This part is intended for use within GRACO equipment to ensure secure fastening and prevent loosening under vibration or load.

Key Features:

• Belleville Washer
• Designed for use in GRACO equipment; consult manual for specific models
• Provides axial force to maintain bolt tension
• Helps prevent loosening due to vibration or load
• Compact size for use in tight spaces

Applications:
Used in GRACO equipment assemblies where secure fastening and resistance to vibration or load loosening are required.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and reliability within GRACO equipment.
• Ensure the washer is installed with the correct orientation (convex side typically facing the bolt head or nut)
• Tighten bolts to the recommended torque specified in the equipment manual
• Inspect for wear or deformation before installation and replace if necessary
• Regularly inspect washers for signs of wear, corrosion, or deformation
