20ft Roll -4 Black Nylon Braided Flex Hose

The VIBRANT PERFORMANCE 20ft Roll -4 Black Nylon Braided Flex Hose (Part #11974) is a high-capacity hose assembly designed for fluid transfer in performance and racing applications. At 20 feet in length with a -4 AN fitting size, this hose delivers the diameter and flow capacity required for fuel, coolant, and hydraulic line routing in custom engine builds, fuel system upgrades, and competition vehicle setups. The nylon braided construction combined with rubber inner core provides both flexibility for tight engine bay layouts and durability under the thermal and pressure cycling typical of high-performance use.

The -4 AN size corresponds to 1/4-inch nominal bore, a standard in motorsports fuel and cooling systems where modest flow rates are acceptable and space constraints demand compact diameter routing. Nylon braiding provides abrasion resistance and visibility of the inner hose condition, while the black outer color resists UV degradation and blends seamlessly with modern engine bay aesthetics. The 20-foot length accommodates full-vehicle routing without multiple splice points, reducing pressure drop and simplifying installation. This hose meets the straightforward durability demands of street performance, autocross, drag racing, and off-road competition platforms.

Buyers sourcing braided hose for custom fuel systems, radiator overflow lines, power steering circuits, or vacuum routing will find this 20-foot roll a practical alternative to shorter pre-made assemblies or multiple hose segments requiring fittings and clamps. VIBRANT PERFORMANCE hose is recognized in the performance automotive community for consistent construction and reliable pressure containment across repeated thermal cycles. The extended length minimizes the need for custom crimping or splicing, reducing both labor and potential leak points in completed installations.
