A Backup Ring for a boom cylinder is a resilient annular component made from durable materials, that is designed to be installed around the piston or rod of a hydraulic cylinder. Its purpose is to provide an additional seal, protect primary seals from wear, withstand high hydraulic pressures, and exclude contaminants from the hydraulic system.

Attributes:
• Capable of withstanding high hydraulic pressures and temperature variations.
• Resistance to hydraulic fluids and chemicals.
• Ensures hydraulic system integrity and continuity.

Applications:
The Backup Ring for a boom cylinder improves hydraulic system reliability by preventing fluid leaks, enhancing pressure resistance, excluding contaminants, and extending the lifespan of heavy machinery's hydraulic components.
