#12 to #8 O-Ring Male Adapter Fitting

The #12 to #8 O-Ring Male Adapter Fitting from MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS is a precision straight adapter designed to bridge AN-12 male ports to AN-8 male connections in high-performance fuel systems. Constructed from aerospace-grade aluminum and finished in purple anodize, this MP-3023 adapter delivers reliable compatibility and corrosion resistance in demanding engine bay environments where fuel line routing requires size transitions.

The O-ring face seal design ensures leak-free operation under pressure, a critical requirement in fuel delivery systems where even minor weeping can compromise performance and create safety hazards. The aluminum construction keeps weight minimal—essential in race and high-performance applications—while the purple anodize provides durable surface protection against fuel contamination and thermal cycling. This straight-port configuration allows direct line-to-fitting connection without sharp bends, simplifying installation and reducing turbulence in fuel flow paths.

The adapter serves builders and technicians working with performance fuel systems where AN-rated fittings are standard. Typical applications include fuel rail upgrades, custom fuel line routing in engine swaps, and competitive motorsports where standardized quick-connect fittings eliminate guesswork. The AN fitting ecosystem—governed by industry standards—ensures compatibility across aftermarket fuel delivery components from reputable manufacturers, making this adapter a reliable solution for system integration.

MAGNAFUEL/MAGNAFLOW Fuel Systems specializes in precision fuel delivery components trusted in street performance and professional racing environments. This adapter represents the attention to detail expected from the brand—quality materials, proven sealing technology, and compatibility with industry-standard specifications that serious builders depend on.
