42in #3 Line -3 Str/-3 Str

The ALLSTAR PERFORMANCE 42in #3 Line -3 Str/-3 Str is a professional-grade brake hose assembly engineered for custom hydraulic brake system installations, engine bay modifications, and high-performance vehicle builds. This 42-inch hose is designed for enthusiasts and mechanics who demand precise fitment in tight engine compartments or complex brake line routing scenarios where standard off-the-shelf lengths fall short. Whether you're fabricating a custom brake system for a race car, hot rod, or street machine, this hose provides the flexibility and reach needed to connect master cylinders, proportioning valves, and brake calipers without compromise.

Built with a braided stainless steel outer layer and PTFE (polytetrafluoroethylene) internal lining, the 42in #3 Line -3 Str/-3 Str delivers superior durability and chemical resistance essential for aggressive brake fluid formulations and extended high-temperature operation. The #3 AN (Army Navy) designation specifies a -3 hose bore (3/16-inch inside diameter), while the dual -3 AN straight female fittings at both ends enable direct, leak-free connections without adapters. This configuration minimizes pressure drop, reduces potential leak points, and maintains full hydraulic integrity under extreme pedal pressure and thermal cycling—critical factors in performance braking systems where stopping power cannot be compromised.

Mechanics and fabricators rely on this 42-inch hose for custom brake line runs in engine swaps, turbo installations, and complete chassis modifications where standard hose lengths introduce unsafe routing or inadequate slack. The lightweight construction (0.21 lbs) eliminates unnecessary weight while the compact packaged dimensions make storage and handling convenient during long build sessions. Installation requires AN-standard crimp fittings on the system end components; compatibility is universal across any brake system using -3 AN connections, including DOT-approved hydraulic clutch systems and custom proportioning valve setups on vintage and modern vehicles alike.
