5ft Roll -4 Black Nylon Braided Flex Hose

The 5ft Roll -4 Black Nylon Braided Flex Hose by VIBRANT PERFORMANCE is an essential component for anyone building or modifying a high-performance fuel, oil, or coolant system. This hose addresses the real-world challenge of routing fluid lines through tight engine bays and around custom headers or turbo installations where rigid piping simply won't fit.

Constructed with a nylon braided exterior and engineered for -4 AN (5/16-inch inner diameter) applications, this hose combines synthetic rubber core material with tight braided reinforcement to handle fuel pressures, oil flow, and coolant circulation without kinking or collapsing under high-pressure pulses. The black nylon braid resists abrasion, UV exposure, and fluid degradation—critical when routing hoses near exhaust manifolds or along engine block surfaces where heat cycling is unavoidable.

VIBRANT PERFORMANCE's manufacturing ensures consistent wall thickness and proper hose integrity, eliminating leaks and failures that compromise engine performance and reliability during aggressive driving or racing conditions. Mechanics and performance builders rely on this 5-foot roll for fuel system conversions, turbocharger plumbing, oil cooler installations, and custom cooling setups on street cars and track vehicles.
