SEAL KIT - HYDRAULIC (Hyster HY0664839)

HY0664839: A damaged seal kit can allow hydraulic fluid to leak past piston or rod seals, reducing system pressure and causing sluggish or incomplete movement. During inspection, a worn seal kit may show visible cracking, hardening, or flattened cross-sections that indicate loss of sealing ability. Seal kit condition directly affects the ability to maintain consistent fluid containment within a cylinder assembly. Keeping a seal kit in sound condition helps prevent external fluid drips that create slip hazards and require frequent refilling. This aftermarket replacement part references Hyster catalog number HY0664839. The kit ships at approximately 0.044 pounds. Verify the serial number or application, then call (562) 693-7748.
