Aeroquip FCM2791 90-Degree Elbow Bulkhead Union -04AN Steel with Locknut

The Aeroquip FCM2791 is a 90-degree elbow bulkhead union fitting conforming to the AN 833 standard. Built from steel with a durable finish, this fitting connects -04AN (dash 4) male AN ports on both ends, making it ideal for routing performance fuel, oil, or fluid lines cleanly through firewalls, panels, and bulkheads at a precise 90-degree angle.

Key Features:

• 90-degree elbow bulkhead union — routes lines through panels with a clean right-angle exit
• -04AN x -04AN — identical dash 4 AN connections on both ends for straightforward in-line installation
• Steel construction — provides strength and durability for high-demand performance and racing applications
• Includes locknut — everything needed for a complete, secure bulkhead installation is in the box
• AN 833 standard — conforms to military/aerospace AN fitting specifications
• SAE 37° flare seat — ensures a leak-free, pressure-rated connection compatible with standard AN hose ends
• Part of Aeroquip's comprehensive performance plumbing lineup, trusted by racers and builders for decades
