Copper Nickel Line 25' Roll Various Sizes

Copper Nickel Line

Available in CN3, CN4, CN5 & CN6

Replace rusted, damaged, or leaking automotive lines with copper nickel line that’s easier to work with than traditional steel line. Copper nickel bends easier, flares cleaner, and resists rust and corrosion, making it a great choice when you’re repairing brake, fuel, or custom fluid lines.

Whether you’re fixing a rusted section, replacing old factory line, or building a custom route, copper nickel line gives you a cleaner installation and better long-term corrosion resistance — especially in areas exposed to moisture, road salt, and harsh weather.
