145-5798: 262mm Inner Diameter Backup Ring

A Backup Ring provides support to the O-ring under high pressure and dynamic conditions, where there is a risk of extrusion. By offering additional stability and resistance to deformation, the backup ring ensures a reliable and leak-free seal, thereby preventing fluid and gas from escaping the system. Its design features an accurate fit with the O-ring, acting as a mechanical barrier against extrusion, abrasion, and wear, thus extending the service life of the sealing unit.

Attributes:
• Provides support to prevent seal extrusion and deformation under high-pressure applications.
• Facilitates proper sealing by maintaining seal shape and integrity.
• Provides a reliable barrier against fluid leakage.
• Enhances sealing efficiency by maintaining consistent pressure.

Applications:
A Backup Ring is used in the hydraulic brake valve in equipment and prevents extrusion and maintains seal integrity under high pressure, ensuring reliable brake operation in equipment.
