9in #4 Line -4 Str/-4 Str

The ALLSTAR PERFORMANCE 9-inch #4 Line -4 Str/-4 Str brake hose delivers precision hydraulic fluid transfer in high-performance applications requiring rugged reliability and consistent pressure delivery. This 9-inch stainless steel braided hose with PTFE lining connects dual 4 AN straight female fittings, making it ideal for brake systems, fuel systems, and power steering applications where compact routing and vibration-resistant construction are essential.

The #4 AN specification denotes a 1/4-inch inner diameter rated for -4 hose sizing, which handles fluid flow requirements in systems requiring controlled pressure regulation. Stainless steel braiding provides corrosion resistance and protection against abrasion in engine bays and undercarriage environments, while the PTFE (polytetrafluoroethylene) interior lining ensures chemical compatibility and minimizes friction for consistent hydraulic response. The 4 AN straight female to 4 AN straight female configuration accommodates standard adapters and manifold ports, simplifying integration into existing brake or fuel system architectures.

Engineered for performance vehicles, racing applications, and custom hydraulic installations where factory hose routing is inadequate or incompatible, this assembly eliminates leakage points and reduces system complexity. The 9-inch length accommodates compact engine bays and tight under-dash configurations without requiring excessive bends or couplers. Weighing only 0.14 pounds with compact dimensions of 4 x 0.5 x 6 inches, this hose integrates seamlessly into lightweight and space-constrained builds.

ALLSTAR PERFORMANCE hoses are engineered to SAE specifications for burst pressure, flexibility, and thermal stability, ensuring compatibility with both DOT-approved and racing-spec brake fluids. Whether upgrading brake lines for track duty, constructing custom fuel delivery systems, or retrofitting power steering applications, this pre-assembled unit eliminates the need for field crimping and guarantees repeatable fitment. Each hose is sold individually, allowing builders to source multiple assemblies for complete system overhauls.
