• COMPLETE 1/4" BRAKE LINE KIT — READY TO INSTALL: Includes one 1/4" x 25' coil of 316L stainless steel brake line tubing plus 16 inverted flare fittings — (10) 1/4" 7/16-24 inverted long, (2) 1/4" 7/16-24 inverted, (2) 1/4" 9/16-18 inverted, and (2) 1/4" 1/2-20 inverted. Everything you need for a complete brake line replacement in one kit — no extra parts to source.
• 316L MARINE-GRADE STAINLESS STEEL: Not generic stainless — this is 316L marine-grade, the same alloy used in saltwater and chemical processing environments. It resists corrosion and rust far longer than galvanized steel or copper-coated lines, making it the go-to choice for vehicles in salt-belt states, coastal regions, or anywhere road salt and moisture eat through conventional brake lines.
• EASY TO WORK WITH — BENDS, CUTS & FLARES CLEANLY: The 0.028" wall thickness gives you the strength you need without fighting the tube during installation. Bends smoothly with a standard tubing bender, cuts clean with a tube cutter, and accepts both single and inverted (double) flares. No specialty equipment required — built for DIY home mechanics and professional shops alike.
• UNIVERSAL 1/4" FITMENT — BROAD APPLICATION RANGE: The 1/4" OD fits 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 vehicle maintenance. The 25-foot coil provides enough length to run multiple lines from a single kit.
• BUILT TO OUTLAST YOUR VEHICLE: 316L stainless steel doesn't weaken, pit, or flake over time the way standard steel or coated lines do. It holds up against road salt, moisture, heat cycling, and chemical exposure season after season without degrading. Install it once and stop worrying about rust-related brake line failures — this is the last brake line your vehicle will need.
• MEETS SAE & ISO SPECIFICATIONS: This tubing meets all SAE and ISO standards for automotive brake line applications. The inverted flare fittings provide a leak-free, high-pressure seal at every connection. Compatible with DOT 3, DOT 4, and DOT 5.1 brake fluids. Engineered for safety-critical braking systems where reliability matters most.
