The EARLS 8 AN Male to 3/8 Tube Adapter Fitting (AT165086ERL) is a precision straight-tube adapter engineered for high-pressure fluid systems in racing, performance, and industrial applications. This AN-to-tube conversion fitting maintains system integrity by providing a leak-free connection between AN-spec hose ends and 3/8-inch tubing, a critical junction point in fuel, oil, coolant, and brake line circuits where pressure consistency is non-negotiable.
Constructed from aluminum and finished in black anodizing, this adapter resists corrosion while maintaining the low weight profile essential in performance builds. The 8 AN male thread (standard 1.1875-16 UN) engages securely with AN hose fittings, while the 3/8-inch tube end accepts standard seamless tubing through a flared or compression fitting interface. The straight configuration eliminates deflection and turbulence, preserving flow efficiency across fuel injection systems, turbocharger feed lines, and transmission cooler circuits. Weighing just 0.06 lbs, it adds negligible mass while delivering the reliability required in temperature-cycled and high-vibration environments.
Buyers seeking AN to 3/8 tube adapter fittings—whether for street performance, drag racing, marine systems, or heavy equipment maintenance—depend on EARLS fittings for their precision engineering and proven durability. This adapter is sold as a single unit and integrates seamlessly into existing AN-based plumbing schemes where tubing transitions are necessary. The black anodized finish provides visual distinction while protecting against oxidation in engine bays and exposed mounting locations.
AN (Army-Navy) fittings have been the industry standard for high-performance systems for decades because of their repeatable, zero-leak design. The 8 AN size carries up to 3,000 PSI in typical applications, making it suitable for modern fuel-injected engines, supercharged systems, and pressurized cooling circuits. When reliability and compatibility are critical, EARLS fittings deliver the precision fit and durability that professionals specify.
