The GRACO 563190 is a pressure relief device designed to protect lubrication systems from excessive pressure. It features a rupture disc that vents lubricant to the atmosphere when system pressure exceeds a predetermined threshold, providing both system protection and a visual indication of overpressure. The part is constructed for use with oil-based lubricants and is intended for integration into high-pressure lubrication equipment.

Key Features:

• Rupture-to-Atmosphere Indicator
• 1/4 in. NPTF
• 5500 psi (379 bar)
• Oil-based lubricants
• Visual indication of excessive system pressure
• Protects pumps and systems from overpressure
• Easy to reset and maintain after rupture
• Reliable operation in high-pressure environments

Applications:
Used in high-pressure lubrication systems for in-plant machinery, compressor equipment, and other industrial applications where system protection from overpressure is required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Install according to GRACO equipment manual specifications
• Ensure proper thread engagement and torque (disc tightening to 5 ft-lbs recommended for similar models)
• Regularly inspect and replace the rupture disc after activation
• Reset indicator pin after correcting system faults
• Monitor for visual indication of rupture
• Replace rupture disc and reset pin after each activation
• Check for leaks and proper system pressure after installation
