4LIFETIMELINES Copper-Nickel Brake Line Kit 3/16" x 7.6 m — Hand-Bendable Tubing, 16 Inverted-Flare Fittings

4LIFETIMELINES 3/16" x 25 ft copper-nickel brake line kit is a ready-to-install replacement coil that combines hand-bendable tubing with 16 inverted-flare fittings for full brake-line repairs.

If you need to replace corroded or damaged brake lines, this kit supplies 25 feet of 3/16" copper-nickel tubing plus a selection of commonly used inverted flare tube nuts so you can run new lines without hunting down extra fittings. The copper-nickel alloy is engineered to resist rust, road salt and moisture while remaining flexible enough to bend by hand, making routing and flaring easier than with stiff steel pipe. SAE and ISO testing means the tubing meets recognized industry benchmarks for material and dimensional quality.

How does copper-nickel tubing perform compared with traditional steel brake lines?

Copper-nickel alloys offer superior corrosion resistance compared with standard steel tubing, which helps extend service life in moist or salted environments. The alloy keeps a smooth inner bore for consistent brake fluid flow and avoids the extensive rust pitting that plagues mild steel lines.

• Better resistance to road salt, moisture and coastal air
• Reduced likelihood of rust-induced leaks or weak points
• Smooth inner surface supports reliable hydraulic flow

Can I bend and flare this tubing without special tools?

Yes — the copper-nickel alloy is intentionally flexible so many bends can be formed by hand, simplifying fitment in tight engine bays or undercarriage layouts. For final flares and professional-grade connections, using a flaring tool is recommended, but hand shaping will often get tubing into place before final trim and flaring.

• Hand-bendable for quick routing and mock-up
• Compatible with standard flaring tools for inverted flares
• Coil format lets you cut lengths to suit any vehicle run

What fittings are included and will they fit my vehicle?

The kit includes 16 inverted flare tube nuts sized to cover the most common vehicle connections, so you can usually complete a full-line replacement without buying additional hardware. Sizes are supplied to match typical SAE inverted-flare threads used on cars, trucks and SUVs.

• 2 x 3/16" (7/16-24) tube nuts
• 10 x 3/16" (3/8-24) tube nuts
• 2 x 3/16" (1/2-20) and 2 x 3/16" (9/16-18) tube nuts

Is this tubing certified and suitable for full brake-line replacement?

The 4LIFETIMELINES tubing is manufactured to meet SAE and ISO specifications, which aligns it with accepted automotive material and dimensional standards. While certifications confirm the tubing’s suitability, installers should follow vehicle manufacturer recommendations and proper brake-bleeding procedures when performing replacements.

• SAE- and ISO-tested for material and tolerances
• Full 25-foot coil covers most complete brake runs
• Designed as a direct replacement for steel brake tubing

Who is this for? This kit is targeted at DIY mechanics, restoration shops and professional technicians who need a corrosion-resistant, flexible brake line solution for cars, trucks and SUVs. It’s especially useful in coastal or winter-salt regions, for vintage vehicle restorations where replacing entire runs is common, and for anyone who prefers tubing that’s easier to shape and flare than rigid steel. Note: always follow local safety rules and hydraulic brake service procedures; if unsure, seek professional installation.
