1/8in female Pipe To #4 Flare

The AEROQUIP 1/8 inch female pipe to #4 flare adapter is a precision straight-thread fitting designed to connect NPT female ports to AN male flare systems. Manufactured from steel with zinc oxide coating, this adapter delivers reliable pressure containment in hydraulic and pneumatic applications where mixed thread standards must interface seamlessly. The compact design and proven AEROQUIP engineering make this fitting essential for systems requiring robust fluid power connections.

The 1/8 inch NPT female connection accepts standard pipe thread ports commonly found in industrial and mobile equipment manifolds, while the #4 AN male flare end mates with -4 AN hose assemblies and components throughout aerospace, automotive, and hydraulic system platforms. Steel construction provides strength under rated pressure cycles, and zinc oxide plating resists corrosion in harsh operating environments. The straight geometry eliminates flow restrictions and simplifies installation in tight spaces where elbow fittings cannot fit.

This adapter serves technicians, engineers, and maintenance crews rebuilding or modifying fluid power systems where legacy NPT-threaded components must connect to modern AN-standard hose networks. Aircraft maintenance shops, hydraulic repair facilities, and mobile equipment manufacturers rely on AEROQUIP adapters to maintain system integrity while bridging incompatible thread types. Field technicians value the simplicity of a single verified fitting over custom solutions, reducing downtime and ensuring compliance with equipment specifications.

AEROQUIP maintains its reputation as an original equipment and aftermarket supplier of fluid connectors across commercial, industrial, and aerospace sectors. This adapter's straightforward design prioritizes reliability over novelty—a characteristic that defines professional-grade hydraulic components used in mission-critical systems where failure is not an option.
