Actually the "cool flex" product is a corrugated copper - with different finishes - from chrome to various colors. Advantage of the "corrugated" copper is 3 linear feet of copper is used to make 1 linear foot of the corrugated material (approx) with greater heat dissipation. At the time I bought it I was replacing old rubber hoses and was going with ss tube - until I came across the cool flex.
