The GRACO 188257 SEAL, PISTON is a replacement piston seal designed for use in specific GRACO pumps, such as the 235540 model. It is a critical sealing component that ensures proper operation and prevents fluid leakage within the pump assembly. The material is not specified in available documentation, but it is engineered for durability and compatibility with industrial fluids.

Key Features:

• Piston Seal
• Designed for use in GRACO pump model 235540
• Critical sealing component for pump operation
• Engineered for durability and reliability
• Essential for preventing fluid leakage

Applications:
Used in industrial fluid handling and lubrication systems, particularly in GRACO pumps such as model 235540, where reliable sealing is required for efficient operation.

Installation Notes:

• Using genuine GRACO piston seals ensures proper fit, performance, and longevity of the pump, reducing the risk of leaks and equipment failure.
• Always refer to the specific pump manual for installation instructions
• Ensure the pump is depressurized and cleaned before replacing the seal
• Inspect the piston and cylinder for wear or damage before installing a new seal
• Lubricate the seal as recommended by the manufacturer to facilitate installation and prevent damage
• Regularly inspect seals for wear and replace as needed
