ELBOW AN823-4 (P/N an823-4) - New Surplus

The AN823-4 is a 45-degree flared tube elbow connecting 1/4-inch 37° flared tubing to 1/8 NPT ports in aircraft fluid systems. This brass fitting adapts between flare and pipe thread standards, enabling directional changes in fuel, hydraulic, and oil lines. Installation requires mating the flared tube end with the elbow's flare seat and threading the NPT port into the system component.

Torque and thread-sealing compound follow aircraft maintenance manual specifications. The 45-degree angle allows compact routing in confined engine bay and fuselage spaces.
