GASKET (P/N 77813) - As Removed

Part 77813 is a folded-steel gasket designed to seal mating surfaces in aircraft fuel system connections. This gasket prevents leaks between flanged components by creating a reliable seal when properly installed on clean surfaces. Following SAE AS678 specifications for folded-steel construction, it's used in fuel system assemblies across general aviation and commercial aircraft.

Installation requires clean mating surfaces and application of specified torque per the aircraft maintenance manual. The gasket maintains system integrity under pressure and temperature cycling typical of aviation fuel systems.
