Elkhart Products COU-34X14 Copper Reducing Coupling

Product Description

The ELKHART PRODUCTS COU-34X14 is a copper reducing coupling designed to connect a 3/4-inch line to a 1/4-inch line in plumbing and HVAC refrigerant piping systems. The fitting is cleaned and bagged at the factory, making it ready for use in systems where contamination control matters. This coupling is a standard sweat-fit component installed by licensed plumbers and HVAC technicians working on copper tubing runs in both new construction and service applications.

This coupling is suited for residential and light commercial plumbing, hydronic, and refrigeration piping where a reduction from 3/4 inch to 1/4 inch is required. The cleaned and bagged packaging helps maintain the internal cleanliness of the fitting until installation, which is particularly important in refrigerant and medical gas applications. It is a common component in repair and retrofit work where tube sizes change within a run.

Key Features

• Reduces from 3/4 inch to 1/4 inch copper tubing in a single fitting
• Cleaned and bagged for contamination-controlled applications
• Copper construction for corrosion resistance and reliable soldered joints
• Compatible with standard sweat (solder) joining methods
• Factory cleaning supports use in refrigerant and potable water systems

Compatibility

Designed as an OEM-style sweat-fit copper reducing coupling for use with standard 3/4-inch and 1/4-inch copper tubing in plumbing and HVAC refrigerant piping systems.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician following applicable IPC or IFGC guidelines and local code requirements. Shut off the water supply or recover refrigerant from the system before cutting into any existing line. Use appropriate flux, solder, and a torch rated for copper sweat connections. Avoid contaminating the cleaned interior of the fitting before joining.
