AN Flare To ORB Adapter 3/4-16 (-8) to -6

The AN Flare To ORB Adapter 3/4-16 (-8) to -6 is a precision hydraulic and fuel line fitting adapter engineered for high-performance automotive and racing applications. This straight adapter bridges two different AN connection standards, enabling seamless integration when upgrading fuel systems, cooling circuits, or brake lines where mismatched port sizes exist. Fabricated by ALLSTAR PERFORMANCE, a trusted name in motorsports plumbing solutions, this adapter eliminates the need for costly custom fabrication or system redesigns.

Constructed from aluminum and finished in black anodized coating, the adapter provides excellent corrosion resistance while maintaining a lightweight profile—critical in competition vehicles where every ounce counts. The flared end (3/4-16, equivalent to -8 AN) mates to the O-ring boss end (-6 AN) using industry-standard aerospace specifications, ensuring leak-free performance under pressure cycling and thermal stress. Black anodized aluminum resists oxidation in harsh underhood environments and presents a professional appearance in custom engine bays. The straight configuration allows direct, unobstructed flow with minimal turbulence, ideal for fuel delivery, coolant transfer, or transmission cooler circuits.

This adapter benefits engine builders, restoration specialists, and performance tuners converting legacy or custom fuel and cooling systems to modern AN standards. It is commonly used during fuel cell installations, carbureted-to-EFI conversions, and bracket or manifold upgrades where port sizes differ. Installation requires only standard wrenches and basic plumbing knowledge; ALLSTAR fittings are designed for straightforward assembly without specialized tools. Verify both your source and destination port thread sizes and connection types (flare versus O-ring boss) before ordering to ensure proper fit and sealing integrity.
