Straight Adapter FItting ; Size: -6 AN x 3/8in NP

The Vibrant Performance Straight Adapter Fitting in -6 AN x 3/8in NPT (part number 10222) is a precision aluminum adapter designed to bridge connections between -6 AN male ports and 3/8-inch NPT male threads. This straight adapter fitting is essential in high-pressure fluid systems where reliable, leak-free connections between different thread standards are critical. Black anodized aluminum construction provides corrosion resistance and durability in both engine bay and external environments, making it suitable for performance fuel, oil, coolant, and pneumatic applications.

The -6 AN (SAE standard) to 3/8 NPT (National Pipe Thread) conversion enables integration between modern aftermarket fuel systems and factory NPT-threaded components. Vibrant Performance adapters are manufactured to OEM tolerances, ensuring proper sealing without thread sealant tape—a critical feature in systems using mechanical seals or O-rings. The straight configuration minimizes flow turbulence compared to 90-degree fittings and simplifies plumbing layouts in compact engine compartments. At just 0.04 lbs, this adapter adds negligible weight while delivering the thread compatibility required for precision fuel system builds, turbo installations, and custom cooling applications.

This adapter is ideal for builders upgrading fuel injectors, swapping fuel pressure regulators, or installing aftermarket oil coolers and turbo feed lines where NPT-threaded factory ports must interface with AN-standard hose fittings. The black anodized finish resists salt spray and fuel oxidation, making it reliable for both street applications and track environments. Vibrant Performance has established itself in the performance automotive market for precision hose and adapter solutions that meet professional fabrication standards.
