The GRACO 222438 Q ROD, PISTON is a critical component designed to ensure smooth and reliable operation within GRACO airless paint sprayers and displacement pumps. It is typically constructed from durable materials such as hardened steel or similar alloys to withstand the mechanical stresses of high-pressure pumping applications. Its primary function is to transmit force from the pump motor to the piston, enabling the movement necessary for fluid transfer in spray equipment.

Key Features:

• Piston Rod
• Durable metal (likely hardened steel or alloy)
• Fits GRACO Ultra 750, Ultra 1000, GM 3500, EM 590, and other compatible models (always verify with your equipment manual)
• Engineered for smooth operation and long service life
• Designed to meet GRACO’s high standards for reliability and performance
• Ease of maintenance when used with genuine GRACO parts

Applications:
Used in GRACO airless paint sprayers and displacement pumps for transferring paint or other fluids under high pressure.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise equipment function and void warranties.
• Always verify part compatibility with your specific GRACO equipment model before installation
• Follow the equipment manual for step-by-step installation instructions
• Inspect the rod and related components for wear or damage before installation
• Keep spare parts and repair kits on hand to minimize downtime
