15in #4 Line -4 Str/-4 Str

The ALLSTAR PERFORMANCE 15in #4 Line -4 Str/-4 Str brake hose is designed for automotive builders and mechanics who require precise hydraulic brake lines for custom vehicle projects. This straight-to-straight configuration ensures reliable brake fluid transfer in high-performance street builds, race cars, and restoration work where OEM brake line routing may not fit custom setups.

At 15 inches in length, this hose effectively connects master cylinders, proportioning valves, and wheel cylinders in non-standard installations. Built with #4 SAE hose sizing, it features -4 AN (JIC) straight fittings at both ends, which correspond to a bore diameter of 0.25 inches with industry-standard AN male threads. The dual straight-to-straight termination minimizes bends and dead zones in the brake system, ensuring optimal pedal response and stopping power.

This hose is essential for mechanics and builders working on custom hydraulic brake setups, hot rod frame-ups, or engine swaps, providing compatibility with most custom brake system components available from performance suppliers. Weighing just 0.17 pounds, it balances durability with a minimal weight penalty, making it ideal for weight-conscious builds.
