The GRACO 240895 PISTON, ASSY is a piston assembly designed for use in GRACO automatic air-assisted spray guns. It is a critical internal component that facilitates the movement and control of the spray gun’s needle or valve mechanism. The material is not explicitly specified in available documentation, but GRACO piston assemblies are typically constructed from durable metals or engineered plastics for reliability and longevity. Its intended use is to ensure precise and consistent operation within GRACO spray equipment, particularly in industrial and commercial coating applications.

Key Features:

• Piston Assembly
• Compatible with GRACO automatic air-assisted spray guns (e.g., G40 series, PerformAA™ Auto Air Assist Spray Guns)
• Precision-engineered for reliable operation
• Designed for easy replacement and maintenance
• Supports consistent spray performance

Applications:
Used in GRACO automatic air-assisted spray guns for industrial and commercial coating applications, including automotive, manufacturing, and protective coatings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise spray quality and equipment reliability.
• Always follow the manufacturer’s installation instructions as outlined in the equipment manual.
• Ensure the spray gun is depressurized and disconnected from air and fluid supplies before installation.
• Inspect all related seals and O-rings for wear and replace if necessary.
• Lubricate threads and moving parts as recommended by GRACO.
• Tighten all components to the specified torque values to prevent leaks and ensure proper function.
• Regularly inspect the piston assembly for wear or damage.
• Replace the piston assembly and related seals as part of routine maintenance.
• Keep the assembly clean and free of debris to prevent malfunction.
• Consult the GRACO manual for specific maintenance intervals and procedures.
