• Maximum solid size: 2.4 mm (0.2383 cm)
• Operating temperature range: 4°C to 107°C (40°F to 225°F)

Applications:
Used in applied fluid technology, process oil and natural gas, lubrication systems, and by contractors and DIY users for reliable fluid transfer in demanding environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• Ensure correct air and fluid connections (1/4" air inlet, 3/4" fluid inlet/outlet)
• Follow manufacturer guidelines for pressure and temperature limits
• Regularly inspect and maintain the diaphragm, ball checks, and air valve for optimal performance
• Use appropriate safety measures when handling industrial fluids
