The GRACO 563959 Blowout Disc Kit consists of 25 blue rupture discs designed for use in high-pressure lubrication systems. These discs are engineered to act as safety devices, rupturing at a specified pressure to protect equipment from overpressure conditions. They are typically used in conjunction with system pressure switches to warn of faults while allowing the system to continue delivering lubrication to critical bearings.

Key Features:

• Rupture Disk
• 3/8 inch (0.375 inch) diameter
• Rupture at 2950 psi; Maximum working pressure: 7300 psi (note: this may refer to the system or related components, not the disc itself)
• For use with 1/8" NPTF rupture-to-atmosphere indicators
• Acts as a safety device to protect equipment from overpressure
• Easy to replace, allowing for quick system reset
• Used in conjunction with pressure switches for fault indication
• Reliable performance in demanding industrial environments

Applications:
Used in industrial lubrication systems to protect against overpressure, particularly in applications where continuous lubrication is critical, such as in mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in high-pressure systems.
• Replace the rupture disc after any overpressure event to restore system operation
• Ensure compatibility with 1/8" NPTF rupture-to-atmosphere indicators
• Follow all safety procedures when working with high-pressure systems
• Regularly inspect and replace discs as part of routine maintenance
