1/4" × 100" Copper-Nickel Brake Line – Pre-Flared, Ready to Install

Upgrade your next repair with a copper nickel brake line that endures salt, moisture, and everyday road abuse while bending effortlessly by hand. This RightQuick 1/4-inch × 100-inch tube ships double-flared with 7/16-24 and 1/2-20 inverted-flare fittings already in place, turning a job that once required specialty tools into a straightforward cut-to-fit swap.

The 90-10 CuNi alloy blends copper’s flexibility with nickel’s exceptional corrosion resistance, delivering a line that outlasts traditional steel and dissipates heat more efficiently on long downhill pulls or stop-and-go commutes. Manufactured to exceed SAE J1047 and FMVSS 106 burst-pressure and whip standards, it provides OEM-grade safety you can stake your reputation on.

At 100 inches, this length is perfect for master-to-ABS runs, frame-to-axle spans, or custom hot-rod plumbing; trim the line if you need a shorter section, re-slide the nut, and you’re ready for torque. Copper nickel bends up to sixty-five percent easier than steel, so snaking through cross-members and tight chassis curves is a one-person task. Nickel content also prevents galvanic reactions with stainless or aluminum components in modern braking systems, safeguarding every union from hidden corrosion.

Like every component in the 4LifetimeLines catalog, this brake line carries our Lifetime Warranty, giving you the confidence to install it once and move on to the next project.
