SCREW - BLEEDER (Mitsubishi MB0911143)

A damaged bleeder screw can allow air or fluid to escape from a sealed system, leading to pressure loss or contamination. This aftermarket replacement part references Mitsubishi as the OE maker and carries the cross-reference part number MB0911143. The screw's plain mechanical function is to provide a threaded seal that can be opened for purging trapped air. A common failure consequence is that a stripped or corroded bleeder screw may not seal properly, causing gradual leakage. Keeping a bleeder screw in sound condition helps maintain consistent system pressure during routine service intervals. During inspection, a bleeder screw should be checked for thread damage or corrosion that could compromise its seal. Verify the serial number or application, then call (562) 693-7748.
