The Stick Cylinder Backup Ring is used to be installed behind the primary piston seal, acting as a backup to prevent the seal from being forced out of its groove under extreme operating pressures and loads. It provides an additional barrier against fluid or gas leakage. When the primary piston seal is subjected to high pressure, the backup ring helps to distribute the load and prevent the seal from being extruded or damaged, ensuring the integrity of the hydraulic unit.Attributes:• Prevents premature failure and ensures the component continues to provide reliable performance.• Ensure consistent performance across a wide range of operating temperaturesApplications:The Stick Cylinder Backup Ring helps to maintain the effectiveness of the primary piston seal, reducing the risk of leaks. It protects the primary seal from wear, abrasion, and extrusion.
