RING-SEALING (Doosan DWA138684)

A damaged sealing ring can allow fluid or gas to escape, reducing system pressure and leading to component inefficiency. Doosan originally cataloged this part as DWA138684, and the aftermarket replacement is offered as a cross-reference. The ring-sealing type creates a static barrier between two mating surfaces to prevent leakage. Over time, a worn seal may cause gradual loss of containment, resulting in visible drips or audible hissing. In a typical service context, a failed sealing ring often forces unscheduled downtime for replacement. Verify the serial number or application, then call (562) 693-7748.
