12AN to 10AN O-Ring Port Adapter Black Male Male

The 12AN to 10AN O-Ring Port Adapter Black Male Male from Redhorse Performance is a crucial fitting designed for custom fuel system builds, turbocharger installations, and high-flow cooling loops requiring line size reduction. This adapter effectively connects larger 12AN hose connections to smaller 10AN ports commonly found on fuel rails, carburetors, and aftermarket fuel pressure regulators.

Machined from aluminum alloy, this male-to-male adapter features precision O-ring ports that eliminate the need for thread sealant tape or Teflon, thus reducing installation time and minimizing contamination risks. The black anodized finish not only resists corrosion but also enhances the aesthetic appeal of modern engine bays while providing protection against oxidation in fuel and coolant environments.

Ideal for carbureted hot rods, EFI conversions, and turbocharged builds, this adapter is versatile and accommodates various fuel system architectures and pressure ratings. Its straightforward installation process involves hand-tightening the male ports into their respective components and ensuring proper O-ring seating before pressurizing the system.
