-6AN Flare to AN Straigh t Cut Thread (7/8-14)

The -6AN Flare to AN Straight Cut Thread (7/8-14) adapter by VIBRANT PERFORMANCE is a precision hydraulic fitting designed for high-performance fuel, oil, and coolant systems in motorsports and automotive applications. This adapter bridges two common industry standards—the 6 AN male flare connection and the 7/8-14 AN straight-thread port—allowing technicians and builders to connect incompatible line sizes and port types without system redesign. Whether you're customizing a fuel system, installing a turbo kit, or integrating aftermarket gauges, this fitting ensures leak-free performance under pressure.

Constructed from aluminum and finished in black anodized coating, the adapter resists corrosion and oxidation while maintaining lightweight properties critical for racing and engine bay applications. The flare end features a 6 AN male connection that seats against a mating 37-degree flare surface, creating a mechanical seal that withstands pressure cycling and vibration without thread-sealant dependency. The straight-thread end is sized 7/8-14, meaning a 7/8-inch diameter with 14 threads per inch—a standard AN port found on fuel blocks, manifolds, and distribution blocks. The anodized finish protects the aluminum from fuel degradation and environmental exposure, ensuring long service life in demanding conditions.

This adapter is ideal for custom fuel system builders, race teams, and engine builders who need to integrate aftermarket fuel rails, surge tanks, and pressure regulators into existing port configurations. Installation requires careful thread alignment and proper torque application to the straight-thread end to prevent leaks and component damage. The compact 3.5-inch length fits tight engine bay layouts without excessive line bending. Compatible with any fuel system using standard -6 AN flare lines and 7/8-14 threaded ports, this VIBRANT PERFORMANCE fitting delivers OEM-equivalent reliability at a fraction of the cost of custom fabrication.
