Product Details

The Graco 167677 Nut Packing is a precision component designed for securing and adjusting the packing set within the pump housing. It helps maintain proper sealing and reduces fluid leakage by compressing the pump packings correctly.

This part is commonly found in Graco displacement-style pumps. It ensures optimal performance and reduces premature packing wear when properly adjusted. Over-tightening should be avoided to maintain packing life.

Key Features

• OEM manufactured for reliable sealing performance
• Supports proper compression of pump packing assemblies
• Enhances fluid containment and reduces leakage
• Suitable for heavy-duty paint spraying systems

When to Replace

• Visible thread wear or damaged nut surface
• Persistent leakage around pump packing area
• Inability to maintain correct packing tightness

Maintenance Tip

Tighten the packing nut only enough to stop leakage; excessive tightening increases packing wear. Always use genuine OEM parts for best results.
