12AN STR Male Adapter 1in NPT Male Black

The 12AN STR Male Adapter 1in NPT Male Black from REDHORSE PERFORMANCE is a precision hydraulic fitting designed for custom fuel, oil, and coolant line installations in high-performance automotive builds. This straight male adapter bridges AN (Army Navy) flange connections to NPT (National Pipe Thread) ports, making it an essential component for engine bay plumbing when integrating aftermarket fuel systems, turbochargers, nitrous oxide systems, or remote oil filtration setups.

Manufactured from aluminum alloy with a black anodized finish for corrosion resistance and aesthetic durability, the 12AN STR Male Adapter features a 12 AN (1-inch) port diameter paired with a 1-inch NPT male thread on the opposite end. The straight (STR) design eliminates 90-degree or 45-degree bends, reducing turbulence in fuel and oil circuits while maintaining clean aesthetics under the hood.

Mechanics and fabricators rely on this adapter when retrofitting fuel pressure regulators, oil cooler lines, or turbo systems. At just 0.165 lbs, it imposes negligible weight penalty on performance builds, ensuring that your engine bay remains efficient and organized.
