The Backup Seal Ring is alongside a primary seal to control seal movement during pressure changes. It helps limit seal extrusion into clearances that can occur during system operation. Supporting the primary seal helps maintain an effective sealing line under load. The ring improves sealing stability during pressure cycles and directional changes. It helps reduce leakage and loss of pressure during operation. Reliable sealing control helps ensure consistent equipment performance and dependable system function.Attributes:• Maintains effective sealing under varying pressure levels.• Improves sealing reliability during pressure changes.• Supports stable sealing during directional motion.Applications: The Backup Seal Ring is located inside the stud tensioner cylinder, where it supports the primary seal by controlling seal movement and maintaining stable hydraulic pressure during stud tensioning operations.
