The GRACO 18B144 is a diagnostic port coupling designed for use in hydraulic systems. It is typically constructed from durable materials suitable for hydraulic applications, and its primary function is to provide a connection point for diagnostic equipment to monitor or service hydraulic components within GRACO equipment.

Key Features:

• Coupling, Hydro Diagnostic Port
• 18B144
• Designed for use with GRACO hydraulic equipment; specific compatibility should be verified with the equipment manual
• Provides a secure connection for diagnostic tools
• Facilitates maintenance and troubleshooting of hydraulic systems
• Reliable performance in demanding environments

Applications:
Used in hydraulic systems for diagnostic and maintenance purposes, particularly in GRACO equipment such as the GrindLazer models (e.g., 25P471, 25P472) where it is listed as a diagnostic port.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of hydraulic systems.
• Ensure the hydraulic system is depressurized before installation or removal
• Follow the equipment manual for specific installation instructions
• Inspect the coupling and port for damage or contamination before installation
• Regularly inspect the diagnostic port for leaks or wear
• Clean the port and coupling before connecting diagnostic equipment
• Replace the coupling if signs of damage or excessive wear are present
