Female -6AN Flare to Male -6AN ORB Fitting

The female -6AN flare to male -6AN ORB fitting is a precision hydraulic adapter designed for high-performance fuel, coolant, and fluid transfer systems in racing, marine, and industrial applications. This straight-configuration fitting bridges two common connection standards—AN flare threads on one end and O-ring boss (ORB) on the other—making it essential for builders who need to integrate components from different manufacturers or upgrade existing plumbing without complete system redesign. Its compact, lightweight design fits snugly into confined engine bays and complex manifold layouts.

Manufactured from aluminum and finished in durable black anodize, this adapter resists corrosion and heat stress while maintaining tight tolerances critical to leak-free operation under pressure. The -6AN size handles flows up to 80+ gallons per minute at typical racing pressures, making it suitable for fuel injection systems, power steering circuits, and coolant lines. The female flare end accepts standard 37-degree flare hose fittings, while the male ORB port threads directly into SAE-standard O-ring boss receivers, eliminating the need for additional sealing tape or compound on the ORB side.

This fitting is ideal for engine builders, custom fabricators, and performance enthusiasts upgrading fuel systems, turbo boost lines, or transmission coolers. It works across gasoline and diesel engines, and is compatible with any system using standard -6AN hose or hardline with flare fittings. Installation is straightforward: flare fittings hand-tighten easily, while the ORB end threads into the receiving port with a wrench, requiring no special tools or alignment procedures.
