The Stick Cylinder Piston Dust Ring creates a protective sealing barrier around the piston of the stick cylinder. Its role is to prevent dust, dirt, moisture, and other harmful particles from entering the hydraulic system, which otherwise causes wear or damage to components. By keeping contaminants out, the dust ring helps extend the service life of the piston, seals, and internal cylinder surfaces.Attributes:• Provides a protective seal around the piston surface.• Prevents dust, dirt, and moisture from entering the cylinder.• Protects internal seals from premature wear.Applications: The Stick Cylinder Piston Dust Ring is installed on the piston of the stick cylinder, where it prevents entry of external contaminants and protects internal sealing components for reliable hydraulic performance.
