The GRACO 120905 is a hex lock nut with M5 X 0.8 thread, designed for secure fastening in GRACO spray equipment. The material is not explicitly specified in available sources, but similar nuts in the industry are typically made from steel or stainless steel. Its intended use is to provide a vibration-resistant locking mechanism for critical connections within GRACO spray systems.

Key Features:

• Hex Lock Nut
• M5 X 0.8
• Designed for use with GRACO spray equipment, specifically models such as PR70e and PR70v feed systems
• Vibration-resistant locking mechanism
• Standard hex profile for easy installation and removal
• Reliable fastening for critical equipment connections

Applications:
Used in GRACO spray equipment assemblies to secure components and prevent loosening due to vibration or movement.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and reliability of the equipment, reducing the risk of leaks or failures.
• Ensure threads are clean and undamaged before installation
• Tighten to the recommended torque for the application
• Inspect regularly for signs of wear or loosening
• Periodically check tightness, especially in high-vibration environments
• Replace if damaged or if locking feature is compromised
