The GRACO 188178 SEAL, PISTON, 12:1 is a replacement piston seal designed for use in GRACO equipment, specifically for 12:1 ratio piston pumps. The material is not specified in available listings, but similar GRACO piston seals are typically made from durable materials such as acetal, PTFE, nitrile, or UHMWPE for high-pressure and sanitary applications. Its intended function is to ensure a reliable seal within the piston assembly, maintaining pump efficiency and preventing leaks in demanding industrial environments.

Key Features:

• Piston Seal
• 12:1 Ratio
• Designed for GRACO 12:1 ratio piston pumps
• Engineered for reliability and long service life
• Designed for easy replacement and maintenance
• Suitable for high-pressure and demanding industrial environments

Applications:
Used in industrial fluid handling systems, including lubrication, chemical transfer, and sanitary applications where GRACO 12:1 ratio piston pumps are employed.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Always follow the equipment manual for installation procedures
• Inspect the seal and mating surfaces for damage before installation
• Ensure proper lubrication of the seal during installation to prevent premature wear
• Check for correct orientation and seating of the seal within the piston assembly
• Regularly inspect seals for wear or damage
• Replace seals at recommended intervals or when leaks are detected
• Use only compatible lubricants and cleaning agents
