The GRACO 15B078 is a piston bushing designed for use in GRACO displacement pumps. It is a precision-engineered component that helps guide and support the piston within the pump assembly, ensuring smooth operation and reducing wear. The specific material is not explicitly stated in available sources, but GRACO piston bushings are commonly made from durable materials such as ultra-high molecular weight polyethylene (UHMWPE), brass, or other wear-resistant alloys, depending on the application.

Key Features:

• Piston bushing
• .296/255.79
• Designed for GRACO displacement pumps (e.g., Reactor series); compatible with specific pump models as referenced in GRACO manuals
• Precision fit for smooth piston movement
• Reduces wear and extends pump life
• Engineered for reliability in demanding applications

Applications:
Used in GRACO displacement pumps for fluid transfer and spray applications, commonly found in industrial, agricultural, and maintenance settings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment. Non-genuine parts may compromise pump efficiency and reliability.
• Always refer to the specific GRACO pump manual for installation instructions
• Ensure the pump is depressurized and isolated before replacing the bushing
• Inspect the piston and bushing bore for wear or damage before installation
• Lubricate the bushing and piston as recommended by GRACO
• Regularly inspect the bushing for signs of wear or damage
• Replace the bushing as part of scheduled maintenance or when excessive wear is detected
• Use only GRACO-approved lubricants and replacement parts
