14in #4 Line -4 Str/-4 Str

The ALLSTAR PERFORMANCE 14in #4 Line -4 Str/-4 Str brake hose is engineered for high-performance hydraulic brake systems where precision fluid routing and reliability are non-negotiable. Whether you're building a custom hot rod, upgrading a race car, or fabricating a modern street machine with aftermarket braking components, this hose delivers the controlled pressure transfer your system demands. Purpose-built for professional mechanics and automotive enthusiasts who refuse to compromise on brake system integrity, this 14-inch assembly provides the exact length needed for mid-engine conversions, custom chassis layouts, and tight engine bay configurations where standard factory hoses fall short.

This brake hose features dual 4 AN straight female connections, allowing seamless integration with industry-standard AN fittings on both caliper and master cylinder sides. The PTFE-lined interior provides superior chemical compatibility and resists fluid degradation, critical for maintaining consistent pedal feel and preventing vapor lock under sustained high-temperature braking. Braided stainless steel construction wraps the PTFE core, offering exceptional durability against abrasion, corrosion, and the thermal cycling inherent in performance driving. The compact 0.16 lb weight and manageable 14-inch length make routing through engine compartments straightforward, while the straight-to-straight female configuration eliminates the need for adapter fittings and reduces potential leak points in your brake circuit.

This hose assembly is ideal for builders working with custom brake master cylinders, remote brake proportioning valves, or dual-brake-system setups common in vintage race cars and competition vehicles. The 4 AN size handles moderate to high brake fluid flow rates while maintaining safe pressure drop across the line, making it suitable for both street and track applications. Proper installation requires hand-tightening AN fittings until snug, then backing off one-quarter turn—never overtighten, as PTFE-lined hoses are more forgiving than steel lines. Compatible with all DOT-approved brake fluids and proven in endurance racing environments where system reliability directly impacts safety and performance.
