Seamless red copper tube is most often used for supply of hot and cold tap water, and as refrigerant line in HVAC (heating ventilation air conditioning) systems. There are two basic types of copper tubing, soft copper and rigid copper. Copper tube is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance.
The colour of pure copper is near red, so pure copper tube is called red copper tube.
