Rod Seals

The function of a rod seal is to prevent fluid bypass along the dynamic (rod or ram) and static (stuffing box bore) surfaces while a cylinder is operating under various operating conditions. Chesterton offers numerous, highly-effective rod seal profiles to choose from, including u-cup, stacked and compression designs, depending upon the application requirements and operating conditions.

Wiper Seals

The function of a wiper is to effectively clean and dislodge foreign matter from a reciprocating rod/ram during the retraction stroke to prevent contaminants from entering the system. A positive-rake profile made from a durable sealing material has proven to dislodge foreign matter effectively from a rod/ram blocking system contamination and minimize additional scoring in both hydraulic and pneumatic applications.

Piston Seals

The function of a piston seal is to prevent fluid bypass between the piston head (static) and cylinder bore (dynamic) while a hydraulic or pneumatic cylinder is operating under various operating conditions. Chesterton offers numerous, highly effective piston seal profiles to choose from, including u-cup, stacked and compression designs, depending upon the application requirements and operating conditions.

Compression Seals

Compression seals are typically designed with a higher initial pre-load than other designs which helps to improve sealing at lower pressures. These profiles are typically designed for use in single cavity groove hydraulic or pneumatic applications as a rod, piston, or static seals. They are able to seal pressure in both directions, and come in various types, such as cap seals, piston cups and various static seals and stacked v-rings.

Static Seals

The function of a static seal is to prevent fluid bypass between mating surfaces in which there is little or no relative motion when exposed to zero, low, or high pressures. There are various profiles used in industry, from O-rings to custom profiles, which can be used based upon equipment and operating conditions. Chesterton experts can help you choose the right material and profile to maximize performance.
