SEAL - U - CUP (Doosan DWD511210)

DWD511210: A damaged U-cup seal can allow fluid leakage past the sealing surface, reducing system pressure and causing erratic operation. During inspection, a worn seal may show visible cracking or flattening of the lip. Seal condition directly affects the ability to contain fluid under pressure in a reciprocating rod or piston application. Keeping a U-cup seal in sound condition helps prevent contamination ingress and fluid loss. This aftermarket replacement part references the Doosan catalog number DWD511210. The seal is a U-cup type, which relies on a flexible lip to create a dynamic seal against a moving shaft. Verify the serial number or application, then call (562) 693-7748.
