Piston Seal Assemblies

Universal Rod/Piston U-Cups - Symmetrical

Piston seals prevent pressurized fluid from leaking across the cylinder head as the pressure pushes the piston down the cylinder bore. A single-acting piston seal provides the optimal sealing solution for unidirectional hydraulic systems. A double-acting piston seal is capable of sealing the pressurized fluid from both sides in a bidirectional hydraulic system.
