Piston cup seals play a vital role in the performance of hydraulic and pneumatic cylinders. Designed to fit over the piston head, these seals form a secure barrier that prevents fluid or air from bypassing during operation, ensuring efficient system performance and pressure retention.
Crafted from high-performance materials such as Nitrile (NBR), Viton, polyurethane, and other durable elastomers, these seals are engineered to withstand pressure, temperature extremes, and wear. The combination of premium materials and precision manufacturing ensures consistent sealing even under heavy loads and repetitive motion.

Engineered for Demanding Conditions

From high-pressure hydraulic systems to fast-cycling pneumatic applications, piston cup seals are built to preserve system integrity. Their cup-shaped design offers excellent sealing efficiency while reducing friction, promoting smoother movement, and extending equipment life. In environments where contamination is a concern, these seals also act as a barrier to debris, safeguarding sensitive components from premature failure.

Versatile Applications Across ...
... Industries

These seals are trusted in a wide range of equipment, including industrial presses, automated machinery, agricultural equipment, and marine systems. They are particularly effective in double-acting cylinders and long-stroke, high-speed applications where consistent performance is crucial for uptime and operational safety.

Custom Sealing Solutions

Standard seals may not always align with the specific dimensions or material requirements of every system. That’s why custom piston cup seals are available to meet exact tolerances and application needs. By providing dimensions or technical drawings, a seal can be engineered to ensure optimal fit and function for any system.
