BSTIQUEUS 25ft 1/4" Copper-Nickel Brake Line Kit — .028" Wall, 16 Fittings, Corrosion-Resistant

BSTIQUEUS 25ft 1/4" copper-nickel brake line kit is a full-length, corrosion-resistant tubing set with a .028" wall and 16 standard fittings for reliable brake-line replacement and custom runs.

This kit supplies a continuous 25-foot length of 1/4" copper-nickel alloy tubing engineered to meet SAE and ISO standards, plus a range of inverted tube nuts for common vehicle applications. The tubing’s composition (approximately 88.1% Cu, 9.7% Ni, 1.4% Fe, 0.8% Mn) delivers bendability for double-flaring, solid resistance to rust and road chemicals, and long-term dimensional stability. Whether you’re repairing corroded lines or routing new brake runs on a restoration or race car, the kit contains the core materials needed for a professional installation.

How does this copper-nickel tubing compare to standard steel brake lines?

Copper-nickel (Cu-Ni) tubing resists rust and corrosion far better than ordinary steel, which reduces leak risk and maintenance over time. Its non-magnetic, alloyed composition keeps wall thickness stable while remaining soft enough for clean double-flare formation and controlled bending.

• Superior corrosion resistance versus mild steel—ideal for salt and wet climates
• Consistent wall thickness (.028") for reliable flare formation
• Flexible enough for precise routing without kinking

What fittings come with the kit and will they fit my vehicle?

The kit includes 16 inverted tube nuts in commonly used thread sizes, covering most domestic and many import brake-fitting standards. These fittings allow you to mate the tubing to existing components like master cylinders, proportioning valves, ABS modules, and calipers when inverted-type fittings are used.

• 2 × 1/4" (7/16-24) inverted tube nuts
• 10 × long 1/4" (7/16-24) inverted tube nuts for deeper connections
• 2 × 1/4" (1/2-20) and 2 × 1/4" (9/16-18) inverted tube nuts for varied fittings

How does the tubing perform during installation and flaring?

The alloy’s ductility makes it easy to bend and double-flare without cracking, producing reliable, leak-resistant joints when flared correctly. Installers find it holds shape well after bending, reducing spring-back and helping maintain precise line routing under the chassis.

• Supports smooth double-flaring for inverted fittings
• Flexible for hand bending or with a tube bender—resists kinking
• Stable material properties simplify measured runs and repeatable results

What about longevity and maintenance—how long can I expect these lines to last?

Copper-nickel alloy is highly resistant to corrosion from moisture, salt, and road grime, extending service life compared with untreated steel lines. While exact lifespan depends on environment and use, the material’s corrosion resistance and non-magnetic nature reduce the need for premature replacement in harsh conditions.

• Excellent resistance to rust and road salt
• Reduced risk of pitting and through-wall corrosion
• Backed by a lifetime warranty for replacement or exchange

Who is this for: This kit is targeted at automotive technicians, restoration enthusiasts, and DIY mechanics who need a long, reliable run of copper-nickel brake tubing plus common inverted fittings. It suits projects ranging from full brake-line replacements and custom routing on classic cars to performance or off-road builds in corrosive climates where durability and ease of installation matter most.
