GASKET - COPPER RING (Mitsubishi MB1200A00312)

A damaged copper ring gasket can allow fluid or gas to escape from a sealed joint. During assembly, this gasket compresses to fill surface irregularities between mating components. The copper material provides a durable sealing surface that resists deformation under repeated thermal cycles. Keeping this gasket in sound condition helps maintain consistent clamping force at the connection point. This aftermarket replacement part references Mitsubishi part number MB1200A00312. Verify the serial number or application, then call (562) 693-7748. The gasket's function is to prevent leakage at a static interface.
