Reducer AN Male -6 to -10

The Reducer AN Male -6 to -10 from ALLSTAR PERFORMANCE is a precision hydraulic adapter designed for fuel, coolant, and brake line systems in high-performance and custom automotive builds. This fitting is essential for mechanics and fabricators who need to step down from larger -6 AN (3/8") hose to smaller -10 AN (5/8") components, making it ideal for engine bay plumbing where space constraints or system pressure requirements demand a gradual diameter transition.

Manufactured by ALLSTAR PERFORMANCE, this male-to-male reducer features precision machining to handle high-pressure applications common in fuel injection systems and custom cooling circuits. The AN (Army-Navy) standard threads ensure compatibility across all modern performance components, and the tapered design creates a smooth flow path that minimizes turbulence and pressure loss.

Professional mechanics, fabricators, and serious automotive enthusiasts benefit most from this reducer, which ensures leak-free, reliable connections without the need for incompatible adapters. At just 0.07 lbs and compact dimensions of 2.3 x 1.2 x 4.05 inches, it installs easily in tight engine compartments without adding bulk.
