The GRACO 15Y231 is a piston/throat seal designed for use in GRACO 120 series pumps. It is typically made from durable elastomeric or composite materials engineered for high-pressure and high-wear environments. This seal ensures proper sealing between the piston and throat, preventing leaks and maintaining pump efficiency in lubrication and fluid transfer applications.

Key Features:

• Piston/Throat Seal
• For GRACO 120 Pump
• GRACO 120 series pumps
• Engineered for high-pressure and high-wear environments
• Designed for reliable sealing and long service life
• Supports efficient pump operation and reduced maintenance

Applications:
Used in lubrication and fluid transfer systems, particularly in industrial and agricultural equipment requiring reliable sealing in high-pressure pumps.

Installation Notes:

• Using genuine GRACO seals ensures optimal performance, compatibility, and longevity of the pump. Non-genuine parts may compromise seal integrity and pump efficiency.
• Follow the pressure relief procedure as outlined in the GRACO pump manual before installation
• Ensure the pump is depressurized and isolated from the system before replacing the seal
• Inspect the piston and throat for wear or damage before installing the new seal
• Lubricate the seal as recommended by GRACO to facilitate installation and prevent premature wear
