Steel Fitting Inverted Flare -6 to 5/18-18

The Steel Fitting Inverted Flare -6 to 5/8-18 is a precision hydraulic and pneumatic adapter designed to connect systems requiring reliable, leak-free transitions between 6 AN male ports and 5/8-18 inverted flare male connections. This adapter is essential for fluid power applications across automotive, industrial, and aerospace environments where adapting between different flare standards is critical to system integrity and performance.

Manufactured by AEROQUIP under model FCM2964, this steel fitting features a zinc oxide finish that provides corrosion resistance and durability in demanding conditions. The straight-configuration design minimizes turbulence and pressure drop while the inverted flare sealing surface creates a compression fit that maintains system pressure without the need for thread sealant tape. Steel construction ensures exceptional strength and thermal stability, making it suitable for high-pressure applications and temperature fluctuations common in industrial hydraulic systems.

Technicians and system integrators benefit from this adapter when retrofitting legacy equipment or combining components from different manufacturers with incompatible port standards. Installation is straightforward—simply hand-tighten the 5/8-18 connection before using a wrench to secure the final quarter turn, ensuring proper flare seating without over-torquing. Weighing just 0.08 pounds with compact dimensions of 2.3 x 1.1 x 3.7 inches, this fitting integrates easily into space-constrained assemblies while maintaining full structural integrity under rated pressure loads.
