-6AN Flare to AN Straigh t Cut Thread (3/4-16)

The -6AN Flare to AN Straight Cut Thread (3/4-16) adapter by Vibrant Performance is a precision hydraulic fitting engineered for high-pressure fluid line connections in automotive and industrial applications. This adapter bridges 6 AN male flare connections to 3/4-16 straight thread ports, making it essential for custom fuel systems, brake lines, transmission coolers, and power steering installations where reliable, leak-free connections are non-negotiable. Technicians and performance enthusiasts rely on AN fittings to handle fluctuating pressures and vibration without failure.

Constructed from aluminum with a durable black anodized finish, this adapter resists corrosion and oxidation while maintaining strength under demanding conditions. The 6 AN male flare end uses a 37-degree flare sealing surface—the industry standard for motorsports and OEM hydraulic systems—while the 3/4-16 straight cut thread port accepts o-ring face seal (ORFS) or traditional NPT connections depending on your system configuration. Black anodizing provides both aesthetic appeal and protective coating against harsh underhood environments, fuel contact, and temperature cycling.

Performance shops, race teams, and DIY builders benefit most from this adapter when upgrading fuel delivery systems, cooling circuits, or hydraulic brake lines on street rods, race cars, and marine engines. Installation requires standard hydraulic wrenches and basic mechanical skill; ensure the flare end is tightened to specification while the threaded port is sealed with appropriate sealant or o-ring depending on your component interface. Weighing only 0.04 lbs, it adds negligible mass while delivering proven reliability across thousands of build applications.
