The Aeroquip #10 Flare Union Black (FCM5054) is a -10 AN to -10 AN male flare union built to join two -10 AN flare ports in a straight, inline connection. It's aimed at builders running hydraulic, fuel, and oil lines in automotive, motorsports, aerospace, and industrial setups. Machined from black anodized aluminum, this union keeps weight down where steel would add bulk, which matters on race plumbing and dry-sump systems. It mates to standard 37-degree male flare hose ends and adapters, so it drops into existing AN line work without specialty tooling. Find it alongside the rest of our fittings, hoses, and valves.
This union follows the AN 815 flare union specification and seals on the 37-degree flare angle used across automotive and aerospace fluid systems. Both ends are -10 AN male, so the fitting bridges two female -10 AN hose ends or swivels in a straight run. The black anodized aluminum body resists corrosion and gives a finished look on visible plumbing. Per the Aeroquip Performance Products catalog, the line is quality certified to recognized manufacturing standards and built in the United States. Because it carries no gasket or O-ring, the metal-to-metal flare seal handles the pressure and temperature swings common in fuel and oil circuits. Pair it with matching 10 straight hose ends for a complete -10 line.
Reach for this union when you need to splice two -10 AN lines, extend a run, or join two hose assemblies without adding a bend. It works in fuel delivery, oil feed and return, power steering, and coolant plumbing where a clean 37-degree flare seal is required. Builders running large-bore -10 lines for high-flow pumps will find it a straightforward way to link sections. Browse our other 10 flare unions and AN adapters to round out a system, or grab a few 10 AN plugs to cap unused ports.
It joins two -10 AN male flare ports in a straight, inline configuration. Each end is a -10 AN male flare, so the union bridges two female -10 AN hose ends or swivels, letting you splice or extend a line without adding a bend.
It seals on the 37-degree flare angle (AN 815 union specification) used across automotive, motorsports, and aerospace fluid systems. The metal-to-metal flare seal needs no gasket or O-ring, which suits the pressure and temperature swings found in fuel and oil circuits.
The union is machined from aluminum with a black anodized finish. Aluminum keeps weight down compared to steel fittings, and the anodized coating resists corrosion while giving a clean look on visible plumbing. It's manufactured in the United States.
Yes. Because both ends are -10 AN male flare conforming to the 37-degree standard, the union mates with any standard female -10 AN hose end, swivel, or adapter. No specialty tooling is required to install it into existing AN line work.
