4LIFETIMELINES Copper-Nickel Brake Line Kit 3/16in x 25ft — Hand-Bendable, Corrosion-Resistant with Inverted-Flare Fittings

4LIFETIMELINES 3/16" x 25 ft copper-nickel brake line kit is a hand-bendable, corrosion-resistant replacement set that includes a 25-foot coil and 16 inverted-flare fittings for full brake-line runs.

This kit supplies a continuous 25-foot length of 3/16" copper-nickel tubing plus the most commonly used inverted-flare fittings so you can replace corroded steel lines without welding or specialty bending tools. The copper-nickel alloy combines flexibility with endurance, meeting SAE and ISO specifications to fit passenger cars, trucks, and SUVs. The tubing is optimized for cold-weather and coastal conditions where road salt and moisture accelerate rusting in conventional steel brake lines.

How easy is it to bend and shape the tubing during installation?

The copper-nickel alloy is engineered for high ductility so technicians and DIYers can hand-bend runs without kinked sections or collapse. Bending by hand reduces the need for expensive tubing benders and speeds up routing along chassis lines.

• Hand-bendable 3/16" tubing—no special bending tools required
• Resists kinking and maintains internal diameter through bends
• Works with standard flaring tools for inverted flare fittings

Will this tubing resist corrosion in salty or humid environments?

Copper-nickel is markedly more resistant to rust, road salt, and moisture than plain steel, which helps extend service life in coastal and winter climates. Use it where traditional steel lines show pitting or where frequent exposure to deicing salts shortens component lifespan.

• Nickel-copper alloy formulated for enhanced corrosion resistance
• Suitable for salt-prone roads and humid coastal conditions
• Less frequent need for replacement compared to uncoated steel

Does the kit include the fittings I need for a complete replacement?

Yes, the kit ships with 16 inverted-flare tube nuts sized for common brake connections so you can complete most full-line replacement runs. The mix covers the typical fittings used on a wide range of vehicles, minimizing trips back to the parts store.

• 16 inverted-flare fittings included for direct-fit connections
• Fitting sizes: 2x 7/16-24, 10x 3/8-24, 2x 1/2-20, 2x 9/16-18 (tube nuts)
• 25 ft coil provides adequate length for most cars, trucks, and SUVs

Is this tubing held to industry standards for safety and performance?

The tubing is manufactured and tested to meet relevant SAE and ISO specifications, ensuring consistent dimensions and material properties for reliable brake-fluid delivery. Compliance helps when matching replacement lines to factory systems and when documenting repairs.

• SAE and ISO certified for material and dimensional compliance
• Compatible with standard inverted-flare brake fittings and flares
• Designed for direct replacement of steel brake tubing runs

Who is this for: Professional mechanics, restoration shops, and competent DIY vehicle owners who need a durable, easy-to-install alternative to steel brake tubing will find this 4LIFETIMELINES kit useful. It's best suited for full-line replacements on cars, light trucks, and SUVs—especially if you work in coastal areas, high-humidity regions, or climates that use road salt in winter. The included fitting assortment and hand-bendable coil reduce the need for specialty tools while meeting SAE and ISO expectations for material quality and fitment.
