Copper Joint

Category Overview

The Copper Joint category covers the copper connection fittings that are critically important for the correct operation of VRF (Variable Refrigerant Flow) central air conditioning systems. These specially shaped copper parts act as the main distributor (refnet) that ensures the refrigerant is distributed evenly to the indoor units. A copper joint, when selected incorrectly, can reduce the efficiency of the entire system and also lead to vibration, noise and leakage problems; for this reason, brand, diameter and capacity compatibility are of great importance. At Yedepa.com, we have gathered under one roof the original-quality VRF copper Y joint types needed by professional air conditioning technicians and service engineers.

Products You Can Find in This Category

Our category contains copper Y joint models manufactured specifically for GREE and Daikin compatible central air conditioning systems, sized according to different capacities. Choosing the appropriate reference according to the capacity calculation of your piping line is very important for maintaining system performance. The main products currently in our stock are:

• GREE - Daikin Central Air Conditioner VRF Copper Y Joint - FQ02 (for low-capacity lines)
• GREE - Daikin Central Air Conditioner VRF Copper Y Joint - FQ03 (for medium-capacity branches)
• GREE - Daikin Central Air Conditioner VRF Copper Y Joint - FQ04 (for high-capacity distribution points)
• Additional copper joint options for different diameters and capacities

The FQ02, FQ03 and FQ04 numbers in the product codes represent the total capacity range the joint can support; choosing the correct code is the first condition for the system to run trouble-free for years.

Selection Criteria and Tips

When choosing a copper joint, looking at the brand alone is not enough. You should calculate the total BTU or kW value of the indoor units on your line and decide on the appropriate capacity level, such as FQ02, FQ03 or FQ04. In addition, the inlet and outlet diameters must be compatible with your existing copper tube lines so that the brazing operation can be completed without problems. Since the copper is exposed to high temperatures during joint installation, nitrogen purging prevents oxide formation inside and extends compressor life. Finally, choosing original or original-equivalent quality parts is the safest way to prevent leaks, vibration and loss of warranty.
