AN to Metric Fitting -8AN to M20 x 1.5

The AN to Metric Fitting -8AN to M20 x 1.5 by Vibrant Performance is an essential component for those integrating performance fuel systems, turbo oil lines, or custom cooling loops that require compatibility between AN (Army-Navy) fittings and metric components. This adapter is particularly useful for engine builders and tuners who face challenges when working with mixed-specification platforms.

Constructed with precision engineering, this fitting translates the -8AN nominal diameter (exactly 0.5 inches) into a metric M20 x 1.5 male thread, ensuring leak-free sealed connections in fuel, oil, and coolant circuits where pressure integrity is critical. The M20 x 1.5 pitch provides superior holding power against vibration, making it ideal for applications near engine blocks or turbo housings that experience constant thermal expansion.

This adapter is beneficial for fabricators upgrading fuel delivery on turbocharged platforms, mechanics retrofitting metric-port blocks with AN-standard braided hose assemblies, and tuners integrating external oil coolers or catch can systems. Its reliability under high pressure and thermal cycling makes it a preferred choice for those seeking durable and effective solutions in their automotive projects.
