-10AN Flare to AN Straig ht Cut Thread (1-1/6-12)

The -10AN Flare to AN Straight Cut Thread (1-1/6-12) adapter from VIBRANT PERFORMANCE is a precision hydraulic and fuel line fitting designed for high-performance automotive, marine, and industrial applications where reliable fluid transfer is critical. This male flare-to-male O-ring adapter bridges two different AN (Army-Navy) standard port configurations, enabling seamless integration between legacy flare-style connections and modern O-ring face seal systems. Builders and technicians rely on these adapters when upgrading or customizing fuel systems, brake lines, and coolant circuits that demand leak-free performance under pressure.

Constructed from lightweight aluminum and finished in black anodized coating, this fitting resists corrosion while maintaining a clean aesthetic in engine bays and exposed installations. The straight-thread design eliminates elbow configurations, reducing overall assembly footprint and simplifying plumbing layouts in tight spaces. The 10 AN male flare port connects to standard 37-degree JIC flare fittings, while the 12 AN male O-ring port seats against an ISO 6149 or DIN 3852-A O-ring groove—a dual-standard approach that maximizes compatibility across OEM and aftermarket components. At just 0.09 lbs, the compact 3.05 × 1.3 × 3.55-inch form factor fits easily into congested engine compartments without adding measurable weight or bulk.

This adapter is ideal for custom fuel system builds, intercooler circuit conversions, and restoration projects where port sizes or thread pitches must be harmonized across multiple components. Whether upgrading a vintage carburetor fuel line to modern injection specs or adapting a turbo coolant circuit to a different manifold standard, the -10AN Flare to AN Straight Cut Thread fitting delivers the versatility and durability expected from VIBRANT PERFORMANCE's engineered product line. Proper installation requires torque-wrench tightening to prevent over-torque damage and ensuring O-ring seals seat correctly—a straightforward procedure for anyone with basic hose and fitting experience.
