The GRACO 188784 is a hex jam nut, typically made from stainless steel, designed to secure and lock components in place within GRACO equipment, such as agitators and pressure tanks. Its primary function is to provide a reliable fastening solution in demanding industrial environments.

Key Features:

• Hex Jam Nut
• 1-1/2-12-UNF-2B
• Stainless steel (commonly used in GRACO agitators and tanks)
• Compatible with GRACO agitators and pressure tanks (e.g., 2-gallon, 5-gallon, 10-gallon, 15-gallon models)
• Hexagonal shape for easy tightening with standard tools
• Designed for secure fastening in high-vibration environments
• Durable stainless steel construction for corrosion resistance

Applications:
Used in GRACO agitators and pressure tanks to secure shafts, couplings, and other critical components. Suitable for industrial, agricultural, and mining applications where reliable fastening is essential.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and safety in equipment operation.
• Ensure threads are clean and undamaged before installation
• Tighten to recommended torque specifications (e.g., 50 ft-lb/68 N-m for some GRACO assemblies)
• Use appropriate tools to avoid rounding or damaging the nut
• Regularly inspect for wear or loosening in high-vibration environments
