Female to Male Reducer A dapter Female -10 to -6

The Vibrant Performance Female to Male Reducer Adapter (Female -10 to -6, Part Number 10834) is a straight-fitting AN adapter engineered for hydraulic and pneumatic systems where size reduction between circuit segments is required. This aluminum adapter with black anodized finish steps down from a -10 AN female port to a -6 AN male connection, maintaining system integrity while enabling compatibility between different hose and component sizes in performance fuel, coolant, and pressure applications.

Constructed from lightweight aluminum and finished in black anodized coating, this adapter provides corrosion resistance and durability in demanding engine bay environments. The straight-passage design eliminates flow restrictions at the transition point, critical for maintaining pressure ratings and system reliability in both street and racing applications. Weighing just 0.09 lbs, the compact 2.85 x 1.4 x 3.9-inch footprint integrates seamlessly into tight spaces where direct hose connections aren't feasible. The -10 to -6 step-down ratio is a common size transition in fuel system tuning, intercooler piping, and custom cooling circuits where existing components use different port standards.

This adapter suits builders and technicians upgrading fuel delivery systems, installing aftermarket supercharger or turbocharger plumbing, or retrofitting hydraulic cooling lines. AN fittings are the industry standard in motorsports because of their leak-free seals, pressure ratings, and reusability. The -10 to -6 reducer is frequently used when transitioning from larger trunk-mounted fuel cells or coolers to standard engine-bay fuel lines, or when adapting modern performance components to legacy platforms with different port sizes.

Vibrant Performance is recognized within the automotive aftermarket for manufacturing precision-engineered AN adapters and hose fittings. Each reducer is manufactured to SAE and ISO AN standards, ensuring proper thread pitch, port geometry, and pressure compatibility across a wide range of high-performance fuel, coolant, and brake system applications. Stock this adapter for your next custom fuel system build or cooling circuit upgrade.
