Key Specifications

Part Number 165672
Type V-Packing (vee-ring seal)
Material PTFE (polytetrafluoroethylene)
Typical Location Throat / piston packing stacks in PTFE-packed pump designs
Primary Function Dynamic sealing under pressure with low friction and broad chemical compatibility

Features & Benefits

  • OEM geometry for proper stack compression and sealing integrity
  • Low friction for smooth rod movement and reduced wear
  • Resistant to many solvents and aggressive fluids used in industrial pumping
  • Helps maintain pressure, reduce leaks, and extend pump service intervals

Fit Notes & Verification

  • Compatibility depends on the pump’s packing configuration (PTFE-packed variants).
  • Always verify by model/serial against the exploded parts diagram for your machine.
  • If your pump uses leather/UHMWPE/Hycar stacks, confirm the correct kit before ordering.

Installation Guidance (General)

  • Fully depressurize and lock out the system before service.
  • Clean bore and inspect rod surface for scratches or corrosion.
  • Observe correct vee-ring orientation per the service manual for your pump.
  • Compress gland to the specification provided for the model; over-compression can shorten seal life.

Frequently Asked Questions

Check your model’s parts list or exploded diagram and confirm the packing stack callout. If the diagram specifies PTFE vee-packings with this part number, 165672 is correct for your unit.

Use the stack composition specified by the manufacturer. Mixing materials or changing the order can affect sealing, friction, and service life.

Follow the service manual for your pump. Some procedures use compatible light assembly lubricant to ease installation and protect the packing during the first cycles.

Loss of pressure, visible leakage at the throat, excess weepage, chatter, or accelerated rod wear. Inspect and replace the packing stack if these symptoms appear.
