The GRACO U60977 ROD, PISTON, PR70 is a critical component used in GRACO’s PR70 series of air-operated equipment, particularly in paint sprayers and two-component liquid dispensing systems. It is typically constructed from durable materials such as stainless steel or nylon, depending on the specific model and application. Its primary function is to facilitate the precise movement and sealing of the piston within the air cylinder, ensuring accurate metering and dispensing of fluids.

Key Features:

• Rod and piston assembly
• PR70 series (specific to PR70A and related models)
• Stainless steel or nylon (varies by model and application)
• Up to 3000 psi (21 MPa, 207 bar) maximum working pressure for PR70 systems
• Compatible with GRACO PR70, PR70A, and PR70v equipment
• Designed for reliable, high-precision piston movement
• Facilitates accurate metering and dispensing of two-component materials
• Supports easy maintenance and replacement
• Robust construction for industrial environments

Applications:
Used in GRACO PR70 series equipment for accurate metering, mixing, and dispensing of two-component materials such as paints, adhesives, and coatings. Suitable for professional and industrial use in environments requiring precise fluid control.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise system integrity and void warranties.
• Always refer to the GRACO PR70 manual for specific installation instructions
• Ensure the shaft seal is installed with the open side facing away from the piston rod entry
• Verify compatibility with your specific PR70 model before installation
• Follow all safety instructions and warnings provided in the manual
