A Backup Ring is a seal designed to prevent fluid leakage between mating surfaces. It serves as a backup to primary seals, providing additional protection against pressure differentials and extrusion, ensuring a reliable seal even in challenging operating conditions.

Attributes:
• Resistant to wear and degradation.
• Resistant to pressure differentials.
• Durable material for long-lasting use.

Applications:
A Backup Ring is positioned alongside primary seals, this backup ring seal is installed in hydraulic cylinders, valves, pumps, and other components where there is a need to maintain a secure fluid-tight seal.
