8AN to M18x1.5 AN/JIC Flare Inverted

The REDHORSE PERFORMANCE 8AN to M18x1.5 AN/JIC Flare Inverted adapter is an essential hydraulic fitting designed for high-performance fuel and coolant line systems in modified vehicles. This adapter effectively connects European metric threaded ports (M18x1.5) with North American AN/JIC flared line connections (8AN), making it a valuable component for automotive enthusiasts and mechanics.

Constructed with precision, this inverted flare fitting features industry-standard JIC 37-degree cone geometry on the 8AN side, paired with a meticulously machined M18x1.5 metric male thread on the opposite end. The inverted design allows the flare seat to face outward, which helps prevent cross-threading and ensures a leak-free seal under the pressure cycles typical of fuel injection and coolant systems.

Ideal for engine swaps, LS conversions in foreign chassis, and custom fuel system builds, this adapter provides a direct and reliable solution that eliminates costly redesigns and fabrication delays. Mechanics and fabricators appreciate REDHORSE fittings for their durability under vibration and thermal cycling, making them a trusted choice in motorsports plumbing.
