SEAL KIT - HYDRAULIC CYLINDER (JCB JC991/10120)

JC991/10120: A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. The JCB catalog reference for this aftermarket replacement part is JC991/10120. This seal kit contains the elastomeric seals and wiper rings that contain pressurized fluid within a hydraulic cylinder. A leaking seal kit often leads to visible fluid puddles beneath the cylinder and increased operating temperatures. During a cylinder rebuild, replacing the seal kit restores the component's ability to hold pressure. Verify the serial number or application, then call (562) 693-7748.
