Directedair da03r-08x07 Reducing Coupling 7/8 X 3/4 Copper

Product Description

The DIRECTEDAIR da03r-08x07 is a copper reducing coupling fitting designed to connect two copper lines of different diameters in refrigeration, HVAC, and plumbing applications. It transitions from a 7/8 inch connection on one end to a 3/4 inch connection on the other, both in copper. The full copper construction provides reliable corrosion resistance and thermal conductivity suited to refrigerant line sets, ACR tubing, and similar trade applications. HVAC technicians and plumbers install this fitting during system assembly, line set routing, or service work where a diameter reduction is required between two copper sections.

This reducing coupling is commonly used in residential and light commercial HVAC systems, refrigeration line sets, and copper plumbing installations where a controlled diameter transition is needed. It is appropriate for sweat or braze connections depending on the application and local code requirements. The fitting is manufactured to industry standards for both dimensional accuracy and material composition, making it a direct fit in standard copper tube work.

Key Features

• Transitions 7/8 inch copper to 3/4 inch copper in a single fitting
• Full copper construction for corrosion resistance and thermal compatibility
• Manufactured to industry dimensional and material composition standards
• Suitable for refrigerant line sets, ACR tubing, and copper plumbing applications
• Accepts sweat or braze joining methods per application requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper tube systems requiring a 7/8 inch to 3/4 inch reducing connection.

Installation Notes

This fitting is typically installed by licensed HVAC technicians or journeyman plumbers. Recover and isolate any refrigerant or shut off fluid supply before cutting into an existing line. Use appropriate flux and solder or brazing alloy per ASHRAE, IFGC, or IPC guidelines for the specific application. Do not over-heat the fitting during brazing, as excessive heat can affect material integrity.
