Chesterton 8K a stacked v-ring set with a positive-rake design to provide optimum operating performance. Unlike conventional stacked sets, this design makes contact through the center to ensure even loading, longer sealing life, and minimal gland pressure.Chesterton 27K a single-acting, stacked v-ring set with a positive rake design to provide optimum operating performance.

Chesterton 11K Split Seal is a patented design made up of two components intended for use in hydraulic cylinder and press applications. This product was designed to promote machine productivity and lower operating costs. The split configuration simplifies installation.

A single-acting rod seal with a positive-rake u-cup design-lip that wipes contaminants away from the mating surface while in operation. Since it conforms to surface irregularities to effectively control leakage, this rugged, rubber-based construction is ideal for older worn, hydraulic equipment.

A design that incorporates a unique dynamic-lip geometry which provides the optimal sealing force required for low-pressure pneumatic applications. The Chesteron 23K design is manufactured using a machining process which allows the flexibility to create any size based on equipment dimensions. The radiused-lip design ensures a continuous lubricating film is maintained, which minimizes operating temperature and wear—delivering excellent sealing performance. 

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.

Chesterton 22K Rod & Piston Seal is a single-acting u-cup design with a special seal-lip geometry that provides zero leakage throughout the entire operating range. The sturdy static lip stabilizes the seal to prevent rolling while the negative-rake design eases installation. This seal design is offered as a rod or piston seal and provides excellent performance in hydraulic applications.
