BACK -UP RING (Hyster HY19993)

A damaged back-up ring can allow seal extrusion under pressure, leading to fluid leaks and reduced system efficiency. During inspection, a worn back-up ring may show cracking or deformation that compromises its support function. The condition of a back-up ring directly affects the seal's ability to withstand high-pressure loads. Keeping a back-up ring in sound condition helps prevent premature seal failure and costly downtime.
