Fuel Hose AN4 AN6 AN8 AN10 Nylon Oil Cooler Line AN Series

Upgrade your performance plumbing with the AN4 AN6 AN8 AN10 Fuel Hose With Nylon-Stainless Steel Inside, Oil Cooler Line. This versatile, high-grade hose is designed to handle oil, fuel, water, and air lines in demanding engine bays. The inner liner is a durable CPE synthetic material, while the outer layer is reinforced with nylon and stainless steel wires, delivering excellent resistance to heat, abrasion, and pressure spikes. With an inner diameter of 5.59 mm and an outer diameter of 11.18 mm, this hose provides reliable flow while remaining flexible enough for tight routing around an oil cooler or fuel system.

Built for performance, this hose tolerates extreme temperatures from -40°F to 350°F (-40°C to 177°C) and supports a working pressure up to 500 PSI, with a burst strength of 30 MPa (4400 PSI). It’s a universal option for oil cooler lines, fuel lines, water lines, and other fluid or air lines in racing or street setups. Note: Not compatible with ethanol-containing gasoline, so use fuels that are ethanol-free when installing this hose. Available in AN4, AN6, AN8, AN10, and AN12 sizes, the hose remains a black, low-profile choice that blends into any engine bay while delivering reliable performance. Lengths are sold in fixed increments (1 m, 3 m, 6 m) per platform requirements. For example, if you order two units in 1 m length, you’ll receive two 1 m pieces rather than a single 2 m piece.

Benefits & Tips

Versatile compatibility: ideal for oil cooler feed/return lines, fuel supply/return lines, water lines, or air lines in performance builds.
Durable construction: nylon outer with stainless steel reinforcement plus a CPE inner liner for chemical resistance and long service life.
Practical installation tips: route away from sharp edges, use appropriate clamps sized to the 5.59 mm inner diameter, and avoid ethanol-containing fuels with this hose to ensure longevity.
