3/16" × 46" Copper-Nickel Brake Line – Pre-Flared, Ready to Install

Solve rust problems for good with a copper nickel brake line that bends easily by hand yet stands up to salt, moisture, and road chemicals. This RightQuick tube measures 3/16 inch in diameter and 46 inches in length, and it arrives double-flared with an M10 × 1.0 inverted flare on one end and a 3/8-24 inverted flare on the other, so swapping corroded steel lines becomes a fast cut-to-fit job instead of a fight with specialty tools.

Drawn from a 90-10 CuNi alloy, the line marries copper’s flexibility with nickel’s corrosion resistance and superior heat dissipation. It exceeds SAE J1047 and FMVSS 106 burst-pressure and whip standards, so you get OEM-grade safety whether you’re daily-driving or tracking a project truck. Copper nickel bends up to sixty-five percent easier than steel, making tight chassis routing a one-person task, and the nickel content prevents galvanic reactions with stainless or aluminum components to keep every union free of hidden corrosion.

The 46-inch length is ideal for ABS module jumpers, master-to-proportioning-valve runs, or custom hot-rod plumbing; trim the tube if you need something shorter, slide the nut back on, and torque to spec. Like every 4LifetimeLines component, this brake line is backed by our Lifetime Warranty, so you can install it once and move on to the next project with confidence.
