Push-On Rubber Flex Hose -4AN 10ft Roll

The Push-On Rubber Flex Hose -4AN 10ft Roll by VIBRANT PERFORMANCE is engineered for serious performance enthusiasts and professional mechanics who demand reliable fluid transfer in high-heat engine bays and tight underhood spaces. This hose is purpose-built for custom fuel, coolant, and oil line applications where vibration isolation and routing flexibility are critical to system longevity and engine reliability. Whether you're building a modified engine bay, upgrading fuel delivery on a forced-induction platform, or restoring a classic with contemporary plumbing, this -4AN rubber hose delivers the durability and ease of installation that separates quality builds from quick fixes.

Constructed with reinforced rubber and a flexible design, the -4AN sizing accommodates standard -4 AN fittings commonly found in fuel injection systems, turbocharger feed lines, and custom cooling circuits. The push-on connection design eliminates the need for hose clamps or crimping tools—fittings slide on securely with a simple, repeatable interface that reduces assembly time without compromising seal integrity. The 10-foot length provides generous material for routing around engine components, firewall penetrations, and suspension geometry, while the rubber composition resists degradation from fuel, oil, and coolant exposure while dampening vibration transmission that can weaken connections over time. This roll format allows you to cut custom lengths precisely where you need them, minimizing waste and maximizing layout efficiency in confined engine compartments.

This hose excels in street performance, racing, and restoration projects where OEM rigid steel or braided lines don't suit the modified layout. It pairs seamlessly with Vibrant Performance fittings and adapters, making it ideal for fuel system upgrades on naturally aspirated and turbocharged applications, secondary coolant loops, and custom circulation systems. Installation requires only compatible -4AN fittings and a steady hand for routing; the lightweight construction (1 lb per roll) makes it manageable for single-technician installation in tight quarters. Check your existing hose barbs and fittings for -4AN sizing before ordering to ensure proper fitment with your fuel rail, carb adapter, or coolant manifold.
