A Hydraulic Cylinder Ring, also known as a piston ring or sealing ring, is a component designed to provide a sealing function within a hydraulic cylinder. It is typically installed on the piston and creates a dynamic or static seal between the piston and the cylinder bore.

Attributes:
Provide the necessary sealing and wear resistance.
Ensure a tight fit against the cylinder wall and prevent leakage.

Applications:
A Hydraulic cylinder ring acts as a protective barrier, preventing direct metal-to-metal contact and reducing frictional losses, and enhancing its efficiency. This is widely used in Cat® 302C, 303, 303.5C, 303.5D, 303.5E, 303C, 303E, 304, 304C, 304D, 304E, 305.5D, 305E, 307E, MM20T, MM25T, MM30CR, MM30T, MM35T and MM40CR Excavators, D3K and D5K Track Type Tractor.
