SEAL KIT - HYDRAULIC CYLINDER (JCB JC991/20007)

JC991/20007: 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 component's ability to contain pressure and keep contaminants out. The JCB catalog reference for this aftermarket replacement part is JC991/20007. This seal kit is a collection of elastomeric rings and wipers that seal the gap between moving and stationary cylinder parts. A common failure consequence is external fluid drips that create slippery surfaces and require frequent topping off. Keeping a seal kit in sound condition helps maintain consistent actuation speed and prevent internal bypass. Verify the serial number or application, then call (562) 693-7748.
