#6 to 1/2in Pipe Alum Adapter Black

The #6 to 1/2in Pipe Alum Adapter Black (AEROQUIP FCM5013) is a precision straight-thread fitting designed to connect AN (Army-Navy) hydraulic lines to NPT (National Pipe Thread) ports. This adapter serves critical applications in hydraulic systems, fuel lines, and pneumatic setups where different thread standards must interface seamlessly. Commonly found in aerospace, industrial, and automotive hydraulic assemblies, this aluminum adapter eliminates the need for custom fabrication when bridging AN and NPT connections.

Constructed from aluminum with black anodized finish, this fitting provides corrosion resistance while maintaining lightweight durability essential for high-pressure hydraulic environments. The black anodized coating protects against oxidation and wear, ensuring longevity in demanding conditions. The straight design—without elbows or bends—minimizes flow turbulence and pressure drop, making it ideal for systems requiring efficient fluid transfer. Measuring 2.35 x 1.05 x 3.7 inches and weighing just 0.06 lbs, the compact profile accommodates tight installation spaces while the aluminum construction reduces overall system weight without compromising structural integrity or pressure rating.

Technicians, system integrators, and equipment manufacturers rely on this adapter for retrofitting or repairing mixed-thread hydraulic assemblies. It is compatible with standard #6 AN male (0.75-inch diameter) and 1/2-inch NPT male ports, making it suitable for mid-range pressure applications in aircraft fuel systems, industrial hydraulic circuits, and mobile equipment. Installation requires matching the male threads on both ends to their respective female receptacles; thread sealant or PTFE tape is recommended for NPT connections to ensure leak-free operation. Single-unit purchase allows for precise specification matching in repair and custom build applications.
