GASKET FLANGE (Komatsu KO6733-21-5521)

KO6733-21-5521: A damaged flange gasket can allow fluid or gas to escape at a bolted joint, leading to pressure loss or contamination. During disassembly, a worn gasket often shows compression set or cracking that compromises the seal. Keeping a flange gasket in sound condition helps maintain system integrity and prevent leaks. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO6733-21-5521. The gasket type provides a static seal between two flat surfaces, relying on compression to block leakage. A common failure consequence is external leakage that can cause gradual system inefficiency or require unscheduled downtime. Verify the serial number or application, then call (562) 693-7748.
