This corrosion-resistant steel tubing is just like the original on most cars. All you need is a tubing bender and flaring tool and you're ready to create a replacement line or even a custom one. Each kit contains 25 ft. of steel tubing (.028" thick wall) and 16 assorted OEM style fittings (master cylinder fittings, short wheel cylinder). All fittings are for SAE double-flaring applications.
