10ft Roll -4 Black Red N ylon Braided Flex Hose

The 10ft Roll -4 Black Red Nylon Braided Flex Hose by Vibrant Performance is a professional-grade fuel and fluid line solution designed for custom automotive builds, engine swaps, and high-performance modifications. As a mechanic working on everything from street machines to track-ready vehicles, you know that OEM rubber hose deteriorates, kinks, and fails under heat and pressure—especially in tight engine bays where space constraints demand flexibility without compromise. This braided flex hose eliminates those headaches by combining durability with the routing freedom critical to serious vehicle work.

Constructed with a nylon braided exterior jacket and internal construction rated for -4 AN (1/4-inch) nominal diameter, this hose maintains pressure integrity across fuel, coolant, and vacuum applications while resisting abrasion, oil, and engine bay heat. The braided nylon weave provides both structural support and flexibility—allowing you to route lines around headers, turbochargers, and custom intake manifolds without kinking or crimping flow. At 10 feet per roll, you have material to fabricate multiple lines for a single project or stock your shop with enough hose to handle several builds, and the lightweight 0.7-pound roll ensures easy handling during installation. The black and red color coding allows quick identification during assembly and troubleshooting.

Professional fabricators and DIY enthusiasts rely on Vibrant Performance braided hose for LS engine conversions, carbureted fuel system upgrades, and custom cooling loops where factory hard-line routing won't work. Whether you're plumbing a fuel cell in a vintage restoration, running lines through a tight engine bay tunnel, or upgrading to premium coolant circulation, the -4 diameter handles moderate flow rates while maintaining pressure under load. Pair this with matching -4 AN fittings and clamps (sold separately) for a clean, leak-free installation that looks as good as it performs. This product is an essential component for any serious modification project where reliability and flexibility matter equally.
