SEAL - O-RING (Doosan DWD513090)

A damaged seal can allow fluid leaks that compromise system pressure and lead to component wear. The Doosan catalog reference for this aftermarket replacement part is DWD513090. This O-ring seal provides a static or dynamic barrier between mating surfaces to prevent fluid or gas escape. Its plain mechanical function is to compress into a groove and create a tight seal under assembly torque. A common failure consequence is gradual leakage that reduces operating efficiency and may cause intermittent performance issues. In a typical usage context, this seal is replaced during routine overhauls when disassembly reveals hardened or cracked rubber. Verify the serial number or application, then call (562) 693-7748.
