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 foot of steel tubing (.028in. thick wall) and 16 assorted fittings (6 master cylinder fittings, 5 short wheel cylinder and 5 long wheel cylinder fittings). All fittings are for SAE double-flaring applications.
