The GRACO 557122 COVER, HP SHAFT END is a protective component designed to cover the shaft end of high-pressure lubricators, such as the HP50 and HP60 models. Its primary function is to safeguard the shaft and internal mechanisms from environmental contaminants and physical damage. The material is not explicitly stated in available documentation, but similar covers for GRACO high-pressure lubricators are typically made from robust materials such as cast iron or heavy-duty plastics, depending on the specific model and application.

Key Features:

• Cover
• HP Shaft End (for HP50/HP60 High Pressure Lubricators)
• Compatible with GRACO HP50 and HP60 High Pressure Lubricators
• Protects shaft end from contaminants and physical damage
• Designed for easy installation and maintenance
• Reliable fit for long-term use

Applications:
Used in high-pressure lubrication systems for industrial machinery, including mining, manufacturing, and heavy equipment maintenance. Specifically designed for GRACO HP50 and HP60 High Pressure Lubricators.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, optimal protection, and reliable performance, reducing the risk of equipment failure and downtime.
• Ensure the equipment is powered off and depressurized before installation
• Align the cover properly with the shaft end before securing
• Use the recommended screws (e.g., #4 X .187 pan head self tap) for secure attachment
• Regularly inspect the cover for signs of wear or damage and replace as needed
