SEAL (Mitsubishi MB1149744)

A damaged seal can allow fluid leakage, leading to pressure loss and component wear. The Mitsubishi catalog reference for this part is MB1149744. This aftermarket replacement seal is a static or dynamic barrier that prevents contaminants from entering a closed assembly. Its plain mechanical function is to block the passage of oil, grease, or air between two mating surfaces. A common failure consequence is gradual seepage that reduces system efficiency and may cause premature bearing failure. In a typical usage context, this seal is installed during routine overhaul of rotating shafts or stationary housings. Verify the serial number or application, then call (562) 693-7748.
