Male Adapter Fitting #6 x 14mm x 1.5 FI Black

The Male Adapter Fitting #6 x 14mm x 1.5 FI Black from FRAGOLA is a precision hydraulic and fuel system connector engineered for custom automotive builds, engine swaps, and high-performance fuel line modifications. This adapter serves as a critical transition piece in fuel systems, cooling circuits, and brake line applications where you need to bridge between #6 AN hose (0.375" ID) and a 14mm x 1.5 metric female port. Whether you're fabricating a fuel system for a carbureted swap, upgrading to modern EFI plumbing, or designing a custom cooling loop, this fitting ensures leak-free connections and reliable performance under pressure.

Built to FRAGOLA's OEM standards, this male adapter features a compact form factor (1.45 x 1.15 x 4.15 inches) and weighs just 0.03 lbs, making it ideal for tight engine bay installations where space is at a premium. The #6 AN port connects to standard AN hose via a 37-degree JIC flare, delivering maximum flow capacity without sacrificing durability, while the 14mm x 1.5 metric female inlet accommodates OEM or aftermarket metric manifold ports. The black anodized finish provides corrosion resistance and a professional appearance, protecting against fuel degradation and oxidation in both street and track environments. Precision machining ensures the sealing surfaces meet exacting tolerances, eliminating weeping connections that can plague poorly-fitted adapters.

This fitting is essential for custom fuel system builders, engine swap specialists, and vintage car restorationists who need to interface modern fuel delivery or cooling systems with metric-threaded engine blocks or aluminum components. Mechanics performing LS engine swaps, carburetor conversions to EFI, or custom high-flow fuel rails will find this adapter indispensable for creating clean, reliable connections without custom fabrication. Proper installation requires hand-tightening the AN hose end to the fitting, then using a wrench to secure the metric female port to your manifold or component—always use appropriate thread sealant or PTFE tape on metric ports to ensure zero fuel leakage under operating pressure.
