Copper-Coated Brake Line Kit – 3/16″ × 25 ft

Upgrade tired factory lines with this copper-coated brake line kit—a 3/16″ × 25 ft coil of copper-plated, double-annealed steel that bends easily and flares cleanly. The kit ships with SAE unions, so you have everything needed for a fresh hydraulic run right out of the box.

Why copper-coated steel?
• Classic OE feel, standout look – bends like standard steel while showing a warm copper finish.
• High burst strength – exceeds SAE J527 & FMVSS 106 requirements at > 5,000 psi.
• Clean flaring – the plated surface lets double- or bubble-flares seat on the first try.

What’s in the box
• 25 ft coil, 3/16″ OD copper-plated steel tubing
• Four 3/8-24 inverted-flare brass unions

Ideal for classic restorations, daily drivers, hydro-boost swaps, trailer brake retrofits, and track builds that need extra visual pop.

Fast two-step install

1. Route & bend – uncoil, mark path, hand-bend or use a lever bender (≥ 1.5″ radius).

2. Cut, flare, connect – slide tube nut, make a double flare, torque union to 110 in-lb. Bleed the system and drive.

Shop tip: warm the coil slightly on cold days for the smoothest bends.
