Hose PTFE Lined Braided Stainless -4AN x 10ft

The Hose PTFE Lined Braided Stainless -4AN x 10ft from VIBRANT PERFORMANCE delivers reliable fluid transfer for high-performance fuel, oil, and coolant systems in modified vehicles and racing applications. Built for engine builders and performance enthusiasts who demand consistent flow without degradation under pressure, this hose assembly eliminates the risk of fuel permeation and heat-related failures common in stock rubber lines. Whether upgrading a fuel system on a turbocharged build, installing a remote oil cooler, or routing coolant through custom engine bays, this 10-foot length provides the flexibility needed for complex plumbing layouts without multiple splice points.

PTFE (polytetrafluoroethylene) inner liners create a non-permeable barrier that resists fuel vapors, ethanol blends, and aggressive coolants while maintaining structural integrity under sustained temperature and pressure cycling. The stainless steel braided outer weave provides superior abrasion resistance and burst strength compared to single-braid construction, critical in engine compartments where hoses contact sharp edges, exhaust components, or engine block corners. The -4AN sizing (equivalent to 1/4-inch nominal ID) handles substantial flow rates—typical for fuel delivery on forced-induction engines or auxiliary cooling circuits—while remaining compact enough for tight installation paths. Vibrant Performance's engineering ensures the hose maintains flexibility at temperature extremes, preventing brittleness in cold starts and hose separation during thermal cycling.

This hose is ideal for carbureted and fuel-injected engine swaps, turbo return lines, intercooler coolant circuits, and remote-mounted fuel cells where OEM rubber hose fails under boost or elevated temperatures. The 10-foot length accommodates custom engine bay layouts, allowing builders to route lines away from heat sources and moving components without crimping or kinking. Installation requires AN flare fittings on both ends (not included), which must match your fuel rail, carb inlet, cooler, or tank bung specifications. Professional mechanics and dedicated enthusiasts favor this assembly for restoration projects, supercharged applications, and competition builds where fuel system reliability directly impacts performance and safety.
