurize the line before cutting or fitting the tubing. Clean and flux mating tube ends per standard soldering or brazing practice before assembly. Local mechanical codes and, where applicable, ASHRAE 15 or IPC requirements should be followed for the specific system type.
