The GRACO 626044 is a stud, specifically a piston shaft stud, designed for use in GRACO positive displacement pumps and related equipment. Its main material is not explicitly stated in available sources, but it is a critical component for connecting and securing piston assemblies within the pump mechanism.

Key Features:

• Stud (Piston Shaft)
• Compatible with GRACO positive displacement pumps and related assemblies
• Critical for secure piston assembly connection
• Designed for reliability and durability in high-duty applications
• Ease of maintenance: replacement part for worn or damaged studs

Applications:
Used in GRACO positive displacement pumps and similar equipment for connecting piston assemblies, ensuring proper function and longevity of the pump system.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety, reducing the risk of equipment failure and downtime.
• Clean threads of the piston and connecting rod stud before installation.
• Apply Loctite® 242 or equivalent thread locker to both the piston and stud threads.
• Torque the stud into the piston to the specified value (148–162 ft-lb or 200–220 N·m, as per relevant GRACO manual).
• Ensure proper greasing of components for smooth operation and longevity.
