Chesterton 22KE Rod & Piston Seal

 

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​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.
