SEAL KIT - HYDRAULIC CYLINDER (JCB JC991-00030)

JC991-00030: A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. During inspection, a seal kit may show visible wear, hardening, or cracking that compromises its sealing ability. Seal kit condition directly affects the cylinder's ability to maintain pressure and prevent external leakage. Keeping a seal kit in sound condition helps avoid fluid loss and contamination of the hydraulic system. This aftermarket replacement part references the JCB catalog number JC991-00030. The kit includes multiple seals and o-rings designed to restore the cylinder's sealing integrity. Verify the serial number or application, then call (562) 693-7748.
