The Bykski Metal Rigid Tubing is a chrome plated copper material making it extemely durable. It has a seamless construction, which provides a smooth interior surface. It comes in an angled run that allows you to custom fit bends but cutter either end. 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.
