FITTING - GREASE (Mitsubishi MB3)

A damaged grease fitting can allow contaminants into the lubrication point, leading to accelerated wear of moving components. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB3. The fitting serves as a conduit for introducing grease under pressure into a bearing or joint. Its plain mechanical function is to seal against the grease gun nozzle during lubrication. A concrete generic failure consequence is that a clogged or broken fitting prevents proper grease delivery, causing dry operation and eventual component seizure. The item ships at approximately 0.022 POUNDS. Verify the serial number or application, then call (562) 693-7748.
