The GRACO 563188 is a rupture-to-atmosphere indicator designed for use in high-pressure lubrication systems. It is 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
• 1/4 in. NPTF
• Maximum Working Pressure: 2350 psi (162 bar)
• Designed for use with GRACO lubrication systems and divider valve applications where lube system pressures exceed 2500 psi
• Provides visual indication of excessive system pressure
• Pressure disc ruptures at a predetermined setting to vent lubricant and relieve high pressure
• Includes spud assembly for secure installation
• Designed for reliability and ease of maintenance (disc and pin can be replaced/reset manually after activation)

Applications:
Used in industrial lubrication systems, particularly on MH divider valve applications where lube system pressures exceed 2500 psi. Suitable for mining, agriculture, and other heavy-duty environments requiring robust pump protection.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper torque is applied during installation (for similar indicators, GRACO recommends tightening to 5 ft-lbs)
• Install in accordance with GRACO equipment manuals and system requirements
• After activation, replace the rupture disc and reset the indicator pin manually
• Regularly inspect for signs of wear or damage
