The GRACO 563193 is a replacement rupture-to-atmosphere indicator designed for use in high-pressure lubrication systems. It is constructed to provide pump protection and visual indication of excessive system pressure. When system pressure exceeds the set threshold, the pressure disc ruptures, venting lubricant to the atmosphere and relieving high pressure. The intended use is within GRACO equipment, specifically in applications where lube system pressures may exceed safe operating limits. Material is not specified.

Key Features:

• Rupture-to-Atmosphere Indicator
• 1/8 in NPTF
• 3250 psi (224 bar)
• Designed for use with GRACO lubrication systems and compatible with oil-based lubricants
• Provides visual indication of excessive system pressure
• Protects pumps and system components from overpressure
• Pressure disc ruptures at predetermined setting
• Easy to replace and reset after activation

Applications:
Used in industrial lubrication systems, particularly where lube system pressures may exceed safe operating limits. Commonly installed on GRACO pumps and divider valve applications to protect equipment from damage due to overpressure.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and reliability, maintaining system integrity and safety.
• Ensure system is depressurized before installation or replacement
• Use appropriate tools to tighten to recommended torque (for similar indicators, GRACO recommends tightening to 5 ft-lbs, but always check specific documentation for this part)
• Inspect for leaks after installation
• Replace the indicator after activation and reset as needed
• Regularly inspect for signs of activation or damage
• Replace the indicator after each activation event
• Follow manufacturer guidelines for maintenance and replacement intervals
