1/8in female Pipe To #3 Flare

The 1/8in female pipe to #3 flare adapter is a precision hydraulic and pneumatic fitting designed to connect NPT (National Pipe Thread) female ports to AN (Army-Navy) male flare connections. This straight adapter serves industrial, automotive, and fluid power applications where reliable, leak-free transitions between different thread standards are essential. Whether you're assembling hydraulic systems, maintaining aircraft components, or building custom fluid lines, this adapter bridges incompatible connection types with proven performance.

Manufactured by AEROQUIP, a trusted leader in fluid conveyance solutions, this fitting is engineered from durable steel and finished with zinc oxide plating for corrosion resistance in demanding environments. The straight configuration eliminates elbows or additional bends, reducing turbulence and pressure drop while simplifying installation in tight spaces. The 1/8 inch NPT female threads mate directly with standard NPT ports, while the #3 AN male flare end accommodates matching flare hose assemblies with a secure, bubble-sealed connection that resists vibration-induced loosening.

Technicians and engineers rely on this adapter for retrofit applications, system repairs, and custom fluid-line fabrication where mixing thread standards cannot be avoided. Its compact footprint—weighing just 0.07 lbs—suits space-constrained installations without sacrificing durability. Installation is straightforward: apply appropriate thread sealant to the NPT female end and hand-tighten before final wrench engagement on the #3 flare nut. Compatible with hydraulic oils, air, water, and other industrial fluids within safe pressure and temperature limits, this AEROQUIP fitting delivers reliability across marine, agricultural, construction, and automotive sectors.
