RING - BACK UP (CAT CT19370-C63)

A worn back-up ring can allow seal extrusion under high pressure, leading to fluid leaks and reduced system efficiency. This aftermarket replacement part is cataloged under CAT reference CT19370-C63. The ring functions as a mechanical barrier that supports the primary seal in a groove. Without a sound back-up ring, the seal may deform and fail prematurely. In a typical static or dynamic sealing application, the ring prevents the seal from being forced into the clearance gap. Verify the serial number or application, then call (562) 693-7748. Call (562) 693-7748 after checking the serial number or application.
