Coated Braided Line 30in #4Hose -4Str/-4 90 Steel

The Coated Braided Line 30in #4Hose -4Str/-4 90 Steel is a precision-engineered brake hose assembly purpose-built for high-performance automotive and motorsport hydraulic systems where reliability under pressure is non-negotiable. Designed for users who demand absolute consistency in brake modulation—from professional racing teams to law enforcement and military vehicle maintenance specialists—this hose eliminates the guesswork in hydraulic line replacement. The 30-inch length and 4 AN (female to 90-degree female) configuration make it an ideal fit for custom engine bay layouts where space optimization and angle-specific connections are critical to system integrity.

Constructed with a braided stainless-steel reinforcement core and lined with PTFE (polytetrafluoroethylene), this hose delivers superior burst resistance, thermal stability, and fluid compatibility across a wide range of brake fluid types, including DOT 3, 4, and synthetic formulations. The black vinyl outer coating provides UV protection and abrasion resistance, shielding the reinforcement from direct contact with engine heat, fuel, or corrosive underbody environments. The 4 AN straight female to 4 AN 90-degree female configuration enables seamless integration into systems requiring both direct and angled manifold connections, reducing fitment stress on adjacent components and extending overall system longevity. At 0.29 lbs, the hose's compact weight profile minimizes dead mass while maintaining full pressure-handling capability up to demanding motorsport specifications.

This assembly is essential for custom brake system builds, high-performance vehicle restoration, and military/tactical vehicle maintenance where OEM hoses may not accommodate modified layouts. Technicians and fabricators benefit from the pre-assembled configuration, which eliminates on-site swaging and reduces labor time during installation. Compatibility spans any hydraulic brake system using 4 AN fittings—including domestic muscle cars, import sport sedans, race-spec platforms, and armored or tactical vehicles requiring redundant or upgraded braking architecture. Installation requires only standard AN wrench sizes; tight coil spacing ensures minimal flex under load, maintaining critical brake line pressure consistency during high-deceleration events.
