The GRACO 24K899 is a replacement diaphragm kit featuring PTFE (polytetrafluoroethylene) overmolded diaphragms, designed for use in GRACO air-operated double diaphragm (AODD) pumps. The kit is engineered to provide reliable sealing and chemical resistance, making it suitable for handling a wide range of fluids in industrial applications.

Key Features:

• Diaphragm Kit
• 24K899 (for 3-inch pump, specifically referenced for Husky 3300 GRACO Pump)
• PTFE overmolded diaphragms (material may vary by kit; some references mention PTFE/EPDM, but primary listing is PTFE overmolded)
• Husky 3300 GRACO Pump (3-inch AODD pump)
• Overmolded PTFE diaphragms for enhanced chemical resistance and durability
• Includes installation tools and sealant for ease of maintenance
• Designed for reliable performance in demanding industrial environments

Applications:
Used in industrial fluid transfer applications where chemical resistance and reliable sealing are required, such as in chemical processing, mining, and agriculture.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the pump.
• Follow the manufacturer’s instructions for diaphragm replacement
• Use the included installation tool and sealant for proper assembly
• Inspect all components for wear or damage before installation
• Ensure the pump is depressurized and isolated from the system before servicing
