30in #4 Line -4 Str/-4 90 Deg Tube Style

The 30in #4 Line -4 Str/-4 90 Deg Tube Style brake hose from ALLSTAR PERFORMANCE is purpose-built for high-performance vehicles requiring reliable fluid transfer in custom brake system layouts. This 30-inch braided stainless steel hose connects two 4 AN fittings—one straight female inlet and one 90-degree female outlet—allowing you to route brake lines around engine bays, frame rails, and suspension components with precision geometry. Whether you're upgrading a street rod, race car, or heavily modified daily driver, this hose accommodates the angular transitions and tight spaces that stock routing cannot handle.

Constructed with PTFE (polytetrafluoroethylene) lining and a braided stainless steel outer layer, the 30in #4 Line -4 Str/-4 90 Deg Tube Style resists abrasion, heat degradation, and pressure surges that commonly fail rubber hose in performance applications. The PTFE core provides chemical resistance to brake fluid while maintaining flexibility for installation in tight routing scenarios, and the braided stainless reinforcement prevents expansion under the sustained pressure of high-performance braking systems. The 4 AN connection size (common in engine bay and suspension plumbing) ensures compatibility with industry-standard fittings and proportioning blocks used in custom brake builds.

Builders and mechanics favor this hose length and configuration for custom brake system installations where factory lines don't fit modified chassis layouts or relocated master cylinders. The straight-to-90-degree fitting arrangement eliminates the need for multiple adapter fittings, reducing leak points and simplifying the assembly process during full system rebuilds or brake balance adjustments. Installation requires standard AN wrench sizes and basic hose assembly experience; ensure all connections are torqued evenly to prevent stress cracking at the fitting collar.
