The GRACO 178226 is a piston seal designed for use in GRACO hydraulic equipment, such as sprayers and line stripers. Its material is not explicitly specified in available documentation, but typical GRACO piston seals are made from durable elastomers or engineered plastics for reliable sealing and long service life. The seal is intended to prevent fluid leakage and maintain hydraulic pressure within the piston assembly.

Key Features:

• Piston Seal
• 178226
• Compatible with GRACO hydraulic sprayers and line stripers (see equipment manual for exact models)
• Designed for reliable sealing in high-pressure hydraulic systems
• Engineered for durability and long service life
• Supports smooth piston movement and prevents fluid leakage

Applications:
Used in GRACO hydraulic sprayers and line stripers to maintain hydraulic pressure and prevent fluid leakage within the piston assembly.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of equipment. Non-genuine parts may compromise system integrity and void warranties.
• Always follow the equipment manual for installation procedures
• Ensure the piston and seal surfaces are clean and free of debris before installation
• Use appropriate tools to avoid damaging the seal during installation
• Inspect the seal for wear or damage before installation and replace if necessary
