A cushioning seal, or dot wiper, is crucial for hydraulic and pneumatic systems, protecting internal components from contamination and cushioning the piston's impact. This seal removes dirt, debris, and moisture from the rod, preventing damage to the system. Its unique dot pattern enhances particle removal efficiency. Made from durable materials like polyurethane or rubber, it withstands high pressures and temperatures, ensuring machinery cleanliness and longevity. Essential in applications needing precise control, such as in automotive and heavy machinery, the cushioning seal's dual role as a wiper and shock absorber is vital for maintaining system efficiency and reliability.
