Graco 166624 PTFE O-Ring Packing – Details & Compatibility

Compatible Machines

This PTFE O-Ring Packing is used in specific Graco pump assemblies that require a chemically resistant seal.

  • Graco Displacement Pump – 247599 (Series A)

Product Overview

The Graco 166624 PTFE O-Ring Packing is a high-durability sealing component designed for applications where chemical resistance, heat stability, and long service life are critical. Made from PTFE, it provides excellent compatibility with solvents, coatings, and demanding spraying materials.

This O-ring is commonly used inside Graco pump sections to maintain a tight, leak-free seal between moving and static components. PTFE reduces friction and resists swelling, making it ideal for heavy-duty or high-solvent environments.

Key Features

  • High-grade PTFE construction for maximum chemical resistance
  • Maintains sealing integrity under high pressure
  • Reduced friction for smoother pump operation
  • Designed for harsh coatings and solvent-based materials

Technical Notes

PTFE O-rings have lower elasticity than rubber, so careful installation is necessary. Avoid twisting the ring during assembly and ensure all surfaces are clean and lubricated according to Graco service instructions.
