SEAL KIT - HYDRAULIC CYLINDER (JCB JC991/00103)

JC991/00103: A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing erratic movement. During inspection, a worn seal kit may show visible cracking or hardening of the rubber elements. Seal kit condition directly affects the ability of a hydraulic cylinder to maintain pressure and hold a load steady. Keeping a seal kit in sound condition helps prevent external leaks that can create slippery surfaces and environmental hazards. This aftermarket replacement part references the JCB catalog number JC991/00103. The kit includes multiple seals and wipers designed to contain fluid and exclude contaminants from the cylinder bore. Verify the serial number or application, then call (562) 693-7748.
