Flare Reducer Adapter 10an to 8an

The Flare Reducer Adapter 10AN to 8AN from EARLS is a precision-engineered fitting designed for custom fuel, coolant, and hydraulic line systems where port size transitions are necessary. This straight adapter bridges the gap between 10 AN (AN10) female connections and 8 AN (AN8) male ports, making it essential for builders who need flexible routing without compromising flow integrity. Whether you're fabricating a high-performance fuel system, upgrading cooling lines on a modified engine, or integrating aftermarket hydraulic components, this adapter eliminates the need for multiple fittings while maintaining a clean, professional installation.

Machined from aluminum and finished in black anodized coating, the Flare Reducer Adapter delivers corrosion resistance and durability in demanding under-hood and under-car environments. The AN flare standard (JIC 37-degree flare) ensures leak-free seals under pressure when paired with compatible hose and fittings. EARLS' manufacturing tolerances guarantee a straight-through design that minimizes turbulence and pressure loss, critical when flowing fuel to high-volume fuel pumps or coolant through performance radiators. The compact 1.45 x 1.15 x 2.65-inch footprint and lightweight 0.06-pound design make it ideal for tight engine bays where space and weight matter.

Professional fabricators, street performance builders, and restoration specialists rely on EARLS adapters for reliability when downsizing or upsizing line diameters. This fitting suits applications ranging from carbureted fuel systems to modern turbocharged setups, LS swaps, and vintage engine conversions where original AN port sizes don't match available hose. Installation requires only standard AN wrenches and proper torque application to the flare nut—no special tools needed. Verify your existing line sizes and AN specifications before ordering to ensure this 10AN-to-8AN configuration matches your system's inlet and outlet requirements.
