The GRACO 15G198 Nut, Packing 4 GPM is an OEM replacement part designed to secure and seal packing components within GRACO displacement pumps. Its material is not explicitly stated, but it is typically constructed from durable metal to withstand high-pressure environments. This nut is essential for maintaining the integrity of the pump’s packing assembly, ensuring proper sealing and preventing leaks during operation.

Key Features:

• Nut, Packing
• 4 GPM
• 4 GPM
• GRACO displacement pumps (specific models not listed)
• OEM quality for reliability
• Designed for ease of maintenance and replacement
• Ensures proper sealing of pump packing

Applications:
Used in GRACO displacement pumps for sealing and securing packing components, commonly found in lubrication, paint, and fluid transfer systems.

Installation Notes:

• Using genuine GRACO parts like the 15G198 ensures optimal performance, longevity, and safety of the equipment. Non-genuine parts may compromise sealing and lead to leaks or equipment failure.
• Torque the packing nut to the manufacturer’s recommended specification (for similar GRACO displacement pumps, torque is typically 50 ft-lb or 68 N•m)
• Ensure the pump is depressurized and properly cleaned before installation
• Follow the equipment manual for specific installation procedures
