#10 Flare 3/8in Pipe Str Black

The #10 Flare 3/8in Pipe Str Black is a precision adapter fitting engineered for professional-grade hydraulic and fluid transfer applications in automotive systems. Built by AEROQUIP—a trusted name in motorsports and heavy-duty vehicle modifications—this flare connector serves as a critical junction point in brake lines, fuel systems, and transmission cooler circuits where reliability and leak-free performance are non-negotiable. Whether you're fabricating a custom fuel system, upgrading brake lines on a high-performance build, or maintaining OEM-spec hydraulic integrity, this adapter delivers the durability expected in competition and street applications.

This straight flare connector features a #10 SAE flare design—a 37-degree JIC standard that ensures consistent sealing across military and automotive hydraulic standards. The 3/8-inch pipe thread specification accommodates mid-size fluid lines common in V8 conversions, LS swaps, and factory restoration projects, while the black anodized or plated finish resists corrosion in engine bays and underbody environments. The compact 2.3 x 1.15 x 3.75-inch form factor and featherweight 0.07-pound design minimize integration complexity, allowing mechanics to route lines efficiently without bulk or stress concentration at connection points.

Ideal for fabricators, restoration shops, and serious DIY enthusiasts, the #10 Flare 3/8in Pipe Str Black adapts seamlessly to custom brake and fuel system builds where OEM connectors don't fit modern configurations. Installation requires standard flare wrench technique—no special tooling—and compatibility spans vintage hot rods, modern turbo platforms, and motorsport-grade hydraulic systems. This AEROQUIP adapter (MPN FCM5185) pairs reliably with matching flare fittings and works across temperature ranges typical of street and track environments, making it an essential component for anyone upgrading or fabricating fluid systems where precision and zero-tolerance for leaks are mandatory.
