The GRACO 258773 is a cylinder O-ring kit designed for use in GRACO Z-Series chemical pumps. It contains O-rings and related components necessary for sealing and maintaining the cylinder assembly in pumps with capacities from 100cc to 160cc. The kit is intended to ensure reliable sealing and prevent leaks in high-pressure fluid handling applications.

Key Features:

• Cylinder O-ring kit
• 100-160cc (for Z-Series pumps)
• Rubber O-rings and related sealing components
• GRACO Z-Series chemical pumps (100cc, 105cc, 120cc, 140cc, 150cc, 160cc models)
• Essential for maintaining pump integrity and preventing leaks
• Supports reliable operation in demanding industrial environments
• Easy to install and replace during routine maintenance

Applications:
Used in industrial fluid handling systems, including chemical transfer, lubrication, and maintenance applications where GRACO Z-Series pumps are employed.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the pump system.
• Always follow the manufacturer’s guidelines for disassembly and reassembly of the pump cylinder
• Inspect all O-rings and related components for wear or damage before installation
• Ensure proper lubrication of O-rings during installation to prevent premature failure
• Use appropriate tools to avoid damaging sealing surfaces
• Regularly inspect O-rings and seals for signs of wear or degradation
• Replace O-rings as part of scheduled maintenance or at the first sign of leakage
• Keep spare kits on hand to minimize downtime during maintenance
