Soft copper refrigeration tubing is the soft copper tube used in refrigeration or thermoelectric coolers. Refrigeration is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir. Soft copper tubing is widely used as a refrigerant line in HVAC (heating ventilation air conditioning) systems. It is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion  resistance.
