The GRACO 17J187 O-RING is a specialized sealing component designed to provide a tight and secure seal within GRACO equipment, specifically for the piston seat in certain displacement pumps. The material is not explicitly stated in available documentation, but GRACO commonly uses materials such as PTFE, nylon, or other elastomers for similar o-rings. Its intended use is to prevent leaks and ensure reliable operation of the pump assembly.

Key Features:

• O-Ring
• 17J187
• Compatible with GRACO displacement pumps, including ProConnect Express and Pro-Duty models
• Designed for reliable sealing in high-pressure environments
• Essential for maintaining pump integrity and preventing leaks
• Engineered for ease of maintenance and replacement

Applications:
Used in GRACO displacement pumps, such as the ProConnect Express and Pro-Duty series, to seal the piston seat and ensure leak-free operation.

Installation Notes:

• Using a genuine GRACO 17J187 O-RING ensures proper fit, seal integrity, and equipment reliability. Non-genuine parts may compromise performance and safety.
• Grease the o-ring before installation to facilitate placement and reduce friction
• Place the o-ring in the designated groove on the piston seat or intake valve housing as specified in the manual
• Inspect the o-ring for damage or wear before installation and replace if necessary
• Follow all safety and maintenance procedures outlined in the GRACO equipment manual
