3/8in female Pipe To #6 Flare

The AEROQUIP 3/8in Female Pipe to #6 Flare adapter is a steel straight-fitting connector designed to bridge NPT (National Pipe Thread) female ports to AN (Army-Navy) male flare connections. This FCM2727 adapter serves critical functions in hydraulic systems, fuel lines, and pneumatic applications where reliable pressure-sealed connections are essential to preventing leaks and maintaining system integrity.

The adapter features a zinc oxide finish that resists corrosion in harsh environments, making it suitable for marine, industrial, and outdoor equipment applications where moisture and salt air pose ongoing threats to uncoated fasteners. The 3/8-inch NPT female port accepts standard pipe thread connections, while the #6 AN male flare end conforms to military-standard flare specifications, ensuring compatibility across a wide range of OEM and aftermarket hydraulic and fuel system components. At 0.15 lbs, the compact lightweight design minimizes system weight without compromising durability or pressure rating.

This adapter is used in fluid power systems, mobile equipment, aerospace support applications, and custom hydraulic installations where mixed thread standards require a dependable transition fitting. Technicians and mechanics rely on AEROQUIP adapters to simplify installations that would otherwise require thread conversion sleeves or multiple intermediate fittings. The straight configuration eliminates unnecessary bends and pressure drop, supporting optimal system performance in applications ranging from agricultural machinery to tactical vehicle support systems.

Steel construction with proven zinc oxide protective coating ensures long service life in fluctuating temperature and moisture conditions. This SKU AERFCM2727 is the single-unit offering, suitable for retrofit repairs, replacement work, or OEM assembly applications where precise thread-to-flare adaptation is required.
