6AN to M10x1.0 AN/JIC Flare Inverted

The 6AN to M10x1.0 AN/JIC Flare Inverted fitting from REDHORSE PERFORMANCE is a precision hydraulic adapter engineered for custom fuel, oil, and coolant line systems in high-performance vehicles and engine builds. This inverted JIC flare connector bridges the gap between AN-standard 6-size tubing and metric M10x1.0 threaded ports, making it essential for modern swaps, turbo installations, and fuel system upgrades where OEM components use metric ports. Built for reliability in demanding automotive applications, this fitting eliminates the guesswork when integrating aftermarket fuel rails, oil coolers, or turbocharger feed lines into vehicles with mixed fastener standards.

REDHORSE PERFORMANCE fittings feature precision-machined bodies and inverted flare cone geometry that locks onto 37-degree JIC flare tubing for leak-free, vibration-resistant connections under high pressure and temperature cycling. The inverted design allows the flare nut to seat against the fitting body itself rather than relying solely on the male port, reducing stress on metric threads and improving longevity in turbocharged and supercharged applications. The M10x1.0 metric port is ISO-standard, ensuring compatibility with import performance platforms, LS-swapped vehicles, and modern fuel injection systems where metric fittings dominate port sizing and thread pitch specifications.

Mechanics and fabricators choosing the 6AN to M10x1.0 AN/JIC Flare Inverted fitting will find it indispensable for fuel system restorations, custom EFI conversions, and engine swaps where adapting vintage AN-standard braided hose to modern metric injection points is non-negotiable. This fitting handles sustained pressure from mechanical fuel pumps, electric in-tank systems, and forced-induction fuel delivery without weeping or failure, provided installation includes proper flare quality and torque specs. Compact at 2.75 inches in length, it fits tight engine bays and custom fab environments, making it a go-to choice for builders who demand OEM-level reliability from aftermarket systems.
