Swivel Adapter Fitting - 8an to 10an

The Aeromotive Swivel Adapter Fitting - 8AN to 10AN (Part No. 15638) is a precision-engineered hydraulic adapter designed to connect lines with different port sizes in high-flow fuel and fluid delivery systems. Constructed from aluminum and finished in black anodize, this straight swivel adapter features 8 AN male O-ring on one end and 10 AN male O-ring on the other, enabling secure, leak-free transitions between differing hose sizes without additional fittings or complexity.

The swivel design allows rotational freedom during installation and removal, reducing stress on connected lines and hose assemblies during service and maintenance. Aluminum construction provides corrosion resistance and lightweight performance critical in motorsport and aerospace applications where weight and durability are equally important. The O-ring face seal (ORF) design ensures positive sealing under pressure without requiring additional sealant tape, delivering reliable performance in fuel systems, coolant circuits, and pressurized fluid transfer applications. The black anodized finish protects against oxidation while maintaining a professional appearance on visible installations.

This adapter is essential for custom fuel system builds, engine swaps, and retrofits where stock hose configurations don't match available ports. Users building high-performance fuel delivery systems, competition vehicles, or hydraulic circuits benefit from the flexibility this step-down adapter provides. The compact dimensions (2.65 x 1.25 x 3.75 inches) and minimal weight (0.1 lbs) make it suitable for space-constrained engine bays and systems where every ounce matters. Aeromotive fittings are engineered to withstand the demands of continuous-flow fuel pumps and regulated pressure systems, making this adapter a reliable choice for serious enthusiasts and professional installers.
