SCREW - BLEEDER (Mitsubishi MB1921-64081)

MB1921-64081: 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 MB1921-64081. The screw functions as a threaded fastener that provides a controlled release point for trapped air or excess fluid. During normal operation, a bleeder screw must maintain a tight seal to prevent leaks. If the screw becomes stripped or corroded, it may fail to hold pressure, causing system inefficiency or failure. Keeping a bleeder screw in sound condition helps ensure consistent system performance. Verify the serial number or application, then call (562) 693-7748.
