#12flare/#6flare Reducer

The AEROQUIP #12 Flare/#6 Flare Reducer (FCM2165) is a straight-thread adapter fitting designed to connect 12 AN male ports to 6 AN male systems. Constructed from aluminum and finished in blue anodized coating, this reducer maintains pressure integrity across mismatched port sizes while providing a compact, lightweight solution for hydraulic and pneumatic line management in high-performance applications.

The straight-thread design eliminates elbow orientation constraints, simplifying installation in tight spaces where multiple fittings converge. The blue anodized aluminum construction offers corrosion resistance essential in marine, aerospace, and off-road environments where salt spray and moisture exposure accelerates degradation of unprotected metals. At 0.15 lbs and compact dimensions, the adapter adds negligible weight and bulk to systems where space and mass are critical variables—common priorities in racing, military vehicles, and aircraft auxiliary systems.

This fitting serves users who need to downsize hydraulic or pneumatic circuits without replacing entire line runs. Technicians working on fuel systems, brake lines, or pressure-fed equipment often encounter port mismatches when upgrading components or retrofitting assemblies. The AEROQUIP reducer bridges these gaps while maintaining AEROQUIP's reputation for consistent pressure ratings and thread accuracy across their connector catalog.

AN (Army-Navy) standardization ensures this adapter integrates seamlessly with military-spec, aviation, and performance aftermarket systems worldwide. Its proven design has earned adoption across industries where failure is not an option—from combat vehicles to competition vehicles to industrial hydraulic infrastructure.
