Flare Reducer Adapter 10an to 6an

The EARLS Flare Reducer Adapter 10AN to 6AN is a precision straight-fit hose adapter engineered to bridge mismatched AN port sizes in high-pressure hydraulic and fuel systems. This aluminum fitting transitions a 10 AN female port to a 6 AN male connection, making it essential for custom fuel line routing, brake system modifications, and motorsport applications where port compatibility is critical.

Constructed from aluminum and finished in black anodize, this adapter resists oxidation and corrosion in demanding environments. The straight configuration eliminates flow restriction and simplifies plumbing in tight engine bays. AN fittings are industry-standard in racing, restoration, and performance vehicle builds because their flare design creates a sealed connection without requiring thread sealant—a critical advantage in high-vibration or high-temperature contexts where leaks can cause catastrophic failure.

This adapter suits fabricators, engine builders, and motorsport technicians who need reliable port reduction without compromise. It's commonly used in fuel system upgrades, hydraulic brake conversions, and custom plumbing where existing hose sizes don't align with available manifold ports. The compact 1.6 × 1.05 × 2.95 inch footprint allows installation in confined spaces typical of modern engine compartments and chassis builds.

AN fittings remain the gold standard in performance and specialty automotive applications because they deliver leak-free operation under sustained pressure and thermal cycling. An EARLS adapter backed by verified specifications ensures your system meets OEM or custom performance standards without improvisation.
