The GRACO 564355 is a rupture indicator designed for use in Trabon series progressive divider valve applications. It is a pressure-sensitive device that provides a visual indication of excessive pressure in lubrication systems. Its primary function is to detect and signal blockages or overpressure conditions, helping to protect equipment and facilitate troubleshooting. The part is typically constructed from robust materials suitable for high-pressure industrial environments, though the specific material is not always specified in available documentation.

Key Features:

• Rupture Indicator
• 1/8-27 NPTF
• 4600 psi (317 bar)
• Trabon series progressive divider valves (MH, MS, MXP, MX, MJ, MGO, etc.)
• Pressure-sensitive device for detecting excessive system pressure
• Visual indication of blockage or overpressure (pin protrudes upon rupture)
• Compact design for easy installation and maintenance
• Helps protect lubrication systems from damage due to blockages
• Facilitates quick troubleshooting and minimizes downtime

Applications:
Used in industrial lubrication systems, particularly where system pressures may exceed 2,500 psi (172 bar), to protect equipment and provide clear visual indication of blockages or overpressure conditions. Commonly installed on MH divider valve applications and other Trabon series valves in mining, manufacturing, and heavy equipment environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system. Non-genuine parts may not provide the same level of protection or may fail prematurely.
• Ensure the system is depressurized before installation or maintenance
• Follow manufacturer guidelines for torque and sealing to prevent leaks
• Regularly inspect the rupture indicator for signs of activation or wear
• Replace the disc and reset the indicator pin after a rupture event
• Consult the equipment manual for specific installation procedures
