#3 Flare 90 Deg Elbow Union Black

The AEROQUIP #3 Flare 90 Degree Elbow Union Black (FCM5186) is a precision hydraulic and fuel line adapter designed for automotive applications that require directional flow changes. This fitting is ideal for mechanics and fabricators who need reliable, leak-free connections in various systems, particularly in custom cooling loops and brake line routing.

Built to AEROQUIP standards, the #3 flare union features a 90-degree elbow geometry that redirects fluid flow efficiently, minimizing the need for bulky offset adapters. The black finish provides corrosion resistance, making it suitable for underhood environments. The flare-thread design is compatible with -3 AN fittings, which correspond to a specific inner diameter, ensuring a consistent seal across repeated assembly cycles.

Restorers, performance builders, and race fabricators will find this fitting particularly beneficial when constructing custom fuel delivery systems or modified brake circuits. Installation is straightforward for anyone familiar with flare-thread connections—simply hand-tighten and then snug with a wrench to avoid over-torquing and damaging the flare seat.
