Standard Air Conditioner Connecting Pipes

Standard air conditioner connecting pipes (or refrigerant piping) are pre-insulated copper tubes used to link indoor and outdoor units in split HVAC systems. They facilitate the circulation of refrigerant (e.g., R32, R410A) between components, ensuring efficient heat exchange.

Key Features:

1. Material: Made of deoxidized copper (Cu-DHP) for corrosion resistance and high thermal conductivity.

2. Insulation: Foamed polyethylene (PE) or rubber sleeves prevent condensation and thermal loss.

3. Sizes: Common diameters include 1/4", 3/8", 1/2", 5/8",3/4",7/8" (metric: 6.35mm, 9.52mm, 12.7mm, 15.88mm,19.05mm,22.22mm,).

4. Flaring: Ends are flared (45°) to ensure leak-proof brazed or threaded connections.

Applications:

• Split AC systems (residential/commercial)

• Heat pumps and VRV/VRF systems
