Flare Caps; Size: -10 AN

The Flare Caps -10 AN fitting by Vibrant Performance is an essential component for any serious fuel system, coolant loop, or custom fluid line installation. These adapters serve as termination points for AN hose systems, providing a secure, professional-grade connection that prevents leaks in high-pressure applications. Whether you're building a street rod, race car, or modifying an engine bay with aftermarket fuel injection or turbo cooling lines, -10 AN fittings are the industry standard for reliability and performance.

Vibrant Performance's Flare Caps feature precision-engineered 37-degree JIC flare geometry that mates perfectly with standard AN hose ends, ensuring zero leakage under pressure. The -10 designation refers to the hose size—specifically 5/8-inch OD tubing—making these caps suitable for moderate to high-flow applications in fuel rails, coolant systems, and vacuum-operated components. The compact design (3 x 1.2 x 3.6 inches) allows for flexible routing in tight engine compartments, while the minimal weight (0.06 lbs) ensures no measurable impact on vehicle dynamics or fuel system balance.

Mechanics and fabricators choose Vibrant Performance Flare Caps when capping off unused AN ports or terminating fuel lines at filter housings, surge tanks, and distribution blocks. Installation is straightforward—hand-tighten the cap onto the female AN port, then snug with a wrench to ensure a leak-free seal without over-torquing the fitting. Compatibility spans all vehicles using -10 AN hose systems, from street machines to competition platforms, making this a must-have inventory item for any shop performing fuel system upgrades, turbo installations, or custom plumbing work.
