The GRACO 178543 is a female packing gland made from stainless steel. It is a sealing component designed to secure and compress packing materials within GRACO displacement pumps, ensuring leak-free operation and maintaining pump integrity.

Key Features:

• Packing gland (female)
• Stainless steel
• Compatible with GRACO 1:1 Fast-Flo pumps and various displacement pump models (e.g., included in repair kits for models 226951, 237449, and others)
• Stainless steel construction for durability and corrosion resistance
• Designed for easy replacement and maintenance
• Essential for maintaining pump seal integrity and preventing leaks

Applications:
Used in GRACO displacement pumps and 1:1 Fast-Flo pumps for sealing and compressing packing materials, ensuring reliable pump operation in industrial lubrication and fluid transfer applications.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of the pump assembly.
• Ensure the packing nut is left loose until the displacement rod is installed, then tighten just enough to prevent leaking—overtightening can damage packings.
• Follow manufacturer instructions for disassembly and reassembly to avoid shearing of packings.
• Regularly inspect and replace packing glands as part of routine maintenance to prevent leaks and maintain pump efficiency.
