The GRACO 563219 is a replacement rupture-to-atmosphere indicator designed for use with MJ, MSP, MHH, and MXP divider valves. It is constructed for high-pressure lubrication systems and provides visual indication and protection by venting lubricant to the atmosphere when system pressure exceeds a predetermined threshold. The material is not specified, but it is intended for use with oil-based lubricants.

Key Features:

• Rupture-to-Atmosphere Indicator
• 1/8 in NPTF
• Maximum working pressure: 7300 psi (503 bar, 50300 kPa, 50.3 MPa)
• Compatible with MJ, MSP, MHH, and MXP divider valves
• Provides visual indication of excessive system pressure
• Vents lubricant to the atmosphere to relieve high pressure
• Designed for high reliability and pump protection
• Easy to replace and reset after activation

Applications:
Used in high-pressure lubrication systems, particularly where system pressures exceed 2,500 psi, to protect pumps and divider valves from overpressure conditions. Suitable for industrial machinery, mining, and agricultural equipment.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in high-pressure lubrication systems.
• Ensure correct thread type (1/8 in NPTF, female) and orientation
• Tighten to manufacturer-recommended torque (for similar indicators, typically 5 ft-lbs, but verify for this specific part)
• Inspect for leaks and proper seating after installation
• Replace the indicator after activation and reset the system as needed
• Regularly inspect for signs of activation or damage
• Replace the indicator immediately after it has ruptured
• Keep spare indicators on hand for quick replacement
• Follow manufacturer guidelines for system maintenance
