Chesterton 22KE Rod & Piston Seal
Eliminates Low-Pressure Leakage


​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​A single-acting, continuous u-cup design that incorporates the use of an O-ring to increase pre-load capabilities for low pressure. The O-ring energizes the seal—increasing its pre-load capabilities in the absence of system pressure.

This seal design is offered as a rod or piston seal and provides excellent performance in hydraulic applications.

Single-acting, u-cup design provides zero leakage throughout the entire operating range​
O-Ring loader energizes seal and compensates for compression setting
Lip geometry stabilizes seal to prevent rolling and eases installation
Machining process allows the​ flexibility to create any size
