1/4" × 116" Copper-Nickel Brake Line – Pre-Flared, Ready to Install

Replace corroded steel tubing with a copper nickel brake line built for the long haul. This 1/4-inch-diameter, 116-inch RightQuick line is double-flared at both ends and arrives with 7/16-24 and 1/2-20 inverted-flare fittings already threaded on, turning what used to be a specialty-tool job into a straightforward cut-to-fit swap.

Drawn from a 90-10 CuNi alloy, the tube blends copper’s natural flexibility with nickel’s remarkable resistance to salt, moisture, and road chemicals. It lasts far longer than traditional steel, bends smoothly around cross-members by hand, and sheds heat quickly during repeated hard stops. Each run exceeds SAE J1047 and FMVSS 106 burst-pressure and whip requirements, delivering OEM-grade safety on every mile.

At 116 inches, this length bridges master-to-ABS modules, frame-to-axle spans, or custom street-rod plumbing with room to trim for an exact fit. Copper-nickel bends up to sixty-five percent easier than steel, so routing tight chassis curves becomes a one-person task. Nickel in the alloy blocks galvanic reactions with stainless or aluminum components, guarding every union against hidden corrosion.

Like every 4LifetimeLines component, the line is backed by our Lifetime Warranty—install it once and focus on your next project. Need other sizes or flare combinations?
