#6 Male To #8 O-Ring Bos

The XRP-XTREME RACING PROD. #6 Male To #8 O-Ring Boss adapter is a straight AN fitting designed to connect hydraulic lines, fuel systems, and pressurized fluid applications across different port sizes. This aluminum adapter transitions from a #6 AN male port to an #8 AN male O-ring boss configuration, enabling compatibility between mismatched line sizes in high-performance marine, automotive, and racing systems where seal integrity and pressure rating are critical.

The straight-thread design eliminates unnecessary bends in plumbing runs, reducing pressure losses and simplifying installation in tight engine compartments. Black anodized aluminum construction provides corrosion resistance essential in saltwater marine environments while keeping weight minimal. The O-ring boss design (standard for marine and high-performance applications) creates a metal-to-metal seal when mated with compatible fittings, offering superior reliability over traditional NPT threads in systems that cycle pressure or experience vibration. AN-rated fittings are engineered to exacting industry standards and work under demanding conditions where fluid containment is non-negotiable.

This adapter serves marine engine builds, offshore racing applications, high-performance fuel systems, and hydraulic control setups where line routing requires size transitions between components. Weekend fishermen upgrading cooling or fuel systems and serious offshore competitors optimizing engine bay plumbing both rely on properly sized AN fittings to prevent leaks under load. The black anodized finish resists the corrosive effects of salt spray and aggressive cleaning protocols used in marine maintenance, extending service life compared to bare aluminum. Individual unit sold; sizing both ends of your system correctly before ordering ensures leak-free assembly.
