#6 Auto-Flex Hose 6ft

The #6 Auto-Flex Hose 6ft from EARLS is a professional-grade braided stainless steel and rubber hose assembly designed for high-performance automotive fuel, oil, and coolant systems. Built for racers, performance enthusiasts, and technicians who demand reliability under demanding conditions, this hose combines flexible routing capability with the durability needed for motorsports and modified engine applications. The 6-foot length provides sufficient reach for custom engine bay layouts while maintaining compact storage and installation footprint.

Constructed with braided stainless steel outer reinforcement and synthetic rubber inner core, the #6 Auto-Flex Hose resists abrasion, vibration fatigue, and thermal cycling—critical factors in turbocharged or supercharged engine environments. The stainless braid provides superior kink resistance compared to non-braided alternatives, allowing tighter bends without restricting flow or compromising structural integrity. The Auto-Flex design permits dynamic flexing during engine operation and thermal expansion cycles, reducing stress concentrations at connection points and extending overall system lifespan. Rated for 6 AN (AN6) specification, this hose is engineered to handle fuel pressures and flow rates common in carbureted, EFI, and fuel-injected performance engines.

This hose assembly is ideal for custom fuel systems, cooling loops, and oil circulation upgrades in street rods, drag cars, and track vehicles. Installation requires compatible 6 AN fittings at each end (sold separately); ensure all connections are properly torqued to prevent leaks under pressure. The natural (undyed) stainless and rubber construction makes it compatible with gasoline, methanol, and most synthetic fluids used in motorsports applications. Professional installers and serious DIY builders choose EARLS Auto-Flex hoses for their proven performance record in high-vibration, high-temperature environments where standard hose would fail.
