The GRACO 555790 is a rupture disk designed for high-pressure applications within GRACO equipment. It is constructed to act as a safety device, bursting at a specified pressure to protect system components. The material is not explicitly stated, but rupture disks are typically made from metals or composites for durability and reliability.

Key Features:

• Rupture Disk
• .688" (11/16")
• 7500 PSI
• Designed for use with GRACO equipment requiring a .688" rupture disk at 7500 PSI
• Acts as a safety device to protect equipment from overpressure
• Reliable performance at high pressures
• Easy to replace as part of routine maintenance

Applications:
Used in high-pressure fluid handling systems, such as those found in lubrication, paint, and industrial fluid transfer applications, where overpressure protection is critical.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and safety in high-pressure systems.
• Always follow manufacturer guidelines for installation and replacement
• Inspect the rupture disk and surrounding components for wear or damage before installation
• Ensure the system is depressurized before replacing the disk
• Use appropriate tools and safety equipment when working with high-pressure systems
