#4 Flare End Blkhd Union

The AEROQUIP #4 Flare End Bulkhead Union (FCM2071) is a specialized hydraulic fitting designed for applications that require a secure, leak-free connection across panel or bulkhead walls. This AN-sized coupling connects two 4 AN male ports in a direct line, making it essential for pressurized fluid systems in industrial and automotive environments.

Constructed from lightweight aluminum and finished with a blue anodized coating, this bulkhead union offers excellent corrosion resistance, making it suitable for environments exposed to moisture and temperature fluctuations. The flare-end design ensures a reliable seal compatible with AN flare-type hydraulic hose and tubing systems.

Ideal for technicians working on custom hydraulic circuits, this fitting simplifies wall-mounted configurations by eliminating the need for external elbows or adapters. It is particularly beneficial in applications such as fuel lines in race vehicles and fluid distribution networks where weight and space efficiency are critical.
