The GRACO 563953 is a replacement blowout disc kit designed for use in lubrication systems. It is made from an unspecified material and is intended to function as a safety component that ruptures at a specific pressure, warning of system faults while allowing continued lubrication to critical bearings.

Key Features:

• Blowout Disc Kit
• 1175/2800 PSI, 3/8" Diameter, Green
• 1175 PSI (rupture pressure), 2800 PSI (maximum system pressure)
• For use with 1/8" NPTF rupture-to-atmosphere indicators
• Easily replaceable discs
• Sold in packages of 25
• Used in conjunction with system pressure switch for fault warning
• Allows continued lubrication to critical bearings during fault conditions

Applications:
Used in industrial lubrication systems to protect equipment by providing a visual and mechanical indication of system overpressure, while maintaining lubrication to critical components.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in lubrication systems.
• Replace discs as part of routine maintenance or after a rupture event
• Ensure compatibility with 1/8" NPTF rupture-to-atmosphere indicators
• Follow system-specific installation procedures as outlined in the equipment manual
