A tube manufactured to special requirements as to dimensional tolerances, finish and tempers for use in condensers and heat exchangers. These copper Heat Exchanger tubes are generally supplied in straight length in even annealed half hard temper. The copper tubes produced by Tube Tech not only have the tightest tolerances but also have the most consistent dimensions throughout the tube length. The tube surface is clean both inside and outside with no corrosive stains. The copper tubes produced by Tube Tech are compatible to transfer heat in a wide variety of operating conditions and to resist corrosion for the longest period of time possible under the harshest operating conditions.
