The GRACO 904029 Ball Kit is a replacement part designed for GRACO fluid pressure regulators used in high-pressure mastic applications. It consists of a ball and seat, constructed from carbon steel, and is intended to restore or maintain the sealing and pressure regulation functions within GRACO mastic fluid regulators.

Key Features:

• Ball Kit (Ball and Seat)
• Carbon Steel
• For use with GRACO Mastic Fluid Regulators
• Designed for easy replacement and maintenance
• Reliable sealing for high-pressure mastic applications
• Durable carbon steel construction for long service life

Applications:
Used in high-pressure mastic fluid regulation systems, typically in industrial and construction settings where precise control of mastic or semi-solid material flow is required.

Installation Notes:

• Using genuine GRACO replacement parts ensures optimal performance, safety, and longevity of the regulator system.
• Ensure the regulator is depressurized and isolated from the system before replacement
• Follow GRACO’s recommended procedures for disassembly and reassembly
• Inspect the regulator seat and surrounding components for wear or damage during replacement
• Use appropriate tools and personal protective equipment
• Regularly inspect the ball and seat for wear or damage
• Replace the ball kit as part of scheduled maintenance or when leaks or pressure regulation issues are detected
• Keep replacement parts on hand to minimize downtime
