4LIFETIMELINES Copper Nickel Brake Line Kit [2-Pack] – 3/16" & 1/4" x 25 ft Tubing Coils with Fittings | Rust-Resistant CuNi Replacement Brake Lines | Easy Bend & Flare

• 2 COMPLETE BRAKE LINE KITS WITH FITTINGS – Each kit includes one 3/16" x 25 ft and one 1/4" x 25 ft copper-nickel tubing coil plus a full assortment of tube nuts and union fittings in both sizes. Everything you need for a front-to-rear brake line replacement, transmission cooler line, or fuel line repair — no extra trips to the parts store.
• RUST-PROOF COPPER-NICKEL (CuNi) CONSTRUCTION – Unlike plain steel brake lines that corrode from the inside out, our 90/10 copper-nickel alloy resists rust and salt corrosion on both the interior and exterior surfaces. Ideal for vehicles in northern climates, coastal areas, and anywhere road salt and moisture attack brake line integrity.
• EASY TO BEND, CUT & FLARE BY HAND – Copper-nickel tubing is significantly softer and more workable than steel, allowing you to route and shape brake lines without a power bender. Compatible with standard inverted flare (SAE) fittings and any double-flare or bubble-flare tool. Perfect for DIY mechanics and professional shops alike.
• BUILT FOR EXTREME TEMPERATURES & HIGH PRESSURE – Engineered to handle the thermal demands of hydraulic brake systems, from freezing winter starts to high-heat braking conditions. These lines maintain structural integrity and consistent brake pressure across a wide temperature range, giving you reliable stopping power year-round.
• UNIVERSAL FIT FOR CARS, TRUCKS, SUVs & TRAILERS – Standard 3/16" and 1/4" OD sizes work on virtually any domestic or import vehicle. Meets or exceeds ASTM B111 and SAE J527 standards for automotive brake line tubing. Use for front brake lines, rear brake lines, transmission lines, fuel lines, and hydraulic applications.
