1/4" × 135" Copper-Nickel Brake Line – Pre-Flared, Ready to Install

Put an end to seized steel tubing with a copper nickel brake line built to last. This RightQuick 1/4-inch, 135-inch tube arrives double-flared and threaded with common 7/16-24 and 1/2-20 inverted-flare fittings already in place, turning what used to demand specialty tools into a straightforward cut-to-fit swap.

Drawn from a 90-10 CuNi alloy, the line pairs copper’s easy workability with nickel’s exceptional resistance to salt, moisture, and road chemicals. It outlives 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 standards, delivering OEM-grade safety mile after mile.

At 135 inches, this length spans master-to-ABS modules, frame-to-axle runs, or custom street-rod plumbing with room to trim for an exact fit. Because the fittings are pre-installed, you simply route the tube, make any final cut if needed, slide the nut back, and torque to spec—no expensive flaring kit required.

Copper nickel bends up to sixty-five percent easier than steel, so threading tight chassis curves becomes a one-person task. The nickel content blocks galvanic reactions with stainless or aluminum components, safeguarding every union from hidden corrosion and ensuring trouble-free service down the road.
