-12 Male AN Flare to -16AN Male ORB Adapter

The -12 Male AN Flare to -16AN Male ORB Adapter from Vibrant Performance is an essential fitting for fuel and fluid system modifications on high-performance vehicles. This adapter bridges two critical hydraulic standards—AN flare and ORB (O-ring boss) connections—allowing seamless integration when upgrading fuel systems, coolant lines, or brake circuits on turbocharged, supercharged, and naturally aspirated platforms.

Whether you're custom-building a fuel rail assembly or retrofitting late-model fuel delivery components into a classic muscle car, this adapter eliminates the need for costly custom fabrication or incompatible workarounds. The adapter features a -12 AN male flare inlet that accepts standard AN push-lock fittings and braided hose assemblies, while the -16 AN male ORB port threads directly into manifold ports and component blocks without leakage risk. The ORB design creates a face-seal connection that outperforms traditional NPT threads under high fuel pressure and thermal cycling, critical for ethanol-blend fuels and sustained boost conditions.

Vibrant Performance's manufacturing tolerances ensure consistent thread fit and flare compatibility across all major fuel injection control systems and aftermarket fuel management platforms. This adapter is ideal for engine builders, tuners, and enthusiasts executing fuel system upgrades on LS-series, Coyote, Gen3 Hemi, and import turbocharged platforms where OEM fittings are often inadequate.
