Description
BrakeQuip cunifer brake line tubing is a copper-nickel alloy used as an alternative to plated steel brake line. It is not the soft copper tubing that should never go on a brake system, which is the confusion the name causes most often. Cunifer resists corrosion far better than plated steel, does not need the break-in flaring technique stainless does, and bends and double-flares by hand with ordinary tools, which is why underbody replacements and full custom line jobs are so often built from it. Sold as a 25 foot coil. Choose 3/16″ or 1/4″ above, and confirm the OD your fittings, calipers and clips are built for before ordering, since brake line diameter is not universal across the vehicle it is replacing.
If you are deciding between materials, what cunifer is and why people use it covers the alloy itself, and stainless versus copper-nickel covers the tradeoff between the two.
