Replacing worn sealing components with the correct seal kit can help restore cylinder sealing performance, maintain hydraulic pressure and support reliable bucket cylinder operation in demanding working environments.
This seal kit is suited to heavy-duty applications including construction, earthmoving, quarrying, mining, excavation and material handling. Proper hydraulic cylinder inspection and correct seal installation are recommended to help prevent premature wear and maintain dependable excavator performance.
