1/4" x 25' Copper-Nickel Brake Line Kit – Includes Steel Fittings

The 4LifetimeLines 1/4″ x 25′ Copper-Nickel Kit with Steel Fittings combines premium copper-nickel brake line tubing with precision-machined steel fittings to deliver a complete, shop-ready solution for brake line fabrication and replacement. Built from high-quality copper-nickel (CuNi 90/10) alloy, the tubing offers superior corrosion resistance and bendability compared to traditional steel lines—making it ideal for vehicles operating in corrosive environments like coastal regions or salt-belt areas.

This kit includes 25′ of flexible copper-nickel tubing that bends smoothly without kinking, plus a complete set of steel SAE inverted-flare fittings for secure, leak-resistant connections. The tubing works easily with standard flaring tools to support both single and double flares, giving technicians confidence in every install. Whether you’re performing routine maintenance, custom routing, or full brake system replacement, this copper-nickel kit helps streamline workflow and improve long-term durability.

Backed by the 4LifetimeLines lifetime warranty, this kit delivers professional-grade performance and corrosion protection technicians can depend on job after job.
