Product Description

The Vibrant Performance 18974 is a -4 AN PTFE-lined black nylon braided flex hose offered in a 20-foot roll, designed for builders who need a reliable, high-performance fluid line solution. The PTFE inner liner provides a chemically inert barrier that prevents fuel vapor permeation and holds up against aggressive fluids including race fuels, oils, brake fluid, and coolant. The black nylon outer braid adds abrasion and corrosion resistance while keeping a clean look that won't scuff painted surfaces during installation.

With an operating range from -94°F to 480°F and a 1000 psi operating pressure rating, this hose is built for demanding builds from street performance to full race applications. The 20-foot roll gives fabricators enough material to complete most plumbing runs with room to spare. Compatible with Vibrant's full lineup of -4 AN fittings, it integrates seamlessly into any custom fluid delivery system.
