• COMPLETE 1/4" BRAKE LINE KIT — READY TO INSTALL: Includes one 1/4" x 25' coil of true copper-nickel alloy brake line tubing plus 16 inverted flare fittings — (2) 1/4" 7/16-24 inverted tube nuts, (10) 1/4" 7/16-24 inverted tube nuts (long), (2) 1/4" 9/16-18 inverted tube nuts, and (2) 1/4" 1/2-20 inverted tube nuts. Everything you need for a complete brake line replacement — no extra parts to source.
• TRUE COPPER-NICKEL ALLOY — NON-MAGNETIC: Made from genuine CuNi alloy, not copper-coated steel. Copper-nickel is inherently non-ferrous, meaning it cannot rust — ever. It won't pit, flake, or corrode the way standard steel or even coated steel lines do. If you've dealt with rusted-out brake lines, this is the permanent fix. Ideal for daily drivers, classic restorations, and vehicles in salt-belt or coastal climates.
• EASIEST BRAKE LINE TO WORK WITH — BENDS & FLARES EFFORTLESSLY: Copper-nickel is softer and more malleable than stainless steel, so it bends by hand, routes around chassis components without kinking, and flares cleanly with a basic flare tool. Accepts both single and double (inverted) flares. The 0.028" wall thickness provides strength without sacrificing workability. No specialty tools required — perfect for DIYers and pros.
• MEETS & EXCEEDS SAE AND ISO SPECIFICATIONS: This tubing meets all SAE J527 and ISO standards for automotive brake line applications. The 0.028" wall thickness and inverted flare design ensure a leak-free, high-pressure seal at every connection point. Compatible with DOT 3, DOT 4, and DOT 5.1 brake fluids. Engineered for safety-critical braking systems where failure is not an option.
• UNIVERSAL 1/4" FITMENT — DOMESTIC & IMPORT: The 1/4" OD is a standard brake line size found across a wide range of domestic and import vehicles. Use this kit for full brake line replacements, partial rust repairs, classic car restorations, custom builds, or fleet maintenance. The 25-foot coil gives you enough length to run multiple lines from a single kit.
• BUILT TO OUTLAST YOUR VEHICLE: Copper-nickel alloy doesn't degrade over time the way steel lines do. It resists road salt, moisture, heat cycling, and chemical exposure year after year without weakening. The tubing also provides excellent puncture resistance and won't become brittle with age. Install it once and stop worrying about brake line failures — this kit is built to go the distance.
