A Backup Ring is used to prevent extrusion or deformation of the primary seal that is fitted around the respective groove of the cylinder head. By providing support to the primary seal, the backup ring helps maintain the integrity of the seal prevents it from being forced into the extrusion gap, and minimizes the risk of leakage.Attributes:• Helps to reduce the friction between the mating parts• Ensures the proper sealing function after being compressed with the primary sealing elementApplications:A Backup Ring acts as a mechanical barrier in preventing the entry of external elements inside the hydraulic cylinder head and works in conjunction with the primary seal to maintain a reliable and leak-free sealing and ensure its sealing capabilities.
