Dual Sealing System is available on long-stroke hydraulic cylinders to prevent rod-seal leakage in extreme environments. It is more resilient than standard sealing systems, ensuring it remains in constant contact with the rod even during large amounts of pressure spiking, resulting in rod deflection and lateral movement. Wear rings provide added protection. Standard Cylinders (in double and single-acting designs) and
Piggy-back Cylinders can use the sealing system.
