A worn back-up ring can allow extrusion of the primary seal under pressure. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB0666077. The back-up ring is a retaining ring type that provides mechanical support to a seal in a groove. Its general function is to prevent seal deformation when the system experiences high pressure. A common failure consequence is seal extrusion, which leads to fluid leakage and reduced system efficiency. During routine service, a back-up ring may show signs of compression set or cracking. Verify the serial number or application, then call (562) 693-7748.
