3/16" x 25' Copper-Nickel Brake Line Kits – 2-Pack with Fittings

The 4LifetimeLines Copper-Nickel Brake Line Tubing Coils and Fittings – 2 Kits (3/16″ × 25′) bundle provides two complete brake line solutions crafted for corrosion resistance, durability, and reliable performance. Each kit features premium copper-nickel (CuNi 90/10) alloy brake line tubing and precision SAE inverted-flare fittings, delivering everything technicians need to fabricate or replace brake lines efficiently.

Copper-nickel tubing bends smoothly without kinking and works with standard flaring tools to support secure single and double flares, helping speed installation and improve consistency across jobs. Copper-nickel alloy resists rust, moisture, and environmental wear better than traditional steel lines, making it an ideal choice for vehicles in corrosive climates, coastal regions, and high-use applications. With two full kits included, shops and service centers can stock up for multiple brake jobs without frequent restocking.

Backed by the 4LifetimeLines lifetime warranty, this double-kit bundle offers shop-ready material that helps reduce callbacks, save time, and deliver professional-grade results.

    Pleasantly surprised

    I must admit I was not sure what to expect in quality due to how reasonable the price was, but I was pleasantly surprised from the moment I received my package. First the items were extremely well packaged both outside and the internal packaging. Secondly the quality of the items met all my expectations. I would not hesitate to make another purchase.
