About this item

  • Nickel Copper Bends and Flares with Ease: Our premium nickel-copper brake lines are engineered for effortless bending and flaring. The material's exceptional flexibility allows for precise, tight bends without the risk of kinking or compromising the integrity of the line. Perfect for custom installations and complex routing in automotive applications.
  • Ideal Application for Fuel and Transmission Line Replacement: Designed for versatility, these brake lines are not just limited to braking systems. They are ideal for replacing old or worn fuel and transmission lines. The nickel-copper composition ensures compatibility with a wide range of automotive fluids, providing reliable performance and extending the lifespan of your vehicle’s fluid transfer systems.
  • Durable and Rust Resistant: Our brake lines are constructed from a high-grade nickel-copper alloy, offering superior resistance to corrosion and rust compared to traditional steel lines. This durability ensures long-lasting performance, even in harsh environmental conditions, such as exposure to road salt, moisture, and varying temperatures.
  • Bends with Ease: Say goodbye to the struggle of bending rigid brake lines. Our nickel-copper lines are designed to bend effortlessly with minimal force, making installation quick and easy. This ease of manipulation reduces the risk of cracking or breaking during the installation process, ensuring a smoother, faster setup.
  • Easy to Flare: Achieving professional-quality flares is simple with our brake lines. The malleable nature of the nickel-copper alloy makes it easier to create precise, leak-free flares, whether you are using a manual flaring tool or a hydraulic one. This reliability in flaring ensures a secure fit and helps prevent fluid leaks, contributing to the overall safety and efficiency of your braking or fluid transfer system.

Ill never buy steel again. It is real nickel copper. Made brake lines with this stuff. Its great to work with and double flares beautiful with a regular old cheap flaring tool. And I'm a novice.

I made a fuel line for a vehicle with it and it worked great, but you need the proper tools for bending or it will kink on you! I will definitely purchase again.

Twice the cost of steel lines, but you'll never have to do them again. It can be a little tedious getting the flare correct. My first bar style tool clamped the line so tight it deformed the line, and punctured the thin wall a few times. I found an older worn down bar style tool that doesn't clamp as hard when tightened. Actually worked perfectly. Just make sure everything is straight and true before starting. And give yourself extra length to make some mistakes.

Great product, a little pricey, but worth every penny. Strong enough, doesn't rust and can bend it to desired shape very easily. I always keep a 25 ft roll of 5/16 and 3/16 in my home garage for trans, fuel, and brake lines.

So i used this line to replace an old rusted fuel line on my truck. The amount of line that i got was more than enough to replace my fuel lines mess up because of course i didn't measure it right and redo it once more. I fully intend on replacing my brake lines with it too. The biggest selling point for me was that it doesn't corrode as fast as steel lines. Easy to bend without kinking it and it's kinda pretty compared to the rest of the old rusty undercarriage. 9 out of 10 would buy again.

I had to replace the entire fuel system on my truck. This was used as a return line and it was AWESOME to work with. Very easy to bend with no tools worth every penny.

This is a lot cheaper than the stuff you can buy at the auto parts store, but it works just as well. Super flexible and easy to work with.
