SEAL KIT - HYDRAULIC CYLINDER (JLG JLJCB-991-00103)

JLJCB-991-00103: A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. During inspection, a worn seal kit may show visible cracking, hardening, or flattened cross-sections that indicate imminent failure. Seal kit condition directly affects the cylinder's ability to maintain pressure and hold a load steady. Keeping a seal kit in sound condition helps prevent external leaks that create slippery surfaces and potential safety hazards. This aftermarket replacement part references JLG catalog number JLJCB-991-00103. The item ships at approximately 0.14 pounds. Verify the serial number or application, then call (562) 693-7748.
