SEAL - DUST (Mitsubishi MB0000111300)

A damaged dust seal can allow contaminants to enter a component, leading to accelerated wear and premature failure. The aftermarket replacement part cross-references Mitsubishi part number MB0000111300. This seal type serves as a barrier against dirt, debris, and moisture in rotating or sliding assemblies. Its primary mechanical function is to exclude foreign particles from the sealed area. When a dust seal fails, the resulting contamination can cause scoring, binding, or leakage in the protected mechanism. Keeping a dust seal in sound condition helps maintain the integrity of the surrounding assembly. Verify the serial number or application, then call (562) 693-7748.
