The GRACO A2000678 is a top piston screw designed for use in GRACO 1092 series dispensing valves. It is a threaded fastener (10-32 thread size) intended to secure the piston assembly within the valve. The material is not specified in available sources, but GRACO typically uses high-quality steel or alloy for such components. Its primary function is to maintain the integrity and alignment of the piston during operation, ensuring reliable performance in precision dispensing systems.

Key Features:

• Screw, Top Piston
• 10-32 thread
• GRACO 1092 series dispensing valves
• Precision-engineered for secure piston retention
• Designed for reliable operation in high-pressure dispensing systems
• Ease of maintenance and replacement

Applications:
Used in GRACO 1092 series valves for precise one-component micro-dispensing applications, commonly found in industrial fluid handling, lubrication, and maintenance systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise system reliability and void warranties.
• Ensure the valve is depressurized and isolated before installation.
• Use appropriate tools to avoid cross-threading or over-tightening.
• Follow the equipment manual for torque specifications and installation sequence.
• Inspect the screw and mating surfaces for damage or wear before installation.
