Overview & Key Details

The Graco 165102 PTFE Vee Packing is a chevron-style sealing ring used in Graco displacement pumps to seal around a moving rod/shaft. PTFE provides low friction, chemical resistance, and long service life in demanding spray applications.

Compatible Machines

  • Check your sprayer’s exploded parts diagram for the displacement pump section.
  • If the parts list shows 165102 for the throat/rod vee-packing, this part fits your machine.
  • If a different packing number is listed, use that exact number instead.

Key Features

  • PTFE chevron ring for low friction and reduced wear.
  • Resists a wide range of coatings and solvents.
  • Maintains seal under high pressure and continuous cycling.
  • Designed for precise sealing in Graco pump packing stacks.

Technical Details

Part Number 165102
Material PTFE (Teflon®)
Seal Type Chevron / Vee packing (single ring for a stacked assembly)
Typical Location Displacement pump packing stack (throat/rod area – refer to your manual)
Application Airless paint sprayers using Graco pump assemblies that specify 165102

What’s Included

  • 1 × PTFE vee-packing ring (part 165102). Note: Packings install in a stack; order quantities accordingly.

Pro Tips

  • Keep the wet-cup properly filled with compatible pump lubricant to maximize packing life.
  • Adjust the packing nut per manual guidance—tighten only enough to stop leakage.
  • Inspect the rod for scoring; damaged rods shorten packing lifespan.

Frequently Asked Questions

Open your sprayer’s manual and go to the displacement pump exploded view. If the parts list calls out 165102 for the packing stack, it’s the correct part. If another number is listed, use that exact number instead.

It is typically a single PTFE vee-ring used within a stacking assembly. Many pumps require multiple rings (PTFE and/or leather/UHMW) in a specific sequence—follow your model’s assembly diagram and order the needed quantity.

Persistent paint leakage from the wet-cup area, difficulty holding pressure, uneven spray pattern, or frequent pressure drops typically point to packing wear. Inspect the rod and replace the packing stack as needed.

Yes. Maintain proper wet-cup fluid level with a compatible pump lubricant to reduce friction and extend packing life, even with PTFE rings.
