10an to 12an Male Swivel Adapter Fitting

The 10AN to 12AN Male Swivel Adapter Fitting by Aeromotive is a precision hydraulic line connector engineered for high-performance fuel system builds and custom vehicle modifications. This adapter transitions 10 AN male O-ring swivel connections to 12 AN male O-ring ports, making it essential for builders who need flexible plumbing layouts when integrating aftermarket fuel pumps, regulators, or filtration systems. Whether you're tuning a street performance engine or assembling a race-ready fuel delivery system, this fitting eliminates the need for custom hose runs and reduces installation complexity.

Constructed from aluminum and finished in black anodize, the 10AN to 12AN Male Swivel Adapter maintains structural integrity under fuel system pressures while resisting corrosion in engine bay environments. The O-ring swivel design allows directional adjustment during installation without breaking the seal, a critical feature when space is tight or hose angles demand precise alignment. The straight configuration ensures minimal turbulence and pressure drop across the fitting, preserving fuel delivery efficiency and system response in carbureted, EFI, and forced-induction applications alike.

Mechanics and fabricators building custom fuel systems will appreciate the versatility of this adapter when consolidating multiple line sizes on compact engine bay layouts or when transitioning between OEM and aftermarket component standards. Installation is straightforward—thread the fitting hand-tight, then rotate to angle as needed before final wrench-tightening. Compatible with any AN-rated fuel hose and Aeromotive regulators, pumps, or manifolds, this fitting is a must-have for anyone upgrading fuel system capacity or pressure on turbocharged, supercharged, or naturally aspirated builds.
