#6 Male to 14mm x 1.5 Adapter

The #6 Male to 14mm x 1.5 Adapter by EARLS is a precision hydraulic and pneumatic fitting designed to bridge incompatible port sizes in fluid transfer systems. This straight adapter connects a #6 AN (Army-Navy) male port to a 14mm x 1.50 male metric port, making it essential for custom fuel systems, cooling circuits, and brake line configurations where metric and AN standards must interface. Whether you're building a high-performance engine bay, restoring a classic vehicle, or engineering a specialized fluid system, this adapter eliminates the need for costly custom fabrication or system redesign.

Constructed from aluminum and finished in blue anodize, the #6 Male to 14mm x 1.5 Adapter provides excellent corrosion resistance while maintaining lightweight durability—critical traits in motorsport and aerospace applications. The anodized finish protects against oxidation and wear, extending service life in both engine bay heat and outdoor storage conditions. The straight-port design minimizes turbulence and pressure drop, ensuring consistent flow rates and system reliability. Precision machining ensures thread integrity on both the #6 AN and 14mm x 1.50 male ends, preventing leaks and maintaining safe operating pressures in demanding fluid systems.

This adapter is ideal for fabricators, performance technicians, and enthusiasts who work across mixed metric and AN standards—common in European-sourced components integrated into American-spec platforms. Installation is straightforward: thread the #6 AN end into existing AN ports and the 14mm x 1.50 end into metric fittings, using appropriate thread sealant for fuel or coolant applications. Weighing just 0.03 lbs with compact dimensions (1.4 x 0.85 x 2.95 inches), it fits tight engine bays and custom plumbing layouts without bulk. Verify thread pitch and port orientation before assembly to ensure correct flow direction and leak-free operation in your specific system.
