The GRACO 556405 is a fitting designed for industrial lubrication equipment, featuring a 1/2 x 1/8 NPTF (National Pipe Taper Fuel) connection. Its intended use is to facilitate secure and leak-resistant connections between components in lubrication systems, commonly found in industrial and maintenance applications. The material is not explicitly stated, but similar GRACO fittings are typically made from brass or steel for durability and chemical resistance.

Key Features:

• Fitting
• 1/2 x 1/8 NPTF
• Industrial lubrication equipment, compatible with NPTF threaded connections
• Hexagonal (hex) design for easy installation and removal
• Red color for easy identification
• Leak-resistant NPTF thread for secure connections

Applications:
Used in industrial lubrication systems for connecting hoses, pumps, and other components in environments requiring reliable and secure fluid transfer.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape for NPTF connections to prevent leaks
• Tighten securely using a wrench on the hex portion to avoid damage to the fitting
• Regularly inspect fittings for signs of wear or leaks
• Replace fittings if damaged or if leaks are detected
• Follow manufacturer guidelines for maintenance intervals
