AN Flare To ORB Adapter 3/4-16 (-8) to -10

The AN Flare To ORB Adapter 3/4-16 (-8) to -10 from ALLSTAR PERFORMANCE is a precision hydraulic and pneumatic fitting designed to bridge different AN (Army-Navy) port standards in high-pressure fluid systems. This straight adapter converts -8 AN male flare ports to -10 AN male O-ring boss (ORB) connections, making it essential for custom fuel systems, brake lines, transmission coolers, and aftermarket racing applications where port compatibility must be reconciled. Whether you're building a street rod fuel system or upgrading a performance engine bay, this adapter eliminates the need for complete line replacement by allowing mismatched fittings to work together safely and reliably.

Constructed from aluminum and finished in black anodize, the AN Flare To ORB Adapter 3/4-16 (-8) to -10 combines corrosion resistance with lightweight durability. The 3/4-16 thread specification accommodates the adapter body's mounting interface, while the flare-to-ORB conversion allows seamless integration between traditional AN flare connections and modern O-ring boss ports that provide superior leak prevention under vibration and pressure cycling. Black anodizing protects against oxidation and provides aesthetic consistency across engine bay installations. Weighing just 0.07 lbs, the compact 2.2 x 1.4 x 4.1-inch form factor fits tight spaces without imposing bulk or requiring clearance modifications.

This adapter benefits custom builders, performance shops, and enthusiasts who demand system flexibility when plumbing fuel, oil, coolant, or brake circuits. It is ideal for applications where existing -8 AN flare lines must interface with newer -10 ORB equipped components—common in modern EFI fuel systems, turbo installations, and transmission upgrades. Proper installation requires verification of system pressure ratings and torque specifications to ensure thread integrity; the straight design allows direct inline mounting without additional angles or bends.
