The GRACO 563226 is a rupture indicator designed for use in high-pressure lubrication systems. It is constructed for compatibility with oil and is intended to detect and indicate excessive pressure caused by blockages in MH divider valve applications. When pressure exceeds the set limit, a disc ruptures, forcing an indicator pin to protrude and alerting operators to the blockage. The part is essential for protecting equipment from damage due to overpressure.

Key Features:

• Rupture Indicator
• 1/8-27 NPSF with O-Ring
• 6400 psi (441 bar)
• Oil
• High-pressure disc rupture mechanism
• Indicator pin for visual blockage detection
• O-ring for secure sealing
• Engineered for heavy-duty, lasting performance
• Easy to reset and replace after activation

Applications:
Used on MH divider valve applications where lube system pressures exceed 2,500 psi (172 bar), commonly found in in-plant machinery and compressor equipment.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems, minimizing downtime and repair delays.
• Ensure the system is depressurized before installation
• Check O-ring for integrity before assembly
• Follow manufacturer torque specifications for threaded connections
• Reset indicator pin and replace rupture disc after each activation
• Regularly inspect for signs of wear or leakage
• Perform preventative maintenance to ensure peak performance and longevity
• Keep spare rupture discs and indicator pins on hand for quick replacement
• Consult the equipment manual for specific installation and maintenance procedures
