#3 Flare 1/8in Pipe Male Black

The AEROQUIP #3 Flare 1/8in Pipe Male Black adapter fitting is a precision hydraulic and pneumatic connection component designed for fuel systems, brake lines, and transmission cooler circuits in high-performance and stock vehicle builds. This male flare adapter serves as a critical juncture point where rigid or flexible hose lines meet manifold blocks, control valves, or distribution blocks in both carbureted and fuel-injected engines.

AEROQUIP's #3 flare designation corresponds to a 37-degree JIC (Joint Industry Council) flare geometry, the industry standard for automotive hydraulic fittings that demand both reliability and compact envelope in engine bays and frame rails. The 1/8 NPT Male thread connection creates a sealed interface when paired with matching female flare ports, relying on cone-to-cone metal-to-metal contact rather than O-ring compression for its seal integrity. The black zinc-plated finish resists corrosion in salt environments and provides visual clarity for system identification during assembly and troubleshooting.

Whether you're restoring a classic muscle car, upgrading a modern turbo platform, or fabricating a custom fuel delivery system, a properly rated flare fitting ensures leak-free performance under pressure cycling and thermal expansion. This fitting is lightweight enough for weight-conscious builds while maintaining the material density required to withstand fuel system pressures typically ranging from 40–80 psi in carbureted applications.
