Key Features:

• Pressure gauge
• 1/4" NPT
• Brass
• 0 to 3000 PSI (0 to 206.8 bar)
• Medium-duty pumps and metering lubrication equipment
• Center back mount for easy installation and visibility
• Dry (non-liquid filled) gauge for standard environments
• Robust brass construction for durability
• Reliable pressure monitoring for system safety

Applications:
Used in industrial lubrication systems, particularly with GRACO medium-duty pumps and metering equipment, to monitor and maintain safe operating pressures.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of your lubrication system.
• Ensure the system is depressurized before installation
• Use appropriate thread sealant for NPT connections
• Mount the gauge in a visible location for easy monitoring
• Regularly inspect the gauge for signs of wear or damage
• Periodically check gauge accuracy and calibration
