SEAL KIT - HYDRAULIC CYLINDER (Doosan DW7135489)

A damaged seal kit can allow hydraulic fluid to leak past the piston, reducing cylinder force and causing sluggish or incomplete movement. During a cylinder rebuild, replacing the seals restores the ability to hold pressure and maintain consistent actuation. The Doosan catalog reference for this aftermarket replacement part is DW7135489. This seal kit contains the elastomeric rings and wiper seals that prevent external leakage and internal bypass. A worn seal often leads to visible drips or a gradual loss of positioning accuracy. The item ships at approximately 0.445 pounds. Verify the serial number or application, then call (562) 693-7748.
