The GRACO 181978 is a piston seal made from UHMWPE (Ultra-High Molecular Weight Polyethylene), designed to provide a reliable sealing solution within GRACO air-powered Glutton pumps. Its primary function is to prevent fluid leakage and maintain pressure integrity between moving parts in the pump assembly.

Key Features:

• Piston Seal
• UHMWPE (Ultra-High Molecular Weight Polyethylene)
• Designed for use in GRACO air-powered Glutton pumps
• High wear resistance
• Chemical resistance
• Low friction for smooth operation
• Long service life

Applications:
Used in GRACO air-powered Glutton pumps for sealing pistons and preventing fluid leakage in industrial fluid transfer applications.

Installation Notes:

• Using genuine GRACO piston seals ensures optimal performance, reliability, and longevity of the pump. Non-genuine parts may compromise seal integrity and pump efficiency.
• Ensure all mating surfaces are clean and free of debris before installation.
• Follow the manufacturer’s recommended installation sequence and torque specifications.
• Inspect the seal for damage prior to installation.
• Refer to the equipment manual for detailed installation instructions.
