Male Adapter Fitting #6 x 18mm x 1.5 FI

The FRAGOLA Male Adapter Fitting #6 x 18mm x 1.5 FI is a precision hose and fuel line adapter designed for custom fuel system builds and turbo plumbing. This fitting bridges two different connection standards—adapting a -6 AN (JIC) port to an 18mm x 1.5 metric port—making it essential for fabricators and engine builders working with imported components or modern OEM systems alongside traditional AN-based fuel and coolant circuits.

Manufactured by FRAGOLA, a trusted name in performance fuel system components, this male adapter features precision machining to ensure leak-free connections under pressure and vibration. The -6 AN side is compatible with standard automotive hose crimps and swages, while the 18mm x 1.5 metric port provides compatibility with European and metric-threaded components common in modern fuel pumps, pressure regulators, and turbo intercooler systems.

Weighing just 0.04 lbs and measuring 3.45 x 1 x 4.55 inches, the compact form factor allows installation in tight engine bays without sacrificing durability or flow capacity. This adapter is ideal for engine swap projects, turbocharger plumbing upgrades, and hybrid applications, ensuring seamless integration of various fuel system components.
