The GRACO 557436 is a replacement rupture disk made of aluminum, designed for use in high-pressure lubrication systems. It acts as a safety device, rupturing at a set pressure to protect equipment from overpressure and to indicate system faults while allowing critical lubrication to continue.

Key Features:

• Rupture Disk
• 11/16 in
• Aluminum
• 2350 psi (maximum working pressure)
• Designed for use with GRACO lubrication systems and pressure switches
• Acts as a performance indicator for system faults
• Allows lubrication system to continue delivering to critical bearings during a fault
• Reliable safety device for high-pressure applications

Applications:
Used in industrial lubrication systems, particularly where system pressures may exceed safe limits and where continuous lubrication to critical bearings is essential.

Installation Notes:

• Using genuine GRACO replacement parts ensures proper fit, function, and safety in high-pressure lubrication systems.
• Install in accordance with GRACO equipment manual instructions
• Ensure proper alignment and secure fit to prevent leaks or premature rupture
• Regularly inspect for signs of wear or damage and replace as needed
