The GRACO Packing Nut (SKU:. 197641) is a hardware component designed to secure and compress packing material within GRACO spray equipment. Its primary function is to maintain a proper seal around moving parts, such as rods or pistons, to prevent fluid leakage and ensure reliable operation. The material is typically metal (often steel or brass) for durability and corrosion resistance, but specific material is not explicitly stated in available sources.

Key Features:

• Packing Nut
• Designed for use with GRACO spray equipment; consult manual for specific models
• Secures and compresses packing material to prevent leaks
• Designed for easy installation and maintenance
• Enhances equipment reliability and longevity

Applications:
Used in GRACO spray equipment to maintain seals and prevent fluid leakage during operation. Suitable for industrial, agricultural, and maintenance applications where reliable fluid handling is required.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of the equipment. Non-genuine parts may compromise seal integrity and equipment reliability.
• Ensure the packing nut is tightened to the manufacturer’s recommended torque or drag force (e.g., for similar GRACO parts, a drag force of 3 lb/13.3N is specified when sliding the packing housing assembly along the rod)
• Inspect packing material for wear before installation
• Follow equipment manual for specific installation procedures
