Chesterton 22K Rod and Piston Seal is a single-acting U-Cup design with seal lip geometry that provides zero leakage throughout the entire operating range. The sturdy, static lip stabilizes the seal to minimize rolling, while dynamic lip design minimizes issues associated with low-pressure sealing, provides additional stability, and easy installation. This seal design is offered as a rod or piston seal and provides excellent performance in hydraulic applications.

A number of additional designs have been derived from the original 22K design to address specific needs and applications in the market. These include highly customizable sizes based on equipment dimensions and the use of anti-extrusion rings for use in equipment with excessive clearances.
