The GRACO 551387 is a fluid pressure gauge designed for bottom mount installation with a 1/4 NPT connection. It is typically constructed from robust materials suitable for industrial environments and is intended for monitoring fluid pressure in GRACO equipment, such as mix manifolds and high-pressure spray systems.

Key Features:

• Pressure gauge
• 551387
• Compatible with GRACO mix manifolds and high-pressure systems; can be used in ports as a gun pressure gauge
• 1/4 NPT bottom mount for secure installation
• Designed for high-pressure industrial environments
• Reliable pressure monitoring for critical applications

Applications:
Used for monitoring fluid pressure in GRACO mix manifolds, high-pressure spray systems, and other industrial fluid handling equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety in high-pressure applications.
• Ensure proper thread engagement and sealing for 1/4 NPT connections
• Install in a location that allows for easy reading and maintenance
• Follow all safety guidelines for high-pressure equipment installation and operation
• Regularly inspect for leaks or damage
• Calibrate as needed to maintain accuracy
• Replace if signs of wear or malfunction are present
