The Bykski Metal Rigid Tubing is an electroplated brass material making it extemely hard. It has a seamless construction, which provides a smooth interior surface. It comes in a straight run that has a strong corrosion resistance. This style tube is not meant to be bent. We found this tube can be used with great effectiveness as a delivery system for your coolant when using straight runs for your hard tubing. The added metal in your system can't hurt bringing temperatures down in transition between components. By absorbing heat from the coolant the tube can dissipate this heat easily with any kind of average internal airflow in your chassis.
