24in #4 Line -4 Str/-4 Str 5pk

The ALLSTAR PERFORMANCE 24-inch #4 Line Brake Hose 5-Pack (SKU ALL46400-24-5) delivers professional-grade hydraulic fluid transfer for high-performance braking systems. Each hose measures 24 inches in length and features 4 AN (AN4) straight female fittings on both ends, engineered for seamless integration into dual-line hydraulic brake circuits. The braided stainless steel construction with PTFE inner lining provides corrosion resistance and reliable pressure containment across repeated thermal cycles, critical for motorsport applications where brake fluid temperatures exceed 200°F.

AN4 hose fittings maintain industry-standard 37-degree JIC male connector geometry, ensuring leak-free assembly with compatible proportioning valves, master cylinders, and caliper inlet ports. The PTFE fluoropolymer core resists fluid degradation and maintains flexibility across the full operating range, while braided stainless steel prevents expansion under peak pressure. The 5-pack format supports complete brake line replacement on dual-circuit systems or provides spare hose for track-day backup and field repairs. At 0.95 lbs total, the set integrates into compact engine bays without adding unnecessary weight.

This hose assembly serves drag racers, road race competitors, and hot rod builders who demand consistent pressure transfer without failure. High-performance street cars, classic restorations, and dedicated track vehicles all benefit from the reliability of stainless braided hose in lieu of rubber lines that degrade under sustained heat. Straight-to-straight female AN4 fittings simplify installation where direct line routing is required, eliminating the need for additional adapter fittings and reducing connection points.

ALLSTAR PERFORMANCE's brake hose lineup is recognized throughout the motorsport aftermarket for consistent quality and fitment. The 24-inch length accommodates common dual-disc and dual-drum brake system layouts, though custom lengths are available for specialized circuits. Stainless braided hose has become the industry standard in performance applications where OEM rubber cannot withstand brake fluid temperatures or repeated pressure cycling.
