Nstarsmotor 25ft Copper-Nickel Brake Line Kit .028" Wall with SAE 16 Fittings — Corrosion-Resistant, Easy-to-Form

Nstarsmotor's 25ft copper-nickel brake line kit is a complete corrosion-resistant replacement set designed for lasting performance and easy installation.

This brake line kit supplies twenty-five feet of .028" wall copper-nickel tubing plus a full complement of SAE 16 inverted fittings so you can replace worn or rusted brake lines with material that resists salt and corrosion. Built to SAE/ISO standards and alloyed for durability, the tubing bends cleanly and accepts double flares for a professional finish. The kit is intended for do-it-yourself mechanics and shops that need reliable brake lines without the ongoing rust problems associated with mild steel tubing.

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

Copper-nickel (CuNi) tubing combines flexibility and corrosion resistance. Unlike unprotected steel, CuNi resists pitting and salt-induced rust, extending service life in wet or salted-road environments. It also stays non-magnetic and is easier to shape and flare for accurate fittings.

• Highly resistant to road salt and corrosion for longer service life.
• Cleaner bending behavior reduces kinking during installation.
• Compatible with standard double-flare tools and fittings.

What fittings and components are included in this kit?

The Nstarsmotor kit includes a selection of SAE 16 inverted tube nuts to match common brake line connections, providing flexibility for various vehicle layouts. Fittings are sized and counted to handle multiple runs or repair jobs without buying additional hardware.

• 2 x 1/4” (7/16-24) inverted tube nuts.
• 10 x 1/4” (7/16-24) long inverted tube nuts for deeper thread engagement.
• 2 x 1/4” (1/2-20) and 2 x 1/4” (9/16-18) inverted tube nuts.

Is this tubing easy to form and flare for a DIY brake-line project?

Yes—copper-nickel alloy is favored for shop and DIY work because it bends smoothly and accepts double flares cleanly. The tubing's composition minimizes cracking during bending, and it works well with conventional tube-bending and flaring tools used in brake-line fabrication.

• Material alloys: ~88.1% copper, 9.7% nickel for ductility and strength.
• Accepts double flares reliably with standard flaring tools.
• Bends easily for tight routing without kinking when using proper technique.

What warranty and standards backing does this product offer?

Nstarsmotor manufactures this line to meet SAE and ISO standards; the tubing's composition and production processes conform to widely accepted specifications. The kit is backed by a lifetime warranty and responsive customer support for returns or technical help.

• Meets applicable SAE and ISO requirements for brake tubing.
• Lifetime warranty with returns and exchanges handled by the manufacturer.
• Dedicated customer support for fitment and installation questions.

Who is this for? This 25ft Nstarsmotor copper-nickel brake line kit is aimed at independent mechanics, restoration shops, and experienced DIYers who need a durable, rust-resistant replacement for corroded steel brake lines. It's especially well suited for vehicles driven in snowy, coastal, or salted-road regions where corrosion is a recurring problem. If you need tubing that forms and flares reliably while delivering long-term protection from rust, this kit provides the length, fittings, and alloy composition most projects require.
