4LIFETIMELINES – 1/4" x 25' Copper-Nickel Brake Line Kit with 16 SAE Fittings | True CuNi Alloy, Non-Magnetic | Inverted Flare, 0.028" Wall | Rust-Proof Replacement Tubing for Cars & Trucks

All-in-one copper-nickel brake line kit for easier replacements

Upgrade or restore your braking system with the 4LIFETIMELINES 1/4" x 25' brake line kit. This ready-to-install package combines a full 25-foot coil with a complete fittings set, ensuring you have the parts you need for a full line replacement. The coil length supports multiple lines from a single kit, making it a practical choice for DIY projects, restorations, or fleet maintenance.

Why CuNi matters: rust-proof and non-magnetic

Constructed from genuine copper-nickel alloy, the tubing stays non-magnetic and resists rust and corrosion far better than typical steel lines. In salt belts or coastal environments, this material helps maintain consistent performance by reducing the risk of corrosion-related failures over time. The material also lends itself to smooth bends and clean flares, contributing to a neat, professional install.

Ease of installation for DIYers and pros

The 0.028" wall thickness provides enough strength without compromising workability. Copper-nickel is softer and more malleable than stainless steel, so you can bend by hand and route around components with minimal risk of kinking. It accepts both single and inverted flares using a basic flare tool.

• Includes one 25' coil and 16 inverted flare fittings—everything needed for a complete replacement, no extra parts required.
• Meets SAE J527 and ISO standards for automotive brake lines and is compatible with DOT 3, DOT 4, and DOT 5.1 fluids.
• Universal 1/4" OD fitment covers a broad range of domestic and import vehicles, including classic restorations.
• Built to resist road salt, heat cycling, and chemical exposure, offering long-term reliability.

What you get and how it helps

This kit is designed to be a comprehensive solution for brake line replacements or rust repairs. With the required fittings included, you can replace or extend lines with fewer trips to suppliers, helping you save time and reduce project downtime.

Whether you’re a weekend wrench or an automotive pro, you’ll appreciate the predictable flare results and steady high-pressure seals at each connection. The copper-nickel material reduces the risk of brittle failures over time, giving you confidence in your build or restoration project.
