O-RING (Doosan DW25K40204)

A damaged O-ring can lead to fluid leaks that compromise system pressure. During inspection, an O-ring may appear hardened or cracked, indicating it is no longer sealing effectively. O-ring condition directly affects the containment of fluids within a closed system. Keeping an O-ring in sound condition helps prevent contamination from entering the system. This aftermarket replacement part references the OE maker Doosan and cross-references part number DW25K40204. The O-ring functions as a static seal between mating surfaces, relying on compression to block fluid passage. Verify the serial number or application, then call (562) 693-7748.
