The GRACO 564059 is a rupture-to-atmosphere indicator designed to provide pump protection and visual indication of excessive system pressure. It is typically constructed from durable materials suitable for industrial environments and is intended for use within GRACO lubrication systems to prevent damage from overpressure by venting lubricant to the atmosphere when a predetermined pressure is exceeded.

Key Features:

• Rupture-to-Atmosphere Indicator
• 1/8 in NPTF
• Maximum working pressure: 1750 psi
• Used in conjunction with system pressure switches in GRACO lubrication systems
• Provides visual indication of excessive system pressure
• Vents lubricant to atmosphere to relieve high pressure
• Designed for reliability and ease of maintenance
• Standard on all GRACO pumps for pump protection

Applications:
Used in industrial lubrication systems where pump protection and overpressure indication are required, such as in mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and system reliability.
• Install in accordance with GRACO equipment manuals
• Ensure proper thread engagement for 1/8 in NPTF connections
• Check for leaks and proper operation after installation
• Replace indicator if disc has ruptured
• Regularly inspect for signs of disc rupture or leakage
• Replace indicator as needed to maintain system protection
• Reset or replace after any overpressure event
