The GRACO 563218 is a replacement rupture-to-atmosphere indicator designed for use in high-pressure lubrication systems. It is typically constructed from robust materials suitable for industrial environments and is intended to provide pump protection by venting lubricant to the atmosphere when system pressure exceeds a predetermined threshold, thereby preventing equipment damage.

Key Features:

• Rupture-to-Atmosphere Indicator
• 1/8 in NPTF
• 6400 psi (441 bar)
• Used with GRACO divider valve applications and high-pressure lubrication systems
• Provides visual indication of excessive system pressure
• Vents lubricant to atmosphere to relieve high pressure
• Designed for easy replacement and maintenance
• Reliable operation in demanding industrial environments

Applications:
Used in MH divider valve applications and other high-pressure lubrication systems where system pressures exceed 2,500 psi. Commonly found in industrial, mining, and agricultural equipment requiring reliable pump protection and pressure relief.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure the system is depressurized before installation or replacement
• Tighten to recommended torque specifications (for similar indicators, GRACO recommends tightening to 5 ft-lbs, but always verify with current documentation for this specific part)
• Inspect the indicator and surrounding components for wear or damage during maintenance
• Replace the indicator if the rupture disc has been activated
• Regularly inspect the indicator for signs of activation or leakage
• Follow manufacturer guidelines for replacement intervals and maintenance
• Use only genuine GRACO replacement parts for optimal system performance
