The GRACO 189851 is an intake valve packing (seal) designed for use in GRACO pumps. It is a critical sealing component that ensures proper operation and prevents leaks within the intake valve assembly. The material is not specified in available sources, but such packings are typically made from durable elastomers or engineered plastics to withstand fluid exposure and mechanical wear. Its intended use is to maintain a tight seal in the intake valve of GRACO pump systems, supporting reliable fluid transfer and pump longevity.

Key Features:

• Intake valve packing/seal
• Compatible with select GRACO pump models (e.g., Check-Mate 1000 series)
• Ensures leak-free operation of intake valve
• Supports reliable pump performance
• Designed for easy replacement during maintenance

Applications:
Used in GRACO pump systems for fluid transfer applications, including lubrication, paint, and other industrial fluids. Suitable for industries such as mining, agriculture, and manufacturing where reliable pump operation is essential.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of the pump system.
• Refer to the specific GRACO pump manual for detailed installation instructions
• Ensure the intake valve is clean and free of debris before installing the packing
• Press the packing into the recess of the intake valve with the beveled side facing up (as per some GRACO manuals)
• Regularly inspect and replace the packing as part of routine maintenance to prevent leaks and maintain pump efficiency
