The GRACO 563186 is a rupture-to-atmosphere indicator designed for use in lubrication systems. It is typically constructed from robust materials suitable for industrial environments and is intended to provide visual indication and relief of excessive system pressure, protecting pumps and equipment from damage due to blocked lines or high pressure.

Key Features:

• Rupture-to-Atmosphere Indicator
• 1/4 in. NPTF
• 1450 psi (100 bar)
• Designed for use with GRACO lubrication systems and divider valves
• Provides visual indication of excessive system pressure
• Relieves high pressure by venting lubricant to the atmosphere
• Easy to identify blocked lines or high system pressure
• Includes spud assembly for secure installation
• Reliable pump protection

Applications:
Used in industrial lubrication systems to protect pumps and equipment from damage caused by blocked lines or excessive pressure. Commonly installed on divider valves and other critical points in lubrication circuits.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure the system is depressurized before installation
• Use appropriate tools to tighten the indicator to recommended torque (for similar indicators, GRACO recommends tightening to 5 ft-lbs, but always check the specific manual for this part)
• Regularly inspect the indicator for signs of rupture or leakage
• Replace the rupture disc and reset the indicator after any activation
• Follow manufacturer guidelines for installation and maintenance
• Use only GRACO-approved replacement parts
• Monitor system pressure and inspect indicators during routine maintenance
