CT19370C99: A worn back-up ring can allow seal extrusion under pressure, leading to fluid loss and reduced system performance. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT19370C99. The back-up ring functions as a rigid support element placed behind a seal to prevent deformation. During operation, the ring maintains seal position within its groove under high-pressure cycles. A failed back-up ring may cause sudden seal collapse and external leakage. Keeping this component in sound condition helps preserve seal integrity in static applications. Verify the serial number or application, then call (562) 693-7748.

Part number variants: CT19370C99, ct19370c99
