The GRACO 563960 Blowout Disc Kit consists of 25 purple discs designed to act as safety components within GRACO lubrication systems. These discs are engineered to rupture at a specific pressure, providing a warning of system faults while allowing the lubrication system to continue operating safely. The material is not specified, but such discs are typically made from a durable, pressure-sensitive material suitable for industrial environments.

Key Features:

• Blowout Disc Kit
• 3/8 in. diameter, 25 pieces per kit
• 3250 psi (22,393 kPa) maximum working pressure
• Used with GRACO lubrication systems, specifically in conjunction with system pressure switches
• Provides early warning of system faults
• Allows continued safe operation of lubrication system
• Easy to replace as part of routine maintenance
• Reliable performance under high pressure

Applications:
Used in industrial lubrication systems to protect equipment from overpressure and to indicate system faults. Commonly installed in large-scale mining, manufacturing, and agricultural equipment where reliable lubrication is critical.

Installation Notes:

• Using genuine GRACO blowout discs ensures proper fit, reliable performance, and maintains system safety and warranty compliance.
• Install discs according to GRACO equipment manual instructions
• Ensure system is depressurized before replacing discs
• Regularly inspect discs for signs of wear or rupture
• Replace discs immediately if they have ruptured or show damage
