Rod seals are hydraulic sealing components installed in the cylinder head to prevent hydraulic fluid from leaking outside the cylinder along the reciprocating rod. They are critical for maintaining system pressure, ensuring smooth operation, and protecting hydraulic systems from contamination.

Designed to perform under high pressure and dynamic conditions, rod seals are manufactured using durable materials such as Polyurethane (PU), PTFE, NBR, and FKM, offering excellent wear resistance and long service life.
