3/16" × 38" Copper-Nickel Brake Line – Pre-Flared, Ready to Install

Upgrade corroded steel tubing with a copper-nickel brake line designed for lasting performance and easy installation. This 3/16-inch-diameter, 38-inch RightQuick line ships double-flared with a 3/8-24 inverted-flare fitting already threaded on, so you can replace rusted or damaged lines in minutes without renting a flaring tool.

Crafted from a 90-10 copper-nickel alloy, the tube combines copper’s natural flexibility with nickel’s exceptional resistance to salt, moisture, and road chemicals. It dissipates heat more efficiently during repeated stops and exceeds SAE J1047 and FMVSS 106 burst-pressure and whip standards for true OEM-grade safety.

At 38 inches, this length is ideal for ABS module jumpers, master-to-proportioning-valve runs, or custom street-rod plumbing. Simply route the line, trim to fit, slide the nut back into place, and torque to spec—no specialty tools required.

Copper-nickel bends up to sixty-five percent easier than steel, turning tight chassis curves into a one-person task. The nickel content also prevents galvanic reactions with stainless or aluminum components, protecting every union from hidden corrosion and seized fittings over time.

Backed by the 4LifetimeLines Lifetime Warranty, this copper-nickel brake line lets you install it once and drive with confidence.
