The Backup Ring is a component included in seal kits, used to provide structural support to primary sealing elements such as O-rings. It prevents extrusion or deformation of seals when exposed to high-pressure conditions, thereby enhancing seal durability and performance. By maintaining the shape and position of the sealing element, the backup ring ensures consistent sealing efficiency and prevents fluid leakage.Attributes:• Prevents extrusion of primary sealing elements.• Provides structural support under high pressure.• Maintains sealing integrity and performance.Applications: The Backup Ring is used in hydraulic and pneumatic seal kits to support sealing elements, prevent extrusion, and maintain reliable sealing under high-pressure operating conditions.
