The GRACO 160940 Piston Coupling is a critical component designed to connect the piston body within GRACO Fire-Ball 300 pumps. Its material is not explicitly stated, but it is engineered for durability and reliable performance in high-pressure spray systems. The part is intended to ensure secure and efficient transfer of motion between the piston and the pump assembly.

Key Features:

• Piston Coupling
• Fits 15:1 Fire-Ball 300 Pumps (e.g., Model 206699 Series J, Model 206405 Series K)
• GRACO Fire-Ball 300 Pumps (15:1 ratio), including Model 206699 Series J and Model 206405 Series K
• Engineered for secure connection between piston and pump
• Designed for reliable operation in high-pressure environments
• Essential for maintaining pump efficiency and longevity

Applications:
Used in GRACO Fire-Ball 300 pumps for industrial and commercial spray applications, including undercoating and other high-pressure fluid delivery systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment, reducing the risk of equipment failure and downtime.
• Always refer to the specific GRACO pump manual for detailed installation instructions
• Ensure the pump is depressurized and disconnected from power before installation
• Inspect the coupling and surrounding components for wear or damage prior to installation
• Use appropriate tools and follow torque specifications as outlined in the manual
• Regularly inspect the piston coupling for signs of wear or damage
• Replace the coupling as part of routine maintenance or if performance issues arise
• Keep the pump and coupling clean from debris and contaminants
