-10AN Fast Flow Fitting

The -10AN Fast Flow Fitting is an essential component for any serious automotive fluid system upgrade, whether you're building a high-performance cooling circuit, fuel delivery system, or custom hydraulic line setup. Designed by JAZ, a trusted name in motorsports engineering, this fitting addresses the core challenge facing engine builders and mechanics: maximizing flow rate while maintaining system integrity under demanding conditions.

If you're modifying your vehicle's cooling, fuel, or brake systems, this -10AN fitting enables the larger diameter tubing necessary to reduce pressure drop and heat buildup in critical fluid pathways. The -10AN designation corresponds to a 5/8-inch inner diameter hose size, which allows for improved flow characteristics. This "fast flow" design minimizes turbulence, reduces temperature rise, and decreases system wear on mechanical seals and bearing surfaces.

The fitting's compact footprint (2.9 x 1.25 x 2.95 inches) and featherweight construction (0.11 lbs) make it ideal for tight engine compartments where space is at a premium but performance cannot be compromised. JAZ uses precision-machined aluminum bodies with quality hose barbs or JIC/AN port options to ensure repeatable, leak-free connections in high-pressure and high-temperature environments. This fitting is most beneficial for track-focused builds, high-displacement engines, and custom applications.
