The GRACO 176638 is a V-packing seal designed for use in GRACO pumps and spray equipment. It is typically constructed from materials such as UHMWPE (Ultra-High Molecular Weight Polyethylene) or PTFE (Polytetrafluoroethylene), providing excellent wear resistance and chemical compatibility. Its primary function is to seal the piston or rod within the pump assembly, preventing fluid leakage and ensuring efficient operation.

Key Features:

• V-packing seal
• 176638
• UHMWPE or PTFE (varies by supplier; Bedford replacement is UHMWPE)
• Designed for GRACO pumps and spray equipment; compatible with models requiring part number 176638
• Wear-resistant material for long service life
• Reliable sealing performance
• Easy to replace during maintenance

Applications:
Used in GRACO pumps and spray equipment for sealing pistons or rods, suitable for transfer and supply of solventborne and waterborne finishing materials in professional settings.

Installation Notes:

• Using genuine or OEM-approved replacement parts ensures proper fit, performance, and longevity of the equipment.
• Ensure the pump is depressurized and isolated before replacing the packing
• Clean the piston or rod and packing gland area thoroughly before installation
• Follow the equipment manual for specific installation procedures and torque specifications
• Inspect the packing regularly and replace if signs of wear or leakage are observed
