The 30in #4 Line -4 Str/ 1/8in NPT straight brake hose from Allstar Performance is engineered for high-pressure hydraulic brake systems in custom vehicles, racing applications, and performance builds where stock routing won't fit. This 30-inch braided stainless steel assembly connects your master cylinder or proportioning valve to brake calipers with precision fittings and leak-free integrity—critical when stopping power matters. Whether you're assembling a street rod, circuit car, or custom truck, this hose delivers the reliability needed for consistent pedal feel and fade-free performance.
The hose features a 4 AN (1/4-inch) braided stainless steel outer jacket protecting a PTFE (Teflon) inner core, which resists heat, abrasion, and chemical degradation better than rubber alternatives. The configuration includes a 4 AN straight female end paired with a 1/8-inch NPT straight male end, allowing flexible adapter options for both metric and SAE brake systems. At just 0.23 lbs and compact at 4.4 x 1.3 x 6.05 inches, the 30-inch length fits tight engine bays while the braided construction withstands high-pressure transients and vibration without cracking or weeping, maintaining structural integrity across temperature extremes from coolant passages to hot underbody environments.
Technicians and builders choose this brake hose for custom hydraulic layouts where OEM routing is incompatible with modified suspension, engine swaps, or non-standard brake component placement. The mix of 4 AN and 1/8 NPT ends makes it ideal for bridging proportioning valves, master cylinders, or differential brake switches to remote caliper packs or modulating systems. Installation requires basic AN fitting tools and careful torque to avoid over-tightening the NPT male end; always use thread sealant tape or Teflon paste on the NPT connection to prevent weeping under pressure. This hose is DOT-approved for street use and trusted by fabricators building everything from vintage hot rods to modern performance platforms.
