3/16" × 30" Copper-Nickel Brake Line – Pre-Flared, Ready to Install

Upgrade your brake system with a premium copper nickel brake line engineered for lasting performance. This RightQuick 3/16" × 30" tube ships double-flared and fitted with a 3/8-24 inverted-flare nut already in place, turning what once required a specialty flaring tool into a simple cut-to-fit swap you can tackle in minutes.

Crafted from a 90-10 copper-nickel alloy, the line combines copper’s natural flexibility with nickel’s outstanding resistance to salt, moisture, and road chemicals. It dissipates heat more efficiently than traditional steel tubing and exceeds SAE J1047 and FMVSS 106 burst-pressure and whip standards, giving you true OEM-grade safety on every install.

At 30 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 exact length, deburr the cut, slide the nut back into place, and torque to spec—no expensive tools required. Copper-nickel bends up to 65 % easier than steel, so tight chassis curves become a one-person task.

The nickel content also prevents galvanic reactions with stainless or aluminum brake 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.
