Raceworks 600 Series Hard Line is extruded from lightweight, seamless aluminium tube. It is available in three different sizes, and two different finishes (Raw or Anodised in Black). If using the Black hard line, we recommend using a tube bender such as our RWT-015, to minimise flaking of the black coating on the bends. Should this happen, it has no effect on the integrity and corrosion resistance of the aluminium line. We also have a tube straightener available, RWT-014.
