The GRACO 563191 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
• 2350 psi
• Designed for use with GRACO divider valve applications and compatible with systems where lube pressures may exceed 2,500 psi
• Provides visual indication of excessive system pressure
• Rupture disc vents lubricant to atmosphere at set pressure
• Helps protect pumps and system components from overpressure
• Easy to replace and reset after activation

Applications:
Used in industrial lubrication systems, particularly those with divider valve applications where lube system pressures may exceed 2,500 psi. Commonly found in mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in high-pressure systems.
• Ensure system is depressurized before installation or replacement
• Tighten to recommended torque (for similar indicators, GRACO recommends tightening to 5 ft-lbs, but always check specific product documentation)
• Inspect and replace the rupture disc after activation
• Reset indicator pin manually after maintenance
• Regularly inspect indicator for signs of activation or wear
• Replace with genuine GRACO parts to maintain system integrity
• Follow all safety procedures when working with high-pressure systems
