8an Male to 3/8 Tube Adapter Fitting

The EARLS 8AN Male to 3/8 Tube Adapter Fitting (AT165086ERL) is a precision-engineered hydraulic and fuel system connector designed for custom automotive builds where space constraints and pressure ratings demand reliable thread-to-tube transitions. Built for serious enthusiasts who modify high-performance fuel delivery systems, turbo setups, and hydraulic cooling circuits, this adapter bridges the gap between AN fittings and compression tube standards.

Manufactured by EARLS, a recognized leader in performance fuel system components, this fitting features male AN threads on one end and a 3/8-inch tube compression fitting on the other. The aluminum construction keeps weight minimal—approximately 0.06 lbs—critical for vehicles where every ounce matters, while EARLS' proven manufacturing standards ensure the fitting handles fuel system pressures and vibration cycles without degradation.

The compact 2.3 x 1.2 x 2.7-inch envelope fits tight engine compartments, and the precision-machined surfaces guarantee a secure seal when paired with proper -8AN hose or tubing and corresponding compression fittings. This dual-standard design eliminates the need for multiple adapters in complex fuel delivery or coolant bypass configurations, making it ideal for mechanics and fabricators working on EFI fuel rail swaps and custom turbo feed lines.
