SEAL KIT - HYDRAULIC CYLINDER (Komatsu KO684827)

A damaged seal kit can cause hydraulic cylinder leakage and reduced system pressure. During inspection, a seal kit may show wear from normal cycling and exposure to hydraulic fluid. The seal kit contains multiple sealing elements that prevent fluid bypass between moving cylinder components. A worn seal kit allows internal leakage, which can lead to sluggish cylinder movement and loss of holding force. Keeping a seal kit in sound condition helps maintain consistent cylinder performance and prevents contamination ingress.
