The GRACO 108543 is a U-cup packing, a sealing component designed to prevent leakage and maintain pressure within GRACO sanitary pumps. It is typically made from materials such as UHMWPE or PTFE, depending on the specific pump model, and is intended for use in the sealing assembly of GRACO SaniForce™ 12:1 Sanitary Pumps and similar equipment.

Key Features:

• U-cup packing
• 108543
• UHMWPE or PTFE (varies by model)
• GRACO SaniForce™ 12:1 Sanitary Pumps and compatible models
• Designed for reliable sealing in sanitary pump applications
• Ease of maintenance and replacement
• Durable construction for extended duty cycles

Applications:
Used in sanitary pump assemblies to prevent leakage and maintain system integrity, suitable for food, beverage, pharmaceutical, and chemical processing industries where hygiene and reliability are critical.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment.
• Install the U-cup packing with the lips facing the correct direction (typically down) as specified in the manual.
• Lubricate the displacement rod and packing area before installation to facilitate assembly and reduce wear.
• Use steady force to seat the U-cup assembly properly in the cylinder.
• Follow all manufacturer guidelines for tightening and securing components to prevent leaks and ensure safety.
• Regularly inspect the U-cup packing for wear or damage.
• Replace the packing as part of routine maintenance or at the first sign of leakage.
• Use only genuine GRACO replacement parts for best results.
