Piston seals are used in hydraulic and pneumatic cylinders to prevent fluid from bypassing the piston, ensuring efficient pressure transfer and smooth motion. Designed for dynamic sealing, they provide high pressure resistance, low friction, and long service life in demanding applications.

Clark Seals provides full engineering support to optimize seal performance and extend equipment life. Our team collaborates with engineers to refine design elements, material selection, and key performance factors like lubricant compatibility, surface finish, and tolerances. Whether for new machinery or existing equipment, we deliver precision-engineered sealing solutions that minimize wear, reduce failure rates, and ensure long-term efficiency in even the most demanding applications.

Wiper seals, also known as scrapers, are used in hydraulic and pneumatic cylinders to prevent dirt, dust, and moisture from entering the system as the rod retracts. Installed at the cylinder opening, they protect internal components from contamination, reducing wear and extending system life.

Buffer seals are installed in hydraulic cylinders ahead of the primary rod seal to absorb pressure spikes and reduce stress on the sealing system. They help manage residual pressure and fluid bypass from the piston, enhancing the performance and lifespan of downstream seals.

Wear rings guide the piston and rod within hydraulic cylinders, preventing metal-to-metal contact and maintaining proper alignment. Made from low-friction, high-strength materials, they absorb side loads and ensure smooth operation in high-speed or heavy-duty applications.
