The GRACO 24N320 is a repair kit containing an overmolded PTFE/EPDM diaphragm designed for use in Husky 515 and 716 air-operated diaphragm pumps. The kit is intended to restore or maintain the performance of these pumps by replacing worn or damaged diaphragms. The PTFE/EPDM construction provides chemical resistance and durability for demanding industrial applications.

Key Features:

• Diaphragm repair kit
• For 1/2-inch pumps (Husky 515/716)
• Overmolded PTFE/EPDM
• Husky 515 and 716 air-operated diaphragm pumps
• Chemical resistance due to PTFE/EPDM construction
• Designed for easy replacement and maintenance
• Reliable performance in harsh environments
• Overmolded design enhances durability and service life

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

Installation Notes:

• Using genuine GRACO parts ensures optimal pump performance, safety, and longevity.
• Relieve all pressure before disassembly
• Follow the manufacturer’s assembly order for diaphragm, backup diaphragm (if applicable), and plates
• Ensure the 'AIR SIDE' marking faces the correct direction as per manual instructions
• Apply medium-strength (blue) thread locker to the threads of the fluid-side diaphragm plate
• Handle the diaphragm shaft carefully to avoid damaging u-cups during installation
• Torque screws to 35–45 in-lb (4.0–5.1 N-m) when reassembling air covers
