The 6AN to 10AN O-Ring Port Adapter Black Male Male from REDHORSE PERFORMANCE is a precision hydraulic and fuel line fitting designed for high-performance automotive and motorsport applications where reliable, leak-free connections are critical. This straight adapter enables seamless integration between 6 AN (JIC -6) and 10 AN (JIC -10) male ports, making it essential for custom fuel systems, turbo setups, supercharger installations, and high-pressure hydraulic circuits. Whether you're building a race-ready engine bay or upgrading a street performance vehicle, this adapter bridges incompatible line sizes with confidence and durability.

Constructed from aluminum and finished in black anodizing, this 920 Series fitting delivers both corrosion resistance and a professional appearance that complements any engine compartment aesthetic. The o-ring seal design ensures superior leak prevention compared to traditional flare fittings, particularly under vibration and pressure cycling common in performance driving. The male-to-male configuration allows for flexible plumbing layouts, and the straight geometry minimizes turbulence and pressure drop in fuel and fluid delivery systems. Black anodized aluminum construction provides lightweight durability without sacrificing strength—critical for applications where weight savings and reliability go hand in hand.

This adapter is ideal for fabricators, engine builders, and enthusiasts upgrading fuel rails, turbo supply lines, or intercooler systems where port sizes don't match OEM specifications. The compact 2.8 x 1.15 x 3.85-inch footprint fits tight engine bays without requiring extensive rerouting, and the o-ring port design is compatible with standard AN hose fittings and port blocks found across professional motorsport and automotive aftermarket segments. Installation is straightforward—simply thread the male ends into their respective ports using a wrench, confirm o-ring seating, and torque per manufacturer specifications for a dependable, vibration-resistant connection.
