The GRACO 17E794 is an inlet valve cap, typically constructed from durable materials such as metal or engineered plastics, designed to secure and seal the inlet valve assembly in GRACO Z-Series chemical pumps. Its primary function is to maintain system integrity and prevent leaks during operation.

Key Features:

• Inlet valve cap
• GRACO Z-Series chemical pumps (e.g., S1, S3, S4, and other Z-Series models)
• Secures and seals inlet valve assembly
• Essential for maintaining pump integrity
• Designed for reliable performance in demanding environments

Applications:
Used in GRACO Z-Series chemical pumps for applications requiring precise and reliable chemical transfer, such as lubrication, maintenance, and industrial fluid handling.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of the pump system.
• Apply anti-seize lubricant to threads before installation
• Torque inlet valve cap to specified value (e.g., 70 ft-lbs/95 N•m for S4 models)
• Ensure O-rings are properly seated and in good condition
• Follow manufacturer’s assembly instructions for correct orientation and tightening sequence
• Regularly inspect for wear or damage
• Replace O-rings and seals as needed during maintenance
• Use only recommended tools and torque specifications
